From Requirement to Working System.
A software project becomes more dependable when the problem, workflow, logic, architecture and validation route are made visible.
Define the problem and intended outcome.
Identify users, responsibilities, constraints, existing systems and what successful software needs to enable.
Make the current and intended workflow visible.
Trace inputs, actions, hand-offs, decisions, exceptions and outputs before prescribing an interface.
Translate the requirement into system structure.
Define conceptual components, business logic, data relationships, access boundaries and dependencies.
Test flows before committing every detail.
Use agreed representations of screens and interactions to review hierarchy, sequence and user understanding.
Assemble the application against agreed scope.
Implement components, workflows and behaviours with progress and decisions made visible.
Connect approved external systems.
Implement technically suitable connections against available access, documentation, permissions and terms.
Check behaviour against requirements.
Complete agreed functional, workflow and acceptance activities, recording outcomes and required decisions.
Prepare the agreed delivery environment.
Deployment requirements, responsibilities, configuration and handover vary by project.
Assess future change deliberately.
Further iteration can be scoped when new requirements, evidence or operational priorities emerge.
What should the software actually do?
Tell us about the business problem, current workflow, users, systems and the outcome you are trying to achieve.
