Our methodology
From idea to production in 4 steps.
01
Scoping & Design
Kick-off and business workshops. Definition of the technical architecture, initial backlog setup (navigation, user stories) and a lean specifications document. Commitment on a financial estimate and a target timeline.
02
Development Sprints
Iterative development organised in 2-week sprints (ticket review → development → business validation). Regular demos at the end of each sprint to avoid tunnel effect, framed by a monthly steering committee for budget tracking.
03
UAT & Go Live
Internal testing campaign (QA) and a ticket system for bug resolution. Once qualified, deployment to production (final Go Live tests), code handover and user training.
04
Post-release Warranty
One-month warranty period after the Production Release. Commitment on precise SLAs for bug handling and resolution (e.g. critical: 4h / 0–2d, major: 8h / 3d, minor: 2d / 5d).
