Planning your project / Trionyx
How to scope a full stack application
Prepare a full stack project brief covering users, workflows, web and mobile interfaces, APIs, data, integrations and release responsibilities.
Start with one complete workflow
Describe the useful outcome a person should reach, rather than listing screens alone. For a field service product, that might mean assigning a job, completing a site report and preparing an invoice. For an operations platform, it might mean planning a shift and reviewing a report. List the steps, the people responsible and the points where information changes hands.
Define users and permissions
Write down the user roles and the actions each role can perform. Distinguish a customer, field worker, manager and system administrator where relevant. Clarify whether records belong to one organization or several separate customer accounts. Permission boundaries affect interface design, backend rules, testing and support; they should be part of the initial scope.
Connect the interfaces to shared records
A Flutter app, a browser dashboard and a backend can be separate applications within one product. Identify which information must appear in each interface and who can update it. List the core records, such as users, sites, jobs, documents or transactions. Shared APIs need consistent rules so the mobile and web experiences do not become disconnected versions of the same process.
List integrations and uncertain dependencies
Record the external systems, APIs, storage services and identity providers the application needs. State whether documentation, development accounts and sample data are available. Existing integrations may have limits or approval requirements. Include migration if the new application replaces spreadsheets or another platform. Use anonymized examples while discussing the scope; do not submit credentials through an enquiry form.
Agree how the first release will be accepted
Choose the workflow that makes the first version useful and separate later modules from that release. Define test cases for normal use, missing information, permission restrictions and service failures. Agree the target browsers and devices, expected data volume and document formats. Ask for reviews of a connected journey through interface, API and data, rather than accepting disconnected screens as a finished product.
Include release and ownership in the proposal
Clarify hosting, domain and third-party account ownership, environment configuration and source access. Separate implementation from ongoing subscriptions and maintenance. The handover should identify deployment guidance, support responsibilities and how changes are requested. Compare proposals against the same boundaries so you can understand what each estimate includes.
Turn the checklist into a brief.
Describe your goal, existing systems and first-release priorities. We will discuss feasibility and scope.
