A fractional software development team for your roadmap

Bring the right disciplines together
A software product needs different skills at different times. A maintenance task may need senior engineering judgement; a new workflow may need research and UX design; a wider change may require product management to keep priorities and decisions moving.
Our fractional team model gives you an agreed allocation from a small senior team, with the relevant disciplines brought into the work. It suits organisations that need continuing development and care for a product, but do not need or want to employ a full internal team for every role.
Agree the capacity and the responsibilities
We start with the application, the priorities and the people already involved. The engagement defines the team mix, available capacity, ownership of decisions and how work will be reviewed. A fractional allocation is a planned share of the team’s time, so priorities need to fit that capacity.
The scope can combine maintaining an existing system with new development. UX and product management support help ensure changes are understandable and worth building, while engineering considers reliability, integrations and future maintenance. Where AI is relevant, we can bring that experience into a defined feature or workflow.
We keep a shared backlog, discuss trade-offs and demonstrate completed work. Project management oversight helps coordinate dependencies and maintain communication. You can see what is being worked on, what needs a decision and what is outside the agreed allocation.
Experience across product design and engineering
Our work at Easol included Rails engineering, reusable interface components and collaboration with an existing product team. At LV=, research and iterative UX design supported a complex insurance journey in collaboration with the client’s design and development team.
These projects demonstrate the different capabilities available across Bit Zesty. The mix in your fractional team is agreed around your product, rather than assuming every discipline is required every week.
How is this different from a dedicated full-time team?
A fractional engagement provides an agreed share of capacity. It does not imply an exclusively assigned, full-time team or unlimited availability. We discuss expected work, review points and how additional needs would be handled before the engagement begins.
Can the team work with our engineers?
Yes. We agree boundaries and shared practices so work fits with your existing team. If you already manage delivery and only need an individual specialist, staff augmentation may be a simpler fit. Senior technology strategy can be scoped separately through our fractional CTO service.
