The design pair and the build team, answered in full.

Three forward-deployed practitioners: an Agentic Lead who owns the operating model and decision rights, a Forward-Deployed Engineer who builds and ships inside your estate, and an Adoption Lead who owns the part that usually fails, getting people to actually work the new way. James Rooney provides partner oversight on every engagement. Everyone on the team is someone he has already delivered alongside, screened to BS7858 standard before any client access, and the people on your engagement are not substituted without your written agreement.

An interim agentic lead is a senior practitioner who runs an organisation's agentic delivery from inside its management structure for a defined period rather than as a permanent employee. At Tenhaw the role sits at the front of the Agentic Build Team: real decision rights, a real reporting line, accountability for a monthly production increment, and a dated exit with the capability owned by your permanent team. James Rooney is embedded in that role on a live engagement inside a London specialty insurance business, which is where the method on this site is being run in anger.

Not from this rung. A build team is three people because shipping needs three: someone holding delivery, someone building, and someone owning adoption. If what you want is one senior person holding delivery, governance and supplier management while other people build, that is programme and delivery management at £18,000 to £35,000 a month, and it can be run fractionally from around three days a week. We would rather point you at the cheaper rung than sell you two people you do not need.

Engagements are structured around a monthly production increment rather than a distant go-live, so you can judge the work on evidence within the first thirty days. Each month the team commits to something measurable reaching production and reports against it; a month with nothing in production is reported as a failed month. This is the commitment we ask to be held to from month one.

The exit is designed at kickoff rather than negotiated at the end. The team pair-programs with your engineers throughout, recruiting your permanent team is an explicit deliverable, and the final sixty days are a documented handover with a decreasing-involvement taper. On a recent engagement, a client engineer who paired on a two-week build finished it 70% confident they could run the process unaided.

£70,000–£85,000 per month for a team of three under partner oversight, typically on a 6–12 month engagement. That is comparable to a mid-sized consultancy engagement team, but resolves to three senior practitioners accountable for the outcome rather than a pyramid of juniors.
