From App Idea to MVP: What Should You Build First?

Build the smallest release that lets a particular group of people complete a useful task and gives you evidence about whether they want the product. Start by defining that task. A list of attractive features can wait until you know what the first version needs to prove.

For a booking product, the useful result might be a confirmed reservation. For an internal tool, it could be a request that reaches the right person with enough detail to act on. The first release needs to work from the user’s starting point through to that result.

The following approach will help you turn an app idea into an MVP scope you can discuss with a development team. It includes a worked example and a short brief you can use before asking for an estimate.

Decide what your MVP needs to teach you

A minimum viable product, or MVP, is an early version used to learn from actual customer behaviour. Agile Alliance’s explanation emphasises that learning purpose and warns against treating “minimum” as a reason to deliver something too incomplete to assess.

Write down the assumption that could make the idea fail. Do customers have enough of a problem to change how they work? Will they pay for the proposed service? Can the product access the information needed to deliver its result?

Different assumptions call for different tests. A prototype can help you observe whether someone understands a booking flow. A manually supported trial can help you learn whether people will submit requests and return. Checking an essential supplier connection may need a technical investigation before either.

Choose one decision the evidence will inform. For example: “After the trial, we need to decide whether to build direct booking confirmation or keep an assisted request service.” That is more useful than collecting feedback without knowing what you will do with it.

Choose an early user you can reach

“Small businesses” is usually too broad for a first product brief. A sole trader taking bookings by phone works differently from a multi-site company with a reception team. Choose a group whose current process you can understand and whose members you can involve in a trial.

Talk through recent examples of the problem. Ask what happened, which tools they used and how they dealt with the awkward parts. A person saying they like an app idea gives you less detail than watching them search their inbox for an unconfirmed booking.

Record where you can recruit the first users and what participation will involve. If you cannot reach the people you hope to serve, resolve that before spending heavily on their proposed product.

Map one complete task before choosing features

Describe the user’s journey in ordinary language. Where do they begin? What information must they provide? What should they receive when the task is finished? Include any work your own team must do behind the scenes.

Walk through a cancellation, an incorrect submission and a failed notification. These cases help reveal missing parts of the journey. A polished request screen is not enough if nobody can find the request or tell the customer what happens next.

Then identify which steps need software for the trial. You might be able to check availability manually while testing demand for a service. Be clear about that operating arrangement and how long the user should expect to wait. A request awaiting review must not appear as a confirmed booking.

The GOV.UK Service Manual’s alpha guidance offers a useful planning principle: test the assumptions that pose the greatest risk, including essential technology connections. A commercial app can apply that principle without adopting the government’s whole delivery process.

Choose MVP features by the job they support

For every proposed feature, name the part of the first task it supports and what you would learn from it. If the link is weak, move the feature to a later discussion. Keep essential operating requirements visible even when users never see them on a screen.

These are choices to assess, rather than universal shortcuts. Manual handling has a cost and may be unsuitable for the information or transaction involved. Record it in the scope so a low development estimate does not hide an impractical service model.

A worked example: an equipment-hire request app

Illustrative product: a local equipment-hire business wants customers to request items without a long phone exchange. It first needs to learn whether customers can provide enough information online for staff to assess the request.

The pilot could let a customer choose an equipment type, enter dates and delivery details, submit a request and receive a reference. Staff would review the request in a queue, check availability and respond with a quote or an alternative. The customer would see that availability and pricing require confirmation.

For this test, automatic route planning, a loyalty scheme and a marketplace for other suppliers can stay on the roadmap. A way to correct a request and contact the team belongs in the initial journey. So does an operational view that prevents requests from being lost.

The trial would record whether submitted requests are complete, which questions need clarification and how much handling each request requires. It would also follow whether customers proceed after receiving a quote. Those observations can inform the next scope: improve the request form, add a supported availability connection or reconsider the offer.

Keep the foundations and the roadmap in view

A focused first release still needs suitable access controls, dependable storage and a way to recover from failures. Plan for accessibility, support and the handling of the information you collect. The detail should reflect the product’s actual scope and risk.

Some future choices affect the design now. A product serving separate businesses may need a clear way to keep their records apart from the outset. Different staff roles may require permissions that are hard to add after every user has been given the same access.

This is where experienced product management helps. Keep a roadmap that explains likely future needs and dependencies, while agreeing which of them justify work in the first release. A large backlog alone does not provide that direction.

Prepare a brief a team can estimate

You do not need to arrive with every screen designed. A useful brief gives the team enough information to question the scope and identify what needs investigation.

• Early users: who they are, how they work today and how you will involve them.
• First useful task: the starting point, intended result and main steps.
• Learning goal: what the trial needs to show and which decision follows.
• Operating model: what software will do, what staff will handle and who supports users.
• Dependencies: systems, data access, payments and permissions that could affect delivery.
• Constraints: available budget, meaningful deadlines and requirements that cannot be deferred.

Ask the development team to separate confirmed scope from assumptions. If a connection has not been checked, an estimate should show that uncertainty and the work needed to resolve it. Agree how scope changes and post-launch support will be handled.

Plan the decision after the trial

Choose evidence that relates to the question you started with. Registration totals may say little if users never complete the task. Look at completed journeys, repeat use and the reasons people stop. For a paid offer, track the relevant purchase or commitment as well.

Combine those observations with conversations about what happened. A user may abandon the app because the value is weak, because one instruction is unclear or because a response took too long. Each explanation points to different work.

At the end of the trial, decide what to keep, change or stop. Use that decision to shape the next release. Grendigital’s MVP and product development service can help you work through the first scope and the product decisions behind it.
