Enterprise software development consulting

Most of what determines the long-run cost of an enterprise system is decided in its first months: where component boundaries fall, who owns which data, how services communicate, and what the team is expected to operate. Those decisions are cheap to make and expensive to reverse.

Our engagement is to take them deliberately and record why, then to hold delivery to them as the system grows. That means setting design constraints that survive contact with delivery pressure, and defining what quality means precisely enough to automate — a definition of done that cannot be enforced by a pipeline is an aspiration.

Where the wider estate is in question rather than one system, that is enterprise architecture consulting. Where the constraint is the platform the software runs on, see cloud consulting.

Custom development is justified when a process is a genuine differentiator, or when no product fits without customisation that would cost more than building. Where a package fits, we say so — build-versus-buy advice that always concludes in favour of building is sales, not counsel.

When building is right, we set the domain model and component boundaries first, because those determine how much the second year of development costs relative to the first.

Mobile in an enterprise context is mostly a distributed systems problem. The device is an unreliable, intermittently connected node with its own data lifecycle, so offline behaviour, conflict resolution and sync are architectural decisions rather than features.

Cross-platform delivery is the default where the interface is largely shared; native is right where deep platform integration or specific hardware access dominates. We make that call per application, on the requirements rather than on preference.

Microservices buy independent deployability at the cost of operational complexity and distributed failure. That trade is worth making when teams genuinely need to release independently, and is a poor default otherwise.

Most failed microservice estates were split along team structure rather than data ownership, producing services that must be released together — the operational cost of distribution without the independence. We draw boundaries from the domain model, using domain-driven design where the domain is complex enough to warrant it.

Cloud-native describes how an application is built, not where it runs. Applications lifted to a cloud platform without changing their assumptions about state, startup time and local disk gain a rental cost and little else.

We design for horizontal scaling, externalised configuration, disposability and health signalling, and we are explicit about which managed services are being adopted and what switching away from them would cost. Platform-level decisions are covered in cloud consulting.

Once a system spans processes, partial failure becomes normal operation rather than an exception. Most production incidents in distributed estates trace back to failure modes that were never designed for: retry storms, cascading timeouts, and clients that treat a slow dependency as an available one.

We design timeout budgets, retry policy with backoff and jitter, circuit breaking and bulkheads as part of the architecture, and we state the consistency model each workflow actually requires rather than defaulting to the strongest one available.

Controls that live outside the pipeline are applied inconsistently and discovered late. Controls inside it are applied to every change by construction.

We integrate static analysis, dependency and image scanning, infrastructure policy checks and secret detection into delivery, and tune thresholds deliberately. A gate that produces noise is routinely overridden, which is worse than no gate because it also produces false assurance.

Governance fails in two directions. Too little, and every team selects its own stack, producing an estate nobody can staff. Too much, and approval boards become a queue teams route around.

The workable version is a small set of defaults with a documented exception path: a technology position stating what is standard, what is permitted with justification, and what is being retired — plus decision records so future teams inherit the reasoning rather than only the outcome.

Most struggling test suites are slow and brittle because the balance is wrong: too many end-to-end tests asserting behaviour that unit tests could cover faster and more precisely. The result is a suite teams distrust and eventually bypass.

We set the balance deliberately — fast tests for logic, contract tests at service boundaries, and a small end-to-end set covering journeys that genuinely must work. Non-functional testing is scheduled against stated requirements rather than performed once before launch.

Performance work without measurement is guesswork, and the bottleneck is rarely where intuition places it. In most enterprise systems it is data access — query patterns, N+1 access, or a schema that forces the application to compensate.

We start from stated requirements — throughput, latency percentiles, concurrency — because a system cannot be designed for performance that nobody has quantified. Caching is applied where the invalidation strategy is understood, and not before.
