How to Brief a Developer So They Build What You Actually Need

The strongest software projects do not start with a long list of features. They start with a clear understanding of the problem the software needs to solve.

A good development brief should explain what you need to achieve, who will use it and how the business works today. If you are preparing to write a software requirements brief, the aim is not to produce a technical specification, but to give a developer enough information to understand the project, ask the right questions and assess its scope.

Here is what to include.

1. Start with the business problem

Begin with why you need the software.

Perhaps your team transfers information between spreadsheets, customers cannot track orders, staff spend too much time on administration, or several systems do not communicate.

Explain what happens now, where the problems occur and what you want to improve.

For example:

“Our sales team records enquiries in spreadsheets before manually entering them into our CRM. This creates duplicated work and makes it difficult to see the latest customer information.”

That tells a developer considerably more than:

“We need a CRM.”

Understanding the existing process is an important part of scoping a software project because it can reveal requirements that are not obvious from a feature list.

2. Identify who will use it

List every type of person who will interact with the system.

This could include:

• customers

• sales staff

• administrators

• managers

• suppliers

• external partners

Then explain what each user needs to accomplish.

A customer might need to submit and track an enquiry, while an administrator may need to approve it, update records and produce reports.

Thinking through each user group early can uncover different permissions, workflows and functionality that might otherwise be missed.

3. Describe what the system needs to do

Explain the key functionality, focusing on what users need to achieve, rather than how the software should be built.

For example, instead of:

“Build a dashboard using [specific technology].”

say:

“Managers need to see open enquiries, their current status and the person responsible for each one.”

This gives the developer room to recommend an appropriate technical approach.

If you have spreadsheets, forms, screenshots, reports or process documents, include them. Showing the current process can be more useful than describing it in technical language.

4. Separate must-haves from nice-to-haves

Not every possible feature needs to be part of the first version.

Create two lists:

Must-haves

• essential for launch

• required for the main workflow

• necessary for users to complete their core tasks

Nice-to-haves

• useful but not essential

• potential future improvements

• features that can wait if they affect the initial scope

This helps everyone understand priorities when discussing the project, timescale and budget.

It also prevents every new idea from becoming an assumed requirement.

5. Explain what is outside the scope

A good software project brief template should identify what the project will not cover as well as what it will.

Consider whether the project includes:

• migrating existing data

• connecting other software

• customer-facing functionality

• reporting

• user training

• ongoing maintenance

• mobile access

You do not need to have every answer before approaching a developer. The important thing is to flag areas that need discussion rather than allowing assumptions to fill the gaps.

6. Tell the developer what already exists

Existing technology can affect how a new solution needs to work.

List the systems you currently use and explain what you want the new software to do with them, including any CRM, accounting platform, database, booking system, payment service or legacy application.

If information needs to move between systems, explain what you expect to happen.

For example:

“The new system needs to use existing customer information from our CRM.”

That is much more useful than simply saying:

“It needs an integration.”

7. Consider the requirements people cannot see

Not every requirement is a visible feature.

Depending on the project, you may need to consider:

• user access and permissions

• mobile use

• performance

• accessibility

• data protection and privacy

• security

• reporting

• backup and recovery

• future growth

If personal data is involved, explain what information the system will handle, who will use it and why. Relevant privacy and security requirements should be considered during planning rather than left until the end.

8. Explain your budget and timeline

You do not need an exact project cost before approaching a developer. If you have an approved budget or working range, share it to give useful context when discussing scope and priorities.

For timing, explain whether you have a fixed deadline or preferred launch date.

For example:

“We would ideally launch before September because our busiest sales period begins then.”

That gives more context than simply saying, “We need it by September.”

9. Understand why vague briefs affect estimates

Two businesses can ask for “a customer portal” but mean completely different things.

One might need a simple login and document area. Another might require payments, different user permissions, automated notifications, CRM integration and live reporting.

The headline feature is the same, but the work involved can be very different.

That is why what to tell a software developer should go beyond a list of features. Explain the users, workflows, integrations, priorities and constraints. The more important details a developer has to assume, the more uncertainty there can be around scope and estimates.

A clear brief cannot guarantee a fixed price, but it gives both sides a much stronger basis for discussing what the project actually involves.

10. Define what success looks like

Finally, decide how you will know the software has achieved its purpose.

Your success criteria might include:

• reducing manual data entry

• allowing customers to complete a process without calling the office

• giving managers clearer operational information

• automating a repetitive task

• reducing errors when transferring information

For important functions, you can also describe what successful completion looks like.

For example:

“A customer can submit an enquiry, receive confirmation and view its status without contacting the office.”

Clear acceptance criteria give everyone something practical to discuss and test.

A good brief starts the right conversation

Your brief does not need every technical answer. It simply needs to make the business problem, users, priorities and expectations clear enough for the developer to ask the right questions.
