02 /Timing
The right timeto build.
- 01 /
A key process runs on spreadsheets and email threads.
I turn it into an application that does the work in place of your teams.
- 02 /
Off-the-shelf software forces you to work around the way you operate.
I build the tool that fits your business and talks to your existing software.
- 03 /
Your existing application needs to evolve faster than it allows.
I take it over, document it and grow it without rewriting everything.
- 04 /
Your clients expect online access to your services.
I build the portal or API that opens it to them, securely.
These are normal stages in the life of a growing business.
03 /Method
The method.Four steps, approved by you.
Every step ends on what you approve, see or receive.
01 /
Scoping
Written scope, fixed price, criteria that say when it's done.
Nothing starts without your sign-off.
02 /
Design
Journeys, screens and architecture, designed with your users.
You approve the screens before the first line of code.
03 /
Development
Delivery batch by batch, automated deployments, security built in from the start.
Each batch is demonstrated on a real environment before sign-off.
04 /
Go-live
Documentation, access handover, onboarding session.
You are not dependent on me.
Drift monitoring
Throughout the project, four indicators stay visible. What is guaranteed is not the absence of drift. It is that drift shows while it can still be corrected.
- Budget spent
- Budget spent, set against what has actually been delivered. A widening gap is the earliest signal, and the only one visible before the invoice.
- Milestones met
- The announced date and the real one, for every milestone. A delay is reported when it is three days old, not three weeks.
- Out-of-scope requests
- Always priced and decided by you, never absorbed quietly: that is how a project drifts without anyone having chosen it.
- Incidents encountered
- Every incident that occurred during the project, its cause and the time it took to get back to normal.
