Change Management & Change Control

2 min readPublished 29 Jul 2026

"Change management" means two different things in delivery — and great PMs handle both. One protects the plan; the other makes the outcome stick.

1. Change control (managing changes to the project)

As soon as a plan is baselined, requests to alter scope, time or cost will arrive. Change control is the process that stops these becoming chaos:

Raise a change request (what, why, requested by).
Assess the impact on the Iron Triangle (scope, time, cost) and risk.
Decide — a Change Control Board (CCB) or the sponsor approves, rejects or defers.
Update the baseline and communicate. Change control doesn't block change — it makes it visible and deliberate, protecting the project from silent scope creep.

2. Organisational change management (making change stick)

Delivering the product is only half the job — people have to adopt it. Change management is the discipline of moving people from the current to the future state. Two widely used models:

ADKAR — individuals change in a sequence:

Awareness of the need to change, Desire to support it, Knowledge of how, Ability to do it, Reinforcement to sustain it. If adoption stalls, diagnose which step is missing.

Kotter's 8 Steps — for leading organisational change:

Create urgency, 2. Build a guiding coalition, 3. Form a vision, 4. Communicate the vision, 5. Remove barriers/empower action, 6. Generate short-term wins, 7. Sustain acceleration, 8. Anchor the change in the culture.

Why it matters

Most "failed" projects delivered the product but failed on adoption — people carried on the old way. Planning for the human side (communication, training, reinforcement) is what turns a delivered output into a realised benefit.

Put it to work

For a change you're delivering, run a quick ADKAR check — which step is weakest for your users? — and add actions to your communication plan to close the gap.

Interview Intelligence

How this topic actually shows up in interviews — and how to demonstrate you understand it.

Why employers ask about this

Employers want PMs who protect the plan AND drive adoption — both meanings of change come up in interviews.

Technical questions

How do you handle a change request mid-project?+

Log it, assess Iron-Triangle and risk impact, take it to the CCB/sponsor to decide, then update the baseline and communicate.

How do you ensure a change is actually adopted?+

Plan the people side with ADKAR/Kotter: build awareness and desire, provide knowledge and ability, and reinforce it.

Behavioural questions

Tell me about a time you delivered a change that people resisted.+

Use STAR: how you built awareness and desire, trained users, secured quick wins and reinforced the new way to make it stick.

Real-world scenarios

“A new system you delivered is live, but staff keep using the old process.”+

Expected answer: Diagnose with ADKAR (likely Desire or Reinforcement), add communication, training and incentives, and secure leadership sponsorship.

Frequently asked questions

What is the difference between change control and change management?

Change control manages changes to the project's scope/time/cost via change requests and a board; change management helps people adopt the change (ADKAR, Kotter).

What is ADKAR?

A change model — Awareness, Desire, Knowledge, Ability, Reinforcement — describing the steps an individual goes through to adopt change.

What is a Change Control Board?

A group (or the sponsor) that assesses and approves, rejects or defers change requests based on their impact on the project.
