Here's a simple rule that's saved us more times than I can count: every two weeks, the client sees working software. Not wireframes. Not slide decks. Not a demo on a developer's machine. Real, working software they can click on and react to. It sounds obvious. It's the single most powerful habit in delivery.
Why Two Weeks
Two weeks is long enough to build something meaningful. Short enough that you can't drift far off course. It's the tightest feedback loop you can run without turning delivery into a performance.
When a client sees working software fortnightly, three things happen.
Misunderstandings surface early. The gap between what a client asks for and what a developer builds is always wider than both parties think. Words are ambiguous. Requirements are interpreted. The only way to close that gap is to show the work. Two weeks of misalignment is recoverable. Two months isn't.
Priorities self-correct. When clients see the system taking shape, they naturally reprioritise. "Actually, that screen I said was critical? It's fine. But this workflow over here, that needs to be different." This is healthy. It's the product getting better. But it only happens if the client can see and touch the work.
Trust compounds. Every two-week demo that works as expected deposits trust. The client sees progress. They see their feedback reflected. They see a team that delivers. That trust makes hard conversations easier when they inevitably come.
The Objections
"We're not ready to show anything yet." You should be. If after two weeks of work there's nothing demonstrable, the scope is wrong or the approach is wrong. Break the work down further.
"The client won't understand a rough version." Frame it properly. "This is two weeks of work. Here's what we focused on. Here's what's coming next." Clients are smart. They can handle work-in-progress if you set expectations.
"We'll spend all our time preparing demos instead of building." If the demo takes more than an hour to prepare, you're over-engineering it. Deploy. Walk through it. Get feedback. Move on.
"Our approval process takes longer than two weeks." That's a problem worth solving. A two-week demo cycle doesn't require formal sign-off every fortnight. It requires the client to look at the work, give feedback, and confirm direction. The governance process can run on a different cadence.
The Real Test
If you're running an enterprise project and the client hasn't seen working software in four weeks, stop and ask why. The answer will tell you something important about how the project is really going.
The number one predictor of project success we've seen at IDESIGN isn't the technology stack, the budget, or the methodology. It's how often the client sees the work.
Every two weeks. No exceptions. Show the work, get the feedback, keep building. That's how great software gets made.
