Each guide answers a practical software planning or delivery question. It explains the relevant activities, technical considerations and information that helps businesses prepare.
Three areas of software development
Software discovery, architecture and delivery address different parts of development. Understanding these areas helps businesses prepare and organise technical work.
Software discovery and planning
Understand how to prepare a development job before choosing a technical approach.
- Identify the business problem and intended users
- Define the main functions and expected outcomes
- Review existing applications and processes
- Describe available information and system dependencies
Architecture and system design
Software architecture describes how application components, data and connected systems work together.
- Understand the purpose of system architecture
- Consider connections with existing applications
- Identify technical and operational requirements
Development, testing and delivery
Understand how software moves from agreed requirements into an application that people can use.
- Define the functions to be developed
- Organise work into manageable development stages
- Prepare representative testing scenarios
- Review functionality against agreed requirements
- Plan documentation and technical handover
Clear requirements and regular reviews help teams understand progress and identify where further adjustments may be useful.
Explore custom software developmentA practical approach to software planning
Understand the software need
Begin with the activity, problem or user requirement that the application should address.
You might want to improve an internal workflow, connect existing systems, modernise an application or create software for customers.
Explore the technical approach
Use the guidance to understand which development activities may be relevant.
Consider existing software, architecture, integrations, user interfaces and data requirements. The approach depends on what the system needs to do and how it will be used.

Continue to product discovery, software integration or legacy modernisation guidance. Choose the subject that answers your next question about the planned work.
What to know before starting development
Preparing the right information helps businesses explain their software requirements, understand technical dependencies and agree how development work will be organised.
Your software development question
Identify what you want to understand about creating or improving an application.
For example, a business may want to understand how to turn a manual process into a digital workflow or connect customer information across existing systems.
A product team may want to explore application architecture, development planning or how to organise testing.
Your application requirements
Think about what the software should do and who will use it.
Important details include the main functions, expected outputs, available information, existing applications and how people will interact with the system.
Your technical environment
Useful details can include:
- The intended users and software functions
- The existing applications and technologies
- The data needed for the planned system
- The technical connections and dependencies
- The people responsible for reviewing deliverables
Your delivery expectations
Describe the functionality that needs to be developed, the expected deliverables and how the work will be reviewed.
Consider testing, documentation and handover so the application can be understood and supported after development.
Apply software guidance to your project
Software development guidance becomes useful when you connect it to the application's purpose, existing technology, user requirements and expected deliverables.
Define requirements clearly
Begin with what the software needs to achieve.
Describe the intended users, key activities, expected outputs and existing business processes.
Discuss which functions matter to the initial scope and how the completed work can be evaluated.
Review existing technology
Identify the applications, databases and systems that may be involved.
Existing software can influence integration, architecture and testing decisions. Understanding these connections helps teams plan the technical work.
Prepare for testing and handover
Software testing helps teams review how an application behaves against agreed requirements.
Define the functions to test, the information needed and who will review the results. Include documentation and handover needs in the delivery plan.
A practical software development example
A business wants to develop a web application for managing customer requests and needs to understand requirements, system integration and delivery.
Identify the software requirement
A business wants to replace manual customer request tracking with a web application. The team describes its current process, expected functions and information needed for the work.
Review existing systems
The business identifies the customer database, existing forms and internal applications that the proposed software may need to use.
It reviews how information currently moves between systems and which employees need access to the new application.
Define the technical approach
The team considers a web application with request forms, status tracking and connections to the existing customer database.
They discuss the required functionality, data flow, access permissions and how users will interact with the application.
Organise development and testing
The business defines the expected deliverables, technical requirements, testing scenarios and information needed for development.
The work can be organised into agreed development stages. The employer chooses the talent, manages the collaboration and approves the completed work.
Review the completed application
The team tests the application using representative customer requests and checks whether the functions meet the agreed requirements.
Findings can inform further changes, user documentation and preparation for continued operation.
Software development preparation checklist
Before starting a software development job, use these questions to clarify the requirements, technical environment and expected deliverables:
- What business problem should the software address?
- Have I identified the main users and required functions?
- Do I understand the existing systems and dependencies?
- Have I considered architecture and integration needs?
- How will the application be tested and reviewed?
- Which software project guide answers my next question?

Understand software development decisions
Requirements, architecture, implementation and testing serve different purposes. Understanding these differences helps businesses make informed software decisions.
Understanding software requirements
Requirements describe what an application should do, who will use it and which outcomes are expected. They provide a starting point for technical planning and development discussions.
Understanding software architecture
Architecture describes how software components, data and integrations are organised. Different approaches may suit different application requirements and existing systems.
Practical examples
Examples illustrate how businesses may define requirements, plan applications, organise development and review deliverables. They are illustrative scenarios rather than individual customer stories.
Accurate technical information
Guidance should distinguish proposed functionality, agreed deliverables, technical assumptions and tested results without suggesting that software will perform beyond its defined requirements.
Find answers to software project questions
Begin with a clear question
Choose the specific part of software development that you want to understand.
For example:
- How do I prepare software requirements?
