Team Extension
Principal engineers, architects and specialists who join your team in the roles it lacks.
The Team Has the Mandate but Not Every Role
A programme can have the mandate and the budget and still lack one role. That role may be an architect for a decision, an engineer for a platform or a specialist for one hard problem.
Hiring takes months. A specialist joins your team for the part of the work that needs it, and your own team keeps its delivery model.
What You Get
You get a named specialist who works inside your team, and the records your managers need to run the placement.
An Agreed Role Brief
The skills, seniority, start date and deliverables of the role, in writing.
Candidate Profiles You Interview
A short list of specialists who match the brief, with their experience and the role they would take.
An Onboarding Plan
Access, tools, the first month's work and the person who answers questions inside your team.
A Monthly Placement Report
What the specialist delivered, what changed and any risk to the placement.
How a Specialist Joins
The placement starts in four steps. You choose the person and direct the work.
Agree the Role Brief
We write the skills, the deliverables and the start date with you. You approve the brief. End: a role brief both sides can measure.
Interview and Choose
We shortlist specialists and you interview them. You decide who joins. End: a named specialist and an agreed start date.
Onboard to Your Team
The specialist gets the access, tools and context the role needs. Your manager agrees the first month's work. End: an onboarding record and a first task.
Review the Placement
Each month you review the work and the fit with our account contact. You decide whether to continue, change the role or end it. End: a written review and the next month's plan.
What We Need From You
The placement works when three responsibilities are clear.
Someone Who Owns the Role Brief
A manager who can describe the work and decide whether a candidate fits.
A Manager Who Directs the Work
The person the specialist reports to, with the authority to set tasks and review results.
Access Before the First Day
Accounts, repositories and tools ready when the specialist starts, with the security approvals your rules require.
Where Team Extension Fails
Three failures are common. Each has a control in the placement.
A Role Brief Nobody Can Measure
A vague brief attracts the wrong specialist. We write the deliverables and the first month's work before you interview.
A Specialist Left Without Context
Without access and a named contact, the first month is lost. The onboarding plan names both before the start date.
The Work Depends on One Person
A specialist can become the only person who knows a system. We record decisions in your tools and plan a handover before the placement ends.
What Good Looks Like
You can check these signals without asking us for a status report.
You Chose the Person
The specialist passed your interview against the role brief, and you made the decision.
The Work Is Visible in Your Tracker
Tasks, reviews and decisions sit in your tools, under your process.
The First Month Has a Written Review
You and the specialist record what was delivered, what was missing and what changes next.
A Replacement Is Planned, Not Improvised
If the fit fails, we name a replacement and a handover date before the placement ends.
Questions and Answers
Which roles can we embed?
Principal software engineers, solution and integration architects, AI and data engineers, ERP specialists, and QA, security and experience designers. The role brief names the one you need.
How is this different from a dedicated team?
A dedicated team is a managed, cross-functional team run by XSIS. In team extension, specialists join your existing team in named roles, from one specialist to a small group.
Do specialists work on site?
Yes. They work at your premises or remotely, including inside your offices when the environment requires it.
How does a placement start?
With a conversation about the role and a written role brief. You interview and choose the specialist, and we agree the start date, the access and the first month's work.
Start With a Conversation, Not a Contract.
Tell us what you need to build, connect or secure. An architect goes through it with you, then recommends where to start.
What Happens Next
Agreeing a Time
Our team emails you to agree a time for the session.
Pre-Consulting Session
A free 30-minute online pre-consulting session: we go through your goals, systems and constraints.
Readiness Review
In a free 48-hour Readiness Review, a Principal Architect checks your project against What we need before we start and recommends the track that fits.
Choosing the Track
Scope-ready projects receive a binding proposal within 3 to 5 business days. Concept-stage projects start with Discovery and Design. A live system that is failing, undocumented or needs integration starts with the Live System Review of 1 to 2 weeks. Discovery and Design and the Live System Review each have a fixed fee, quoted in the proposal.
