Overall Summary

This Research Laboratory Sample Submission Form is a well-structured, comprehensive instrument that guides users through registering specimens for laboratory analysis or experimental investigation. The form is organised into thirteen logically sequenced sections — from submission overview and contact details through project authorisation, sample inventory, sample identity, provenance, requested analysis, storage and handling, safety, timing and cost, data handling, supporting files, declarations, and optional feedback. This progression mirrors the natural workflow of preparing a laboratory submission, moving from administrative basics to technical detail and finally to confirmation and feedback. The form collects a rich breadth of information — researcher identity, institutional affiliation, project references, sample characteristics, collection provenance, analytical requirements, handling conditions, and hazard awareness — in a single organised workflow, which should support efficient triage and planning by laboratory staff.

A notable strength is the extensive use of conditional follow-up logic. Many questions deploy follow-up fields that appear only when relevant, such as asking for a previous submission reference only when a follow-up is indicated, or requesting containment details only when a specialised arrangement is expected. This design keeps the form relatively efficient for straightforward submissions while still capturing depth when needed. The form also includes a sample inventory table with pre-populated example rows, which helps users understand the expected format. Clear instructional paragraphs precede each section, setting expectations and reducing ambiguity. The inclusion of an optional feedback section at the end demonstrates attention to continuous improvement without burdening the core submission process.

From a data collection perspective, the form is designed to produce a structured, traceable record of each sample submission. Fields for project identifiers, sample codes, collection dates, quantities, and storage conditions support downstream record-keeping, sample tracking, and result attribution. The hazard and safety section gathers information that can assist laboratory personnel in planning appropriate handling. It is worth noting that the form itself states it does not replace institutional, local, or project-specific procedures — a prudent caveat that sets accurate expectations. Regarding privacy, the form collects personal contact details, institutional information, and potentially sensitive research context. Operators should ensure that data protection practices and retention policies are communicated to submitters in line with their own institutional arrangements.

From a user experience perspective, the form is lengthy but well-signposted. The section headings, introductory paragraphs, placeholder examples, and conditional logic all contribute to clarity. The primary friction points are the overall length and the number of required fields — 33 fields are marked as mandatory, which could challenge completion rates for users with simple submissions. However, the progressive nature of the form (moving from overview to detail) and the use of optional fields for secondary information help manage this. The signature and declaration section at the end provides a natural closing ritual that reinforces accuracy expectations.

Section-by-Section Analysis

Submission Overview and Instructions

The section begins with two instructional paragraphs that set expectations clearly. The first explains the purpose of the form and the importance of accurate, complete information for handling, instrument allocation, and results delivery. The second paragraph wisely notes that the form is a general-purpose template and does not replace institutional or project-specific procedures — a realistic and helpful disclaimer.

Submission date anchors the submission in time, providing a reference point for processing, scheduling, and record-keeping. It helps laboratory staff understand when a request was made relative to sample receipt and collection dates.

Who is completing this form? captures the submitter's role, which helps the laboratory understand the requester's authority, familiarity with the project, and the appropriate communication style. The follow-up for 'Other' allows flexibility for roles not listed.

Is this a new submission or a follow-up to an existing submission? is an effective routing question. The conditional follow-ups — asking for a previous submission reference, an explanation of sample damage, or the sampling round number — allow the laboratory to link submissions appropriately and avoid confusion. This question supports continuity across time-series studies and replacement scenarios.

Researcher and Contact Details

This section collects the essential contact information needed to communicate about the submission and return results. The paragraph clarifies the distinction between primary contact and alternative result recipients, which is practical.

Full name of primary contact establishes who the laboratory should communicate with, forming the basis for all correspondence. Email address serves as the primary digital communication channel and is essential for sending confirmations, questions, and results. Institution or organisation name provides context for the submission source and may influence internal versus external processing workflows.

Job title or study role and Phone number are helpful supplementary details that can assist in reaching the right person quickly or understanding their expertise level.

Department, faculty, or research group and Postal or delivery address for return of materials add useful organisational context and logistical information for material returns.

What is your relationship to the laboratory? helps the laboratory understand access levels, billing arrangements, and communication protocols. The follow-up requesting supervisor details for student submissions is a thoughtful design choice that ensures appropriate oversight.

Should results be sent to someone other than the primary contact? with its conditional follow-ups demonstrates attention to real-world reporting needs, where multiple stakeholders may require results in different formats.

Project and Authorisation Details

Project information links samples, costs, and results to the correct study — a critical organisational function. The introductory paragraph communicates this clearly.

Project title and Project ID or grant reference are the core linking fields, enabling the laboratory to associate submissions with the correct study records. Name of principal investigator or project owner identifies the responsible individual for authorisation and escalation purposes.

Funding source or cost centre and Purchase order, billing code, or internal account reference support cost allocation and financial processing where applicable.

Has this project received review or approval from an ethics, biosafety, or equivalent oversight body? is handled with appropriate sensitivity — allowing submitters to note that review was not required or is pending, without presuming any specific regulatory context. The follow-up fields accommodate both disclosure and explanation scenarios.

How will the laboratory costs for this submission be covered? helps the laboratory plan financial processing. Brief summary of the study objective relevant to this submission provides valuable scientific context that can help laboratory staff select appropriate methods.

Sample Inventory Overview

This section facilitates bulk sample tracking. The introductory paragraph and example rows in the table help users understand the expected format.

Total number of sample containers being submitted provides an immediate count for logistics planning and receipt verification.

The Sample Inventory table collects structured per-sample data — Sample ID, name, matrix/type, quantity, unit, collection date, special handling flag, and notes. This tabular format is efficient for multi-sample submissions and supports sample tracking throughout the laboratory workflow. The pre-populated example rows serve as helpful templates.

Does any single sample consist of multiple sub-aliquots that must remain linked together? addresses a real analytical scenario where aliquot linkage matters. The conditional follow-up allows the submitter to describe linkage requirements clearly.

How are the samples physically packaged for delivery? helps the laboratory prepare for receipt and handling. The conditional follow-ups for separate packages and custom arrangements add useful logistical detail.

Sample Identity, Type and Description

This section focuses on the main sample material in detail. Clear descriptions help laboratory staff select suitable preparation methods and analysis conditions.

Primary sample ID or code and Sample name or common label provide the two key identification fields — a formal code and a human-readable label — which supports both record systems and laboratory bench work.

What is the broad category of the sample material? is a key classification question with extensive conditional follow-ups for biological material form, organism/strain designation, chemical name, and extract preparation method. This branching logic efficiently captures category-specific details without burdening users with irrelevant fields.

Detailed description of the sample, including origin, appearance, and any known composition captures qualitative characteristics that support method selection and hazard assessment. The placeholder example is helpful and encourages thorough responses.

What is the physical state of the sample as submitted? with its conditional follow-up for frozen samples (including storage temperature and thawing events) shows attention to sample integrity concerns.

Quantity of the primary sample and Unit of the quantity above together define the sample size unambiguously, with the unit selection including mass, volume, count, and container options. Is the sample quantity limited or non-renewable? alerts the laboratory to preserve material where needed.

Is the sample a reference, control, or comparator material? helps identify quality-relevant materials. The follow-up classification and certificate number capture additional context for reference materials.

Which characteristics of the sample are already known or previously measured? allows the laboratory to leverage existing data and avoid redundant measurements. The multiple-choice format with conditional follow-ups for concentration values and additional characteristics is well designed.

Collection and Provenance Information

Provenance details support result interpretation, reproducibility, and cross-study comparison.

Date of collection and Time of collection establish the temporal context. Collection location or site description records the spatial or procedural context. The optional geographic coordinates field respects user preferences while supporting location-sensitive studies.

Collection method or protocol used captures the sampling procedure, which is important for reproducibility and result interpretation.

Who collected the samples? with follow-ups for named individuals, organisations, services, and archives supports chain-of-custody awareness.

Were any treatments, additives, preservatives, or fixatives applied at or after collection? is critical for understanding sample chemistry and selecting compatible analysis methods. Have the samples been analysed previously? helps avoid duplication and provides context. Is any portion of the sample being submitted now being retained elsewhere? supports sample management planning.

Any additional provenance details, chain-of-custody notes, or sampling conditions provides a free-text space for capturing transport conditions and other situational details.

Requested Analysis and Testing

This section is the analytical core of the form. The introductory paragraph encourages users to describe their research question if unsure, which supports a collaborative approach to method selection.

Which types of analysis are you requesting? uses a comprehensive multiple-choice list spanning separation, spectroscopic, microbiological, molecular, immunoassay, imaging, physical, elemental, cell-based, and consultation options. The conditional follow-ups for each category capture technique-specific details, which is excellent for method routing.

Detailed description of the requested analysis, including target measurand or analyte is essential for scoping the work accurately. What level of analytical rigour do you need? distinguishes between screening, semi-quantitative, quantitative, and validated approaches — a practical distinction that affects time, cost, and methodology.

What is the expected concentration range of the target in the samples? helps the laboratory select appropriate calibration ranges and detection methods. Do you require method development or optimisation? distinguishes routine analysis from development work.

Is a specific method, protocol, or standard procedure to be followed? accommodates scenarios where a named internal method, published method, or collaborator protocol must be used. The file upload option for collaborator-supplied protocols is a practical addition.

Which quality controls should be included in the analytical run? empowers the submitter to specify their quality expectations. Will you supply your own calibration standards, controls, or reference materials? alerts the laboratory to incoming reference materials.

How are results expected to be reported?, Preferred units for reported results, and Number of replicate measurements requested per sample together define the deliverable clearly, reducing ambiguity in output specifications.

Storage, Handling and Transport Requirements

This section addresses sample integrity during storage and transit — a critical operational concern.

What is the current storage condition of the samples? and What storage condition should the laboratory maintain after receipt? together capture the full storage chain. Both use detailed option lists with temperature-specific follow-ups, which supports precise handling planning.

Which special handling conditions apply to these samples? provides a comprehensive multiple-choice list covering temperature, light, orientation, agitation, atmosphere, humidity, sterility, and containment concerns. This is a well-designed checklist for handling planning.

Is there a limited window of time within which analysis should begin after collection or receipt? addresses time-sensitive samples and helps the laboratory prioritise appropriately.

How will the samples be delivered to the laboratory? with follow-ups for courier references and tracking numbers supports logistics coordination. Is a temperature monitor or data logger travelling with the shipment? captures transport conditions where available.

Additional handling, orientation, or transport instructions provides free-text space for unusual requirements. Should any unused sample material be returned to you after analysis? with its conditional follow-ups for return or disposal preferences ensures sample disposition is clearly defined.

Hazards, Safety and Regulatory Considerations

This section gathers information to assist laboratory personnel in planning safe handling. The introductory paragraph appropriately notes that the form does not replace local safety assessment, training, or approval processes.

Are you aware of any hazard associated with the sample material? is the primary hazard awareness question. The conditional follow-up captures specific hazard categories, while the 'no' branch notes that routine precautionary handling will still be applied — a balanced and responsible framing.

Does the sample contain or come from a biological source with potential to multiply? and Does the sample contain genetically modified, engineered, or otherwise specially derived material? help identify materials that may require specific containment or documentation.

Has any hazardous substance been added to the sample during collection or preparation? ensures chemical additives are accounted for in handling plans. What level of containment does the submitter expect to be appropriate? captures the submitter's assessment while leaving room for laboratory guidance.

Which accompanying safety documentation can you provide? with its multiple-choice options and file upload field supports comprehensive safety file compilation. Is there any restriction on who may handle these samples? and Are there any decontamination, cleaning, or disposal instructions? capture additional operational constraints.

Timing, Priority and Cost Considerations

The introductory paragraph manages expectations by noting that scheduling will be confirmed separately and completion does not guarantee a particular date.

Preferred date for analysis to begin and Date by which results are needed help with scheduling. What level of urgency applies to this request? with its four levels (routine, priority, time-critical, flexible) is a clear prioritisation tool. The conditional follow-up for time-critical requests asks for explanation, which supports realistic scheduling.

Is the timing linked to an external deadline? helps the laboratory understand the broader context. How would you like progress updates to be handled? lets submitters set communication preferences.

Is a cost estimate or quotation required before work begins? and Approved budget amount support financial planning. Who should receive the invoice or internal recharge notice? with follow-up contact details ensures billing is directed correctly.

Results, Data Handling and Publication Preferences

This section addresses how results and data should be delivered, stored, and referenced.

In which formats would you like to receive results? offers a comprehensive list from PDF reports to machine-readable exports. How should results be delivered? covers email, secure transfer, portal, post, and in-person options with appropriate follow-ups.

How long should the laboratory retain the raw data and records? provides options from short-term to extended archival, with a 'not sure' option. Do you wish to be consulted before any repeat analysis? respects the submitter's preference for involvement in method decisions.

May the laboratory retain anonymised or de-identified method performance information? addresses internal quality monitoring with clear yes/no follow-ups that set expectations transparently.

How should the laboratory be acknowledged in any resulting publication or report? covers acknowledgement preferences including named staff and contribution wording. Would you like to be notified if the laboratory identifies an unexpected or unusual result? with its notification method follow-up demonstrates commitment to communication.

Supporting Files and Attachments

Three file upload fields — sample log, chain-of-custody record, or collection worksheet; method description, protocol, or reference material; and previous results, figures, or supporting data — provide structured opportunities to attach relevant documentation. The comments about attachments field accommodates large files and additional information, which is a practical touch.

Declarations and Confirmation

This section provides a clear closing sequence of confirmation statements and signature fields.

The three mandatory checkboxes — accuracy and completeness confirmation, authorisation to submit, and hazard disclosure confirmation — establish accountability expectations. The two optional checkboxes regarding scheduling understanding and contact agreement add helpful context without creating barriers.

How did you hear about this sample submission process? supports process awareness, while Any final comments captures additional context. Type your full name as your signature, Signature, and Date of signature provide a complete attestation sequence.

Submission Experience Feedback

The optional feedback section — with star rating, emotion rating, matrix rating across five statements, and an open-ended improvement suggestion — is well designed for gathering actionable user experience data. The introductory paragraph reassures users that feedback is not used to assess scientific merit, which encourages honest responses.

Overall Strengths and Areas for Consideration

The form's primary strengths include its comprehensive coverage of operational, technical, and logistical dimensions of sample submission; its effective use of conditional follow-up logic to reduce irrelevant fields; clear section-level instructional text; pre-populated table examples; and a thoughtful balance between structured choices and free-text flexibility. The thirteen-section structure mirrors real laboratory workflows and should support efficient processing.

Areas for potential consideration include the overall length of the form, which may affect completion rates for simple submissions — though the conditional logic mitigates this. The number of mandatory fields (33) is notable and may warrant review to ensure each is genuinely essential for processing. Some sections, particularly 'Requested Analysis and Testing' and 'Storage, Handling and Transport Requirements', are quite detailed and could potentially benefit from progressive disclosure or summary views. Additionally, the form could benefit from a progress indicator or section navigator given its length. Despite these considerations, the form represents a thorough and well-designed submission instrument that should serve diverse laboratory submission scenarios effectively.

Individual Mandatory Question Analysis

Submission date
Requiring this field ensures that every submission is timestamped at the point of entry, providing a reference point for processing timelines, scheduling, and record-keeping. When sample receipt dates or analysis start dates differ from the submission date, having this anchor supports accurate tracking and audit trails. This field is generally considered operationally important for any submission-based workflow.

Who is completing this form?
Requiring the submitter's role supports appropriate communication and authority verification. It helps laboratory staff understand whether they are interacting with a principal investigator, student, external collaborator, or support staff member, which may influence how follow-up questions are directed. Capturing this early in the form reduces ambiguity in later correspondence.

Is this a new submission or a follow-up to an existing submission?
This routing question is essential for linking submissions to prior records, avoiding duplicate sample entries, and correctly handling replacement or continuation scenarios. Requiring it ensures that laboratory staff can immediately determine whether to start a new record or update an existing one. The conditional follow-ups further capture the specific reference or context needed.

Full name of primary contact
Requiring the primary contact name ensures that every submission is associated with a clear point of accountability and communication. This supports correspondence, results delivery, and record attribution. In multi-stakeholder projects, having a single designated contact reduces the risk of misdirected communication.

Email address
Marking the email address as mandatory supports reliable digital communication for submission confirmations, follow-up queries, and results delivery. It serves as the primary touchpoint for ongoing correspondence. Operators should ensure that any data protection notices are communicated to submitters regarding how contact details will be used and stored.

Institution or organisation name
Requiring the institution or organisation name helps classify the submission as internal or external and supports administrative processing, billing arrangements, and record organisation. It provides essential context for laboratory staff to understand the submitter's institutional relationship and any applicable access or processing arrangements.

What is your relationship to the laboratory?
This field helps the laboratory determine access levels, communication protocols, and potentially billing categories. Requiring it ensures that each submission is correctly classified from the outset, which may influence how the laboratory processes the request. The conditional follow-up for supervisor details further supports appropriate oversight for student submissions.

Project title
Requiring the project title ensures that each submission can be clearly associated with its parent study. This supports record organisation, cost allocation, and result attribution. A descriptive project title helps laboratory staff quickly understand the scientific context of the work.

Project ID or grant reference
This field is critical for linking the submission to the correct project record, budget line, and reporting framework. Requiring it ensures that samples, costs, and results can be accurately tracked and attributed. For multi-project environments, this reference is often the primary key for record association.

Name of principal investigator or project owner
Identifying the responsible investigator supports authorisation verification, escalation pathways, and project-level accountability. Requiring this field ensures that the laboratory has a clear reference for the individual ultimately responsible for the research project associated with the submission.

How will the laboratory costs for this submission be covered?
Requiring cost coverage information supports financial planning and processing, helping the laboratory determine billing routes and ensure appropriate cost attribution. While the specific cost arrangements may vary by institution and project, having this information upfront can reduce administrative delays later in the workflow.

Total number of sample containers being submitted
Requiring a container count supports logistical planning — including storage allocation, receipt verification, and inventory reconciliation. It provides an immediate reference point that can be checked against the detailed sample inventory and upon physical receipt.

Primary sample ID or code
Requiring a sample identifier ensures that each primary sample is uniquely identified in laboratory records. This supports sample tracking, result attribution, and record-keeping throughout the analysis workflow. Consistent sample identification is generally fundamental to organised laboratory operations.

Sample name or common label
Requiring a human-readable sample name alongside the formal code supports clear communication at the bench and in reporting. Laboratory staff frequently refer to samples by descriptive names, so capturing this alongside the identifier reduces confusion and improves the usability of records.

What is the broad category of the sample material?
Requiring the sample category ensures that laboratory staff can immediately assess the appropriate handling, preparation, and analysis approach. This classification drives method selection and resource allocation. The extensive conditional follow-ups capture category-specific details that further support planning.

Detailed description of the sample, including origin, appearance, and any known composition
Requiring a detailed description ensures that laboratory staff have sufficient qualitative information to plan sample preparation and analysis appropriately. Descriptions of origin, appearance, and composition help identify potential interferences, guide method selection, and support result interpretation.

Quantity of the primary sample
Requiring the sample quantity supports method selection (ensuring sufficient material for the requested analysis), storage planning, and resource allocation. It also helps the laboratory determine whether the submitted amount is adequate for the requested tests and any quality controls.

Unit of the quantity above
Requiring the unit of measurement ensures that the sample quantity is unambiguous. Without a unit, the quantity is not actionable. The comprehensive option list covers mass, volume, count, and container units, accommodating diverse sample types.

Date of collection
Requiring the collection date establishes sample age and provenance, which is important for interpreting results and assessing sample integrity. Samples collected at different times may require different handling or analysis considerations, making this temporal reference valuable for laboratory planning.

Collection location or site description
Requiring the collection location supports provenance recording and result interpretation. Understanding where samples were obtained helps laboratory staff contextualise results and may influence analysis approach. For field studies, this information is often essential for reproducibility.

Which types of analysis are you requesting?
Requiring the analysis type is fundamental to scoping the work, allocating appropriate instruments and personnel, and scheduling laboratory capacity. The comprehensive option list with conditional technique-specific follow-ups ensures that the laboratory can route the request to the correct analytical area efficiently.

Detailed description of the requested analysis, including target measurand or analyte
Requiring a detailed analysis description ensures that the laboratory fully understands what is being asked. This reduces the risk of misinterpretation, scope creep, or rework. Clear description of the target measurand or analyte supports method selection and calibration planning.

What level of analytical rigour do you need?
Requiring this field helps the laboratory allocate appropriate resources — screening analyses differ significantly from validated quantitative methods in terms of time, cost, and methodology. Capturing this expectation upfront supports realistic scoping and prevents mismatches between the work delivered and the work expected.

What is the current storage condition of the samples?
Requiring the current storage condition ensures that laboratory staff understand the state in which samples are being received and can plan appropriate interim handling. It also supports assessment of sample integrity and potential degradation that may affect analysis results.

What storage condition should the laboratory maintain after receipt?
Requiring the post-receipt storage requirement helps the laboratory allocate suitable storage resources (e.g. freezer space, refrigeration, incubation) and maintain sample integrity throughout the analysis period. This is a practical operational necessity for organised sample management.

Are you aware of any hazard associated with the sample material?
Requiring this question ensures that every submitter has the opportunity to disclose known hazards. Even where the answer is negative, the required response establishes that the question was considered and addressed. This supports safe handling planning and is a responsible operational practice. The form appropriately frames this as an awareness question rather than a regulatory requirement.

What level of urgency applies to this request?
Requiring the urgency level helps laboratory staff prioritise submissions and schedule instrument time appropriately. It establishes expectations for turnaround and supports capacity management. The form wisely includes a 'flexible' option to accommodate submissions without time pressure.

I confirm that the information in this form is accurate and complete to the best of my knowledge.
Requiring this confirmation checkbox establishes that the submitter has reviewed their responses and vouches for their accuracy. It promotes careful completion and provides a clear attestation point for record-keeping. This is a common and practical practice in submission-based workflows.

I confirm that I am authorised to submit these samples and to request the described analysis on behalf of the research project.
Requiring this authorisation confirmation supports accountability and ensures that submissions are made with appropriate authority. It helps prevent unauthorised submissions and establishes the submitter's role in the process. The form appropriately frames this as a self-declaration rather than a verified authorisation process.

I confirm that any hazards or special handling requirements known to me have been described in this form.
Requiring this confirmation ensures that the submitter has actively considered and disclosed safety-relevant information. It reinforces the importance of the hazard section and provides a clear attestation that safety disclosures are complete to the best of the submitter's knowledge.

Type your full name as your signature
Requiring the typed full name serves as the first component of the attestation sequence, linking the declaration to a specific individual. It supports record completeness and traceability.

Signature
Requiring a signature (whether drawn or typed, depending on the form implementation) provides a formal attestation that the submitter endorses the declarations made. This is a standard practice for establishing accountability in submission records.

Date of signature
Requiring the signature date establishes when the attestation was made, supporting record completeness and temporal accuracy. It provides a clear reference point for when the declarations were confirmed, distinct from the submission date if these occur at different times.

Overall Mandatory Field Strategy

This form contains 33 mandatory fields spread across 13 sections. While each required field serves a clear operational purpose, the total number is notable and could present a completion barrier for users with straightforward submissions. The following strategic observations and recommendations may be useful:

• Balancing data depth against completion rates: The form currently requires core identification, project reference, sample description, analysis specification, storage conditions, hazard awareness, and declaration fields. This is a reasonable set for a comprehensive submission process. However, form administrators may wish to review whether all 33 fields are essential for the initial processing stage, or whether some (such as cost coverage or urgency level) could be collected at a later processing step. Reducing the mandatory count even by a few fields can measurably improve completion rates.
  
  
• Effective use of conditional logic: The form already uses conditional follow-ups extensively, which is a strength. Consider extending this principle to some mandatory fields — for example, cost coverage details might only be required when the submission is external or billable, and urgency level might be relaxed for submissions not tied to deadlines. Conditional requirement logic (requiring a field only when a prior answer makes it relevant) can reduce perceived form burden without sacrificing data completeness.
  
  
• Mandatory field placement and grouping: The mandatory fields are distributed across the form from beginning to end, including three checkboxes and two signature fields at the conclusion. This distribution is logical and mirrors the form's workflow structure. However, the three mandatory declaration checkboxes plus mandatory typed name, signature, and date at the end represent six required fields in the final section alone. Consider whether all six are necessary or whether the checkbox declarations alone might suffice for certain submission contexts.
  
  
• General best practices for mandatory field selection: Focus required fields on information that is genuinely needed for the laboratory to process the submission — identity, sample identification, analysis specification, and handling requirements. Fields that support optional enrichment (such as detailed provenance, cost information, or publication preferences) are well-placed as optional. Periodically review mandatory field justification against actual processing workflows and user feedback to ensure the requirements remain proportionate.
  
  
• User communication about required fields: The form's introductory text clearly states that required fields must be completed, which is helpful. Consider adding visual indicators (such as asterisks or colour coding) to required fields throughout the form, and a brief summary or checklist of required information before the submission section, to help users prepare before starting.
