How to Prepare a Software Project Brief
A clear brief saves weeks of back-and-forth and leads to more accurate estimates. Here is what to include — and what you can safely leave out.
A project brief is a short document that explains what you want to build and why. You do not need technical knowledge to write a good one. What matters is that a development team can understand your goals, your users and your constraints well enough to ask the right questions and give you a realistic estimate.
1. Start with the problem, not the solution
Describe the situation today and what is not working. "Customers call us to check order status, which takes up most of our support time" is more useful than "we need an app". A clear problem lets the team suggest the simplest solution that solves it — which is sometimes smaller than you expected.
2. Describe who will use it
List the types of people who will use the product: customers, staff, administrators, partners. For each, note what they need to do and in what context — on a phone at a construction site, on a desktop in an office, occasionally or every day.
3. List the essential features
Write down the features the first version cannot launch without. Then, separately, list the features that would be nice to have later. Separating the two is the single most effective way to control cost and time to launch.
4. Share examples
Links to products you like (or dislike) and a sentence on why are extremely helpful. They communicate expectations about design and behaviour much faster than long descriptions.
5. Mention existing systems and data
Do you already use accounting software, a CRM, a booking tool or spreadsheets that the new product must work with? Is there existing data to migrate? Integrations are often where hidden complexity lives, so mention them early.
6. Be open about constraints
Share your target launch date, your budget range and any requirements such as supported languages, accessibility needs or industry regulations. A budget range is not a commitment; it helps the team propose an approach that fits rather than an idealised one.
7. Define what success looks like
How will you know the project worked? Fewer support calls, more online bookings, less time spent on manual data entry? A measurable goal keeps decisions focused throughout the project.
What you can leave out
You do not need to choose technologies, design a database or write detailed specifications. Those are part of the development team's job, and good teams will work them out with you during discovery.
A simple template
- Background: who you are and what the project is about
- Problem: what is not working today
- Users: who will use the product and how
- Must-have features and later features
- Examples: products you like and why
- Existing systems and data
- Constraints: timeline, budget range, languages, regulations
- Success: how you will measure the result
Even a one-page brief that covers these points will make your first conversation with a development team far more productive.
