A UK technology provider should be shortlisted only when responsibilities, service boundaries, security operations, cloud and infrastructure ownership, escalation, evidence, commercial exclusions and transition arrangements are explicit. This guide helps procurement, IT and leadership compare managed IT, Microsoft cloud and cybersecurity providers on those decision points.
Responsibility stack
A documented responsibility matrix should define customer, provider and third-party ownership across systems, service desk, monitoring, change, incidents, continuity, approvals, reporting and exit.
Provider comparison
Request service boundaries, an onboarding and transition plan, an architecture and dependency map, sample reporting, security and incident processes, service levels, exclusions, pricing assumptions and validated references where available.
| Criteria | Question | Evidence |
|---|---|---|
| Responsibility | Which services, systems, decisions and escalations does the provider own? | A responsibility matrix, service boundaries, escalation paths, exclusions and exit ownership. |
| Security operations | How are alerts, vulnerabilities and incidents prioritised and closed? | A sample alert workflow, severity model, response path, remediation evidence and reporting pack. |
| Architecture | Can the provider explain the current state, target architecture and transition risks? | A discovery record, dependency map, reference architecture, migration plan and rollback approach. |
| Commercial clarity | What is included, excluded, chargeable and dependent on third parties? | A priced scope, assumptions, service levels, onboarding plan, optional work and termination terms. |
Weighted decision graph
Weight security and resilience, operating fit, governance evidence and commercial clarity above feature count, presentation quality and unsupported sales claims.
Provider shortlist briefing
Use one evidence request, score responsibilities, transition dependencies and risks consistently, and remove providers that cannot define ownership, exclusions and escalation before contract.
Use one documented comparison model across procurement, IT, security and leadership so the final decision can be explained and governed.
