How will an IT outsourcing company work with our existing IT team?

An IT outsourcing company usually works with an internal IT team through a co-managed arrangement: the two teams divide responsibilities, share relevant information and use agreed processes for support, security and technology decisions. The outsourced provider supplements internal capability rather than automatically replacing it, allowing the business to retain control of priorities while obtaining additional capacity or specialist knowledge.

The relationship starts with an operating model. Before work begins, both parties should document how the arrangement will function. This normally covers:

• which systems and services each team manages;
• who owns business and technology decisions;
• which team receives different types of support request;
• when an issue is escalated and to whom;
• who can approve changes, purchases and access;
• how incidents, risks and planned work are communicated; and
• how information is recorded and kept up to date.

A responsibility matrix can make these boundaries explicit. For example, the internal team might retain responsibility for understanding departmental requirements and approving priorities, while the outsourced team maintains particular technical platforms or provides additional expertise for complex work. The division should be based on capability and business need, not on an assumption that every task must sit entirely with one party.

Day-to-day requests need a defined route. Businesses should agree whether users contact the internal team first, submit requests through a shared service desk, or use separate routes for different services. A shared process is often preferable where both teams may need to investigate the same issue, because it reduces duplicate tickets and makes ownership visible. Each request should have a named owner, a current status and a clear next action, even when several people contribute to its resolution.

Escalation rules are equally important. A first-line issue may remain with the internal team, whereas a problem involving a complex network configuration, cloud environment, cyber security control or infrastructure fault may be passed to the outsourced provider. The internal team should know what information to include when escalating, such as affected users, recent changes, error details and business impact. This gives the receiving team enough context to investigate without repeatedly asking the same basic questions.

Internal knowledge remains central to the arrangement. The outsourced provider may understand a technical platform, but the internal team usually has deeper knowledge of the organisation’s processes, users, suppliers and operational priorities. That business context should be shared through agreed documentation and regular communication. Useful records include system diagrams, asset information, application owners, support contacts, configuration details, known issues and recovery procedures.

Documentation should be treated as a working operational record rather than a one-off handover document. Changes to systems, permissions, suppliers and configurations should be reflected in it. A clear record also prevents the relationship from becoming dependent on one employee or one external consultant’s memory.

Access should be designed around the work each team performs. The provider should receive only the permissions needed for its agreed responsibilities, with privileged access controlled and attributable to an individual. Internal and outsourced staff should use separate accounts where appropriate, and access should be reviewed when responsibilities change. The business should also agree how emergency access, approval, logging and removal of permissions are handled. These controls allow both teams to collaborate without creating unnecessary administrative or security exposure.

Planned changes require joint coordination. An internal team may understand the operational consequences of a proposed change, while the outsourced provider may assess its technical dependencies and implementation risks. Before work is authorised, both sides should consider affected users, testing, backups, rollback arrangements, communication and the person responsible for confirming success. Changes should be recorded so that later incidents can be linked to recent activity.

The same principle applies to projects. The business should identify a project owner, decision-makers, technical contributors and users who need to be consulted. The outsourced company can provide design input, implementation support or an independent technical view, while the internal team helps determine whether the proposed solution fits the organisation’s processes and future plans. At the end of a project, knowledge transfer and updated documentation should be treated as deliverables rather than optional extras.

Communication should operate at more than one level. Operational contact deals with individual requests, incidents and changes. More structured reviews can address recurring problems, security priorities, technology risks, capacity and upcoming business activity. These discussions are most useful when they result in recorded actions, owners and dates rather than becoming informal status updates. The format can be proportionate to the organisation, but responsibilities and decisions should remain traceable.

Internal staff should also be able to challenge recommendations and ask for the reasoning behind them. An outsourced provider’s role is not simply to implement every technical option it identifies. Recommendations should be considered against business requirements, risk, compatibility, internal capability and the likely effect on users. This helps the business make informed decisions while preserving the internal team’s role as a knowledgeable technology stakeholder.

A well-structured partnership avoids two common problems. The first is overlap, where both teams believe the other is handling an issue. The second is an artificial division, where each team refuses work that falls just outside its documented boundary. Clear ownership, sensible escalation and a willingness to collaborate reduce both risks. The arrangement should be reviewed when the business changes, new systems are introduced or the internal team’s skills and capacity develop.

For a small or medium-sized organisation, this model can provide access to broader IT, cyber security, cloud and connectivity expertise without removing the value of an established internal team. The most effective arrangement is one in which the internal team understands what the provider is responsible for, the provider understands the organisation’s priorities, and both work from the same accurate information.
