Custom Software Requirements Checklist

Use this custom software requirements checklist to define users, workflows, records, permissions, integrations, reporting, rollout, and support.

Key takeaways

  • Requirements should describe business behavior and decisions, not only screens.
  • Exceptions, permissions, reports, integrations, and ownership need the same attention as the happy path.
  • A clear first-release boundary prevents the requirements document from becoming an unlimited wish list.

A useful requirements set connects each requested capability to a user, decision, record, and business outcome.

Start with people, responsibilities, and outcomes.

List each user type and what that person must accomplish. Owners, managers, staff, customers, and vendors often need different views and permissions.

For each workflow, define the operational outcome: faster intake, fewer missed handoffs, cleaner reporting, less duplicate entry, or better customer visibility.

  • User roles and responsibilities
  • Business owner and project sponsor
  • Decisions the system must support
  • First-release success criteria

Document the workflow and its exceptions.

Describe the trigger, required information, statuses, handoffs, reminders, approvals, and completion condition. Then document what happens when information is missing, duplicated, rejected, delayed, or changed.

Real operations contain exceptions. Ignoring them during requirements work simply pushes those decisions into development or production.

Define data, permissions, integrations, and reporting.

List the records the business needs, where current data lives, who may view or edit it, and which reports use it. Identify systems that may connect and who controls those accounts.

Do not assume a provider supports the desired integration. Record API access, exports, webhooks, account plan, approval requirements, and fallback options as discovery items.

Set release boundaries and ownership.

Separate required first-release capability from later opportunities. Define migration, training, documentation, hosting, backups, vendor accounts, support, and who approves production changes.

These operational requirements prevent custom software from becoming unsupported code after launch.

FAQ

Do requirements need to specify every screen?

No. Start with users, workflows, records, rules, exceptions, and outcomes. Screen details can be refined after the behavior is understood.

Who should approve software requirements?

The operational owner, project sponsor, and representative users should review the requirements for the workflows they understand.

Should future features be included?

Keep them in a later-opportunities list so they inform architecture without expanding the first release without control.

Have a workflow that needs to become clear requirements?

Bring the current process, users, tools, exceptions, and reporting needs into discovery before choosing features.
