How to Brief a Software Development Partner: A Practical Checklist

A useful software development brief explains the problem you want to solve, the people who will use the product and the constraints that could shape the work.

You do not need to document every screen before speaking with a development partner. You do need to make your priorities and uncertainties visible.

This guide covers what to prepare for an initial conversation, whether you are starting a new product or asking an outsourced team to work on an existing one.

1. Explain the business problem

Start with the reason for the project.

What is difficult today? Who experiences that difficulty? What should improve once the software is in use?

“Build a mobile app” leaves many questions unanswered. A more useful description might be:

“Customers currently call our team to book services. We want them to see availability and make a booking themselves.”

That gives a development partner something concrete to investigate. They can ask how availability is managed, what customers need to know before booking and which exceptions require staff involvement.

If you have a success measure, include it. It could relate to task completion, staff workload or adoption. Explain how you expect to measure it, and distinguish an intended outcome from a result you have already demonstrated.

2. Identify the users and their tasks

Different users may need different parts of the product.

For example, a customer might make a booking, a staff member might manage availability and an administrator might control access.

For each group, describe:

• Who they are.
• What they need to accomplish.
• What information they need.
• Which devices or environments they use.
• What they should be allowed to access or change.

You do not need detailed personas to begin. A short description of each user group and its main tasks is often enough for an initial discussion.

3. Describe the essential user journeys

A feature list gives an overview. A user journey explains how the features fit together.

Choose the most important tasks and describe them from start to finish.

For a booking journey, you might explain how a customer:

• Finds the relevant service.
• Selects an available date and time.
• Provides the required details.
• Confirms the booking.
• Receives confirmation.
• Changes or cancels the booking, if permitted.

Include the important exceptions. What happens if the selected time is no longer available? Can a customer book without an account? Does a staff member need to approve the request?

You can leave questions unanswered. Label them as open questions rather than allowing them to become hidden assumptions.

4. Explain what already exists

An existing product changes the starting point.

List any assets and systems that may be relevant:

• Designs: Whether they are exploratory, approved or already implemented
• Code: Which parts exist, their current status and who maintains them
• APIs: Available documentation, owners and test environments
• Infrastructure: Where the product runs and who manages it
• Documentation: What it covers and whether it is current
• Release process: How software reaches users and who controls the necessary accounts

For an initial conversation, a high-level inventory may be sufficient. Detailed access can be arranged later.

Keep passwords, tokens, production data and other sensitive material out of the brief. If information is confidential, identify what is available and arrange appropriate sharing before providing it.

5. Define the first release

A long-term product vision and a first-release scope serve different purposes.

Explain both, but separate them.

A simple way to organise requirements is:

• Required for the first release: the product cannot fulfil its initial purpose without this.
• Useful later: valuable, but not necessary for the first release.
• Undecided: needs further discussion or investigation.

For each required item, explain why it is essential. This helps a development partner understand where scope can be adjusted and where it cannot.

Avoid describing everything as a launch requirement. If priorities compete, state which user journey or business objective takes precedence.

6. Make constraints and dependencies visible

Constraints can affect the proposed scope, team and delivery approach.

Include what you know about:

• Budget expectations.
• Target dates.
• Supported platforms.
• External integrations.
• Internal approval processes.
• Required security or compliance review.
• Availability of people who need to provide information or access.

If you have a deadline, explain its reason. A date linked to a contractual commitment creates different planning conditions from a preferred launch date.

If you have a budget range, share it where appropriate. It helps the discussion focus on a feasible scope.

Also name external dependencies. For example, a required integration may depend on documentation or test access supplied by another organisation.

7. Identify who makes decisions

An outsourced team needs to know who can answer questions and approve changes.

Identify:

• The person responsible for business priorities.
• The person who approves scope.
• The technical contact, if there is one.
• The people who review designs and demonstrations.
• Any additional approval steps.

Explain how conflicting feedback will be resolved. A clear decision process helps the team avoid implementing incompatible instructions.

8. List what you do not know yet

An incomplete brief can still be useful if its gaps are clear.

Create a short list of open questions. For example:

• We have not decided whether customers need accounts.
• We need to confirm which operations the external API supports.
• We do not yet know whether the existing code can be reused.
• We need help separating launch requirements from later features.

These questions may require a discussion, a technical review or a discovery phase before a reliable implementation plan can be prepared.

Ask the development partner which uncertainties matter most and what would be needed to resolve them.

An illustrative example

The following example is fictional. It is included to demonstrate how to structure a brief and does not describe a client project.

Initial request

“We need an iOS and Android app for booking services. It should include accounts, payments, notifications and an administration panel.”

This names several features, but leaves the purpose, priorities and dependencies unclear.

A more useful starting brief

• Business problem: Customers currently contact staff to ask about availability and make bookings
• Primary users: Customers making bookings and staff managing the schedule
• Essential journey: Find a service, select an available time, submit details and receive confirmation
• First-release scope: Booking and staff schedule management
• Undecided features: Whether accounts and online payments are necessary at launch
• Existing systems: A scheduling service is already in use; its integration options need investigation
• Platforms: Mobile access is required; the delivery approach is open for discussion
• Constraints: Budget expectations and launch timing will be discussed during scoping
• Decision-maker: One nominated business owner will approve priorities
• Open questions: Cancellation rules, integration capabilities and notification requirements

The second version gives both sides a clearer basis for discussion. It does not settle every decision, but makes the unresolved ones explicit.

What to ask a development partner next

Once you have shared your brief, ask:

• Which parts of the scope are clear enough to assess?
• Which assumptions are you making?
• What information is still missing?
• Which dependencies could affect delivery?
• What would you recommend investigating first?
• What will be included and excluded from the proposed work?

At an early stage, an estimate may depend on assumptions that still need validation. Ask for those assumptions to be documented so you can understand the conditions behind the proposal.

Project brief checklist

Before your first conversation, check that you can share:

• A short description of the business problem.
• The main user groups and their tasks.
• The essential user journeys.
• An inventory of existing assets and systems.
• First-release priorities.
• Known constraints and dependencies.
• The decision-making process.
• A list of open questions.

A short, clear brief is enough to begin a productive discussion. More detail can be developed as the important questions are resolved.
