Short answer
A focused web or mobile application typically takes 6 to 14 weeks from kickoff to launch. Larger systems are delivered in phases, with the first useful release often within a few months. Scope, integrations, decision speed and data migration have the biggest effect on timelines.
Typical timelines
Every project is different, but at Mohteknologies most web and mobile builds run 6 to 14 weeks from kickoff to launch. Here is roughly how that breaks down:
- Discovery: one to three weeks, depending on how many people and systems are involved.
- Design: one to three weeks, often overlapping with the start of development.
- Development and testing: the bulk of the time, delivered in one- to two-week iterations.
- Launch preparation: about a week for data migration, training and production setup.
Larger platforms, such as multi-tenant SaaS products or systems with many integrations, are delivered in phases. The aim is always to get a first useful version live as early as possible.
What makes projects take longer
- Unclear or changing scope without re-prioritisation
- Slow decisions or feedback between iterations
- Integrations with poorly documented or legacy systems
- Messy data that needs significant cleaning before migration
- App store reviews for mobile apps, which add time outside the team's control
How to move faster without cutting corners
- Define a first release around one core workflow.
- Nominate one decision-maker who is available every week.
- Give early access to systems, data and accounts.
- Use proven technologies rather than experimenting during the project.
