Change Management vs Change Control: Key Differences Explained
Change control is the formal process for approving and recording changes to a project's scope, schedule, cost or deliverables. Change management is the wider discipline of helping people and organisations adopt a change, so that the new way of working is actually used and the benefits are realised.
Key takeaways
- Change control protects baselines; change management protects benefits.
- Change control decides on changes to scope, time and cost.
- Change management helps people adopt new ways of working.
- Check which meaning people intend, especially in IT.
The short answer
Change control asks 'should we change the plan?' Change management asks 'how do we help people change how they work?' One protects the project's baselines; the other protects the project's benefits. Most projects that alter how people work need both.
Comparison table
| Change control | Change management | |
|---|---|---|
| Focus | Changes to the project itself | Changes to the organisation and its people |
| Main question | Should we accept this change to scope, time or cost? | How do we get people ready, willing and able to work differently? |
| Typical owner | Project manager, change control board | Sponsor, change manager, business leaders |
| Timing | During the project, whenever a request arises | From early planning until well after go-live |
| Key outputs | Change requests, impact analysis, change log | Stakeholder analysis, communication and training plans, adoption measures |
| Success measure | Controlled baselines and informed decisions | Adoption, usage and benefits achieved |
| Related practice | Configuration management | Stakeholder management and communication planning |
Example: a new expenses system
- Change control: midway through the project, finance asks to add mileage claims with map look-ups. The project manager raises a change request, estimates +£9,000 and +3 weeks, and the change control board approves it. The schedule and budget baselines are updated.
- Change management: 1,200 staff must stop using paper forms. The change team identifies affected groups, briefs line managers first, runs short training sessions, sets up a help channel, and tracks the share of claims submitted through the new system each week. Paper forms are withdrawn once usage passes an agreed level.
Common change management models
| Model | Core idea |
|---|---|
| Kotter's 8 steps | Build urgency and a guiding coalition, communicate a vision, remove barriers, create short-term wins and anchor the change in culture |
| ADKAR (Prosci) | Individuals move through awareness, desire, knowledge, ability and reinforcement |
| Lewin's model | Unfreeze current behaviour, make the change, then refreeze the new behaviour |
These models describe the people side of change. They sit alongside, not instead of, project controls.
A third meaning: IT change
In IT service management, 'change management' often means controlling changes to live systems: assessing risk, scheduling deployments and approving releases, sometimes through a change advisory board. This is closer to change control than to organisational change management. When people use the term, check which meaning they intend.
How the two work together
- Use change management analysis early to understand who is affected and how much.
- Feed adoption needs, such as training or phased rollout, into the scope and plan.
- Route any resulting scope, cost or schedule changes through change control.
- Report adoption measures alongside delivery measures in the project status report.
- Carry adoption activities beyond project closure where benefits depend on them.

Frequently asked questions
What is the difference between change management and change control?
Change control manages changes to the project's baselines; change management helps people adopt the change the project delivers.
Change control vs change management: is one part of the other?
They are separate disciplines. Change control is a project control process; change management is about people and organisational adoption. Both are often needed on the same project.
Change management vs change control: who is responsible for change management?
The sponsor and business leaders are usually accountable, often supported by a dedicated change manager and the project team.
Change management vs change control: who runs change control?
The project manager runs the process; decisions are made by the person or board with the relevant authority.
What role does a change control board play in change control and change management?
It belongs to change control: a change control board is a group that approves or rejects significant changes to a project's baselines. It plays no direct part in change management.
How does a change advisory board fit with change management and change control?
In IT service management, a change advisory board is a group that advises on and approves changes to live services. It is closer to change control than to people-focused change management.
Where does ADKAR fit in change management vs change control?
ADKAR belongs to change management. It is a model from Prosci describing five stages of individual change: awareness, desire, knowledge, ability and reinforcement.
Why do projects need both change control and change management?
Change control keeps the deliverable on track, but without change management the deliverable may be built correctly but not used as intended, so the expected benefits never appear.
Does a small project need change management and change control?
Change control can be light, such as the project manager and sponsor agreeing changes together. Change management is needed if the project changes how people work, though it may be as simple as a briefing, a short guide and a check on usage.
How do change management and change control relate to stakeholder management?
Change management overlaps with stakeholder management: stakeholder management covers everyone with an interest in the project, while change management focuses on those whose work or behaviour must change. Change control is a separate process for managing the project's baselines.
Change management vs change control: what is organisational change management?
The structured approach to moving an organisation and its people from current ways of working to new ones. It is the full form of the people-focused side of the comparison.
