Feature Flag Implementation in Exeter
Introducing feature flags for Exeter engineering teams, with the discipline that makes them worth having. Every flag doubles the paths through a piece of code, and a system accumulating them without a removal habit becomes harder to reason about than the release process the flags were introduced to improve.
Why this comes up
The problem
There are ninety flags in the codebase, forty are permanently on, and nobody knows what the rest control.
What you get
What we deliver
- Flag types distinguished — release, experiment, operational and permanent configuration
- Removal built into the process, with an owner and an expiry against each temporary flag
- Naming and structure agreed so a flag's purpose is evident from its name
- Testing strategy defined, since combinations multiply faster than test cases
- A kill switch capability established for the things worth turning off in an incident
- Flag state made visible, so support and engineering see what a user is experiencing

Feature Flag Implementation in Exeter — common questions
- Why is removal the hard part?
- Because nothing forces it. Once a feature is fully released the flag is harmless in the short term and permanent in practice, and a codebase carrying dozens of them has conditional branches nobody dares remove because nobody remembers what they were for.
- Do flags complicate testing?
- Substantially, and it needs a stated approach. Ten independent flags describe a thousand possible states, so teams test the combinations that actually occur — usually current production plus the next release state — rather than pretending to cover all of them.
- What is a kill switch worth?
- A great deal during an incident. Being able to disable a payment provider, a recommendation engine or a heavy report without deploying turns a serious outage into a degraded feature, which is frequently the single strongest argument for the investment.
- Should support see flag states?
- Yes, because otherwise reported problems are irreproducible. A customer experiencing a different variant from the one an engineer sees produces a bug nobody can replicate, and surfacing which flags apply to that account resolves it in seconds rather than hours.
- Do you work with businesses across Devon?
- Yes. We are based in Leicester, United Kingdom and work with clients throughout South West, including Exeter and the surrounding Devon area. Most collaboration happens remotely, and we travel for kick-offs and key milestones.
- What kind of Exeter businesses do you usually work with?
- Field service scheduling and routing for businesses covering a wide rural patch, plus professional services systems. Beyond that we work across Higher Education, Professional Services, Healthcare, Retail and Environmental Science.
- Do you cover the areas around Exeter?
- Yes — we work throughout South West, including Plymouth, Truro, Bristol. Exeter is an urban area of roughly 130,000+, and we take on work across the wider Devon region rather than the city boundary alone.
