Mobile applications / decision to delivery

Before you build an app, define what it must change.

Mobile app development starts with the business problem and user behavior. Technology becomes relevant only after the first version has a clear job and a measurable result.

Assess the idea first

Short answer

A strong process has six steps: diagnose the problem, validate the need, test a prototype, define MVP scope, select technology and measure behavior after launch. Skipping the first three usually increases the cost of every later change.

Process

Six decisions before the first sprint.

  1. 01

    Problem and outcome

    What must change for the user and the business?

  2. 02

    Evidence of need

    How do users solve the problem today and what does it cost?

  3. 03

    Prototype

    Is the flow understandable and does it lead to value?

  4. 04

    MVP scope

    What is the smallest complete process that enables the next decision?

  5. 05

    Technology

    Native, cross-platform or web, given the real constraints?

  6. 06

    Measurement

    How will we measure activation, value, retention and support cost?

Technology choice

Native, cross-platform or web?

FAQ

Common questions.

Where should mobile app development start?
Start with the user, problem and measurable outcome. Test the core flow with a prototype before defining the MVP and selecting technology.
How much does it cost to build a mobile app?
Cost depends on user flows, integrations, data quality, security and maintenance. A credible estimate needs at least an initial discovery and explicit assumptions.
Does an MVP have to be a complete mobile application?
No. An MVP must deliver one complete moment of value and produce evidence for the next decision. Some operations can remain manual initially.

Next step

Have a mobile app idea?

Before the backlog exists, let us validate the user, risk and smallest test that can justify further investment.
