- 03
Tracking

An approach tailored to your context.
A customer area. Shared progress tracking.

How we support youFrom a business need to a usable web application.

✓A useful scope and success criteria.
Simple journeys

04Journey testing, error monitoring, documentation and handover to keep the product running.

05Key scenarios, errors and exceptions are examined before the next phase.
✓Visible approvals and discrepancies addressed.
Launch and learn
06Launch, monitoring and early feedback prepare future releases.
✓A shared development path.
Making the right choicesWhen does custom development make sense?
The choice depends on your users’ needs, the existing system and the cost of future development. We make the trade-offs clear before development begins.
Configure an existing tool
01An off-the-shelf product may be enough if its journeys, permissions and integrations match the way you work.
✓First assess what already meets the need.
Build your application
02Custom development makes sense when rules, integrations or the experience become decisive factors.
✓Invest in what is truly specific to your organisation.
