Fast Flyer Transport: launched in 10 days

A transport operator's app shipped four days inside the sprint window. What made it possible, and why we still quote fourteen days rather than ten.

The short answer

Fast Flyer Transport's app went live on day ten of a fourteen-day sprint. The managing director's words: "Launched in 10 days! You guys surpassed our expectations."

Why it finished early

Not because we worked faster. Because the client did three things that any client can do.

What made ten days possible

  • One decision-maker, availableThe MD reviewed and approved without a committee.
  • Design signed off on scheduleThis is the single biggest determinant of whether a sprint finishes early or late.
  • Content ready at kick-offBranding and operational detail were there on day one, not chased on day six.

None of that is about engineering. It is about removing the waiting.

Why we still say fourteen days

Because we would rather beat a promise than miss one.

Most sprints use the full fortnight, and a few things outside our control can absorb the slack: App Store review timing, a slow reply during a busy week, a piece of content that arrives late. Quoting ten days and delivering fourteen would be worse for you than quoting fourteen and delivering ten.

What happened

Launched in 10 days! You guys surpassed our expectations. You augmented our initial ideas and made into a truly wonderful app. I would love to work with the team more often.

The phrase in that quote we pay most attention to is "augmented our initial ideas". Day one is a conversation, not a dictation. A client arrives with an idea, and the useful thing a studio does is make it sharper and smaller before building it.

What we would tell you honestly

Ten days is not a promise, and you should not choose a supplier on the basis of somebody else's best case. Fourteen is the commitment. Anything better is a consequence of how prepared you are, not of how hard we push.
