# Building an Internal Operations Function or Using Operations as a Service

When an organisation recognises that it needs stronger operational capability, the instinct is usually to recruit. An operations manager or head of operations is appointed, with the expectation that one person will absorb the coordination, improvement work, and day-to-day issues that have been landing with the leadership team.

That decision is often made before all the options are on the table. The alternatives leaders often consider are a contractor or a consultancy, brought in for a defined piece of work. A third option, Operations as a Service, is often overlooked. This article compares building that capability internally with using Operations as a Service, and explains when each one, or a combination of the two, fits best.

---

## What is Operations as a Service?

Operations as a Service is an ongoing operational function that works alongside an organisation’s leadership team, provided by an experienced external team rather than built in-house. It brings together three layers: strategic operations leadership, embedded operational management, and specialist capability in areas such as process design, systems architecture, and governance. The work is directed by an Operational Roadmap grounded in the organisation’s goals, current conditions, and priorities. Ownership of decisions and outcomes stays with the organisation’s leadership.

## What does an operations function need to provide?

An effective operations function provides three kinds of capability, and growing organisations often need all three at once:

- Leadership, setting operational strategy, priorities, and the operating model
- Management, keeping priorities moving, coordinating across teams, and handling issues
- Specialist delivery, in areas such as process design, systems architecture, governance, and implementation

A single appointment rarely covers all three. A strong operations manager may run the day-to-day well and still need senior direction on the operating model, or specialist support when a systems change or restructure arrives. Comparing the options fairly means accounting for the whole function, whichever route provides it.

## Six factors to compare

Each factor applies to both routes. Weighing them together gives a more reliable answer than any one of them alone.

### 1. Leadership

Someone needs the seniority to set operational priorities and connect them to the organisation’s strategy. Internally, that means a senior appointment, or existing leaders taking it on alongside their current roles. Operations as a Service includes strategic operations leadership within the function.

### 2. Management

Day-to-day operational management is often the layer organisations recruit for first. Operations as a Service includes embedded operational management. On either route, the test is whether the role will have the authority and support to act, or whether decisions will still return to the leadership team.

### 3. Specialist delivery

Operational problems often cross process, systems, governance, and change. An internal function either recruits these skills, buys them in project by project, or asks generalists to cover them. Operations as a Service provides access to them within one function, according to agreed priorities.

### 4. Organisational knowledge and continuity

Knowledge built inside the organisation is a lasting asset, and an internal team accumulates it over time. The risk is that it becomes concentrated in a few people. Whichever route is chosen, knowledge should be documented, owned, and usable by the organisation, so that continuity does not depend on any individual or provider.

### 5. Time to effectiveness

Building a function takes time before it delivers fully, because the organisation must work through these stages:

- Defining the capability required
- Recruiting and onboarding the right people
- Establishing responsibilities and ways of working
- Building organisational knowledge

The operational problems continue throughout that period. An external function begins with established ways of working, although it still needs time to understand the organisation.

### 6. Cost and flexibility

Internal capability carries fixed employment and management costs, which suit a stable, predictable need. A service turns much of that into an ongoing subscription that can be scaled as needs change.

**Comparing cost honestly.** List the full cost of each route. For an internal function, that means recruitment, salaries and on-costs, management time, specialist support bought in separately, and the period before the function is effective. For a service, it means the subscription. On both sides, include the cost of implementing and maintaining changes, and treat released capacity as a cash saving only when that time is redeployed or the cost removed.

No single factor settles the decision. An organisation with a clear, stable need may find an internal team the better long-term investment, while one facing connected problems across several areas may value breadth and pace more highly. The evidence that matters most is a clear view of the capability the next stage requires, and of which gaps recur rather than arise once.

## Which model fits which situation

An internal function often fits best when the operational need is well defined and stable, the organisation can recruit and manage the right people, and there is time to build the function before it is relied upon.

Operations as a Service often fits when the need recurs across several connected areas, senior leaders are carrying too much operational responsibility, and the organisation needs experienced capability sooner than it could recruit it. [Operations as a Service](https://www.thesystemslab.io/operations-as-a-service) brings strategic operations leadership, operational management, and specialist capability together in one team, directed by an Operational Roadmap.

A combination can also work well. An internal operations lead may be supported by the wider function, or an external team may build processes and knowledge that later move in-house. Where the need is limited to one specific piece of work, such as replacing a system or improving a single process, a one-off project may be enough, and an ongoing function may not be needed.

## What stays with the organisation either way

Whichever route is chosen, some responsibilities remain with the organisation’s leadership:

- Executive sponsorship and direction
- Decision authority and clear escalation routes
- Access to the people, information, and systems involved
- Staff time to take part in change
- Human accountability for outcomes, including AI-enabled work

An internal appointment without these conditions struggles in the same way an external team would. Agreeing them in advance is often the most useful preparation for either option.

## What leaders need to decide before choosing

The choice between building an internal operations function and using Operations as a Service is a decision about capability, timing, and risk. Comparing equivalent capability on both sides gives leaders a fair basis for making it.

Before recruiting or subscribing, define the capability the next stage requires, the gaps that keep recurring, and the authority any function will need. With that clarity, the right model, or the right combination, becomes far easier to see.

If your organisation is weighing how to build the operational capability it needs next, an initial conversation can clarify the need and whether Operations as a Service is the right fit.
