Transformation stalls on people and approvals.

We start in one domain, prove the change works where the business can feel it, then widen out from something already running in production.

Clients we've worked with

How we deliver

Four phases. The first can honestly end the engagement.

Diagnose

We audit the systems, the data and the constraints, and tell you the real problem.

You getA findings document and a risk register

Blueprint

Architecture, sequence and the metrics we agree to be judged on.

You getArchitecture decision records and a costed roadmap

Prove

One domain, delivered end to end, measured against the agreed number.

You getA working domain in production, with the metric reported

Scale

What worked spreads; what did not gets stopped rather than repeated.

You getA scaling plan and the operating model to run it

Selected work

Operations changed one domain at a time, each proved in production before the next was funded.

Questions we get asked

Where should a transformation programme start?

With one domain that has a named owner and a problem worth fixing. Breadth in the first phase is what kills these programmes: budget goes on coordination, nothing reaches production, and the case for continuing rests on a slide. Starting narrow gives you something running inside a quarter, and a working system is a far better argument for the next phase than a business case.

How is this different from hiring a consultancy?

The deliverable is running software. Strategy is part of it, but what you receive is a system your staff use, and the same team does both. That matters because a plan written by people who will never have to build it tends to underestimate exactly the parts that turn out to be hard.

Do we have to replace our legacy systems?

Usually less than you expect. The systems that feel oldest are often the ones quietly working; the constraint is more often an integration, a manual handoff or a reporting gap. We look for what is actually blocking the business before proposing replacement, because a rewrite spends a year buying back the position you already hold.

How long before we see anything?

The first domain should reach production inside a quarter, and if a plan cannot show something running by then it is usually too wide. Longer programmes are structured as a series of those, each one delivering on its own, so the value does not sit behind a single distant date.

What if our people do not adopt it?

Then the programme has failed, whatever the software does. Adoption is designed in from the start: we work with the people doing the job, keep the change small enough to learn in a day, and agree in advance what the old way stopping actually looks like. Where a workflow cannot survive contact with the people using it, better to find out in week three.

Can you work with the systems integrator we already have?

Yes, and it is common. The split usually falls between a partner running long-cycle platform work and us taking the parts that need to move faster or sit closer to the business. What matters is that ownership of each interface is written down, because unowned boundaries are where these programmes lose months.

How do you measure whether it worked?

Against something the business already tracks, agreed before the build starts. Cycle time, cost to serve, error rates, the volume of a manual process removed. We take the baseline first, which is the step most often skipped and the reason so many programmes cannot say afterwards whether they paid for themselves.

Why SDTC?

We change one part of the operation, prove it in production, then widen — so results arrive before the invoice.

We first heard about them from our ex-CEO after he met them at a convention in Tokyo. The price, team, and setup were exactly what we needed, and the results exceeded expectations. We not only got a better app than planned but also learned a lot about our product and processes. We're so satisfied that we're starting a second project with them and would recommend them to friends—and even foes.
