What is change management?

To paraphrase a famous quote, three things in life are certain: death, taxes and organisational upheaval. Change is a constant factor in any business, whether it's driven by shifts in technology, digital transformation or changing market pressures.

However, changing your business can be a difficult and daunting task, and if you don't take steps to ensure it's handled well, a poorly-managed change can end up sinking a company. That's why having a solid change management strategy is so essential.

Change management, at its simplest, is the concept of having a pre-defined plan for how your organisation is going to move from one state to another, and appointing a dedicated team to coordinate the process. This ensures that you can complete the process with minimal disruption to your day-to-day business whilst keeping sight of the goals you want the change to accomplish.

The different models of change management

There a number of different schools of thought as to how best to approach a change management programme. There's no 'best' or 'right' way to conduct change management; it will vary from business to business, based on their specific needs, culture and organisation.

With that having been said, there are some approaches that are generally regarded as successful models for change management, devised by some of the world's top business academics: Kotter, Carnall and Lewin.

Kotter model

Professor John Paul Kotter of Harvard Business School devised an eight-step process for leading change. They are: creating a sense of urgency, building a guiding coalition, forming a strategic vision and initiatives, enlisting a volunteer army, enabling action by removing barriers, generating short-term wins, sustained acceleration, and instituting change.

Carnall model

Colin Carnall, associate dean and executive of programmes and professor of strategic management at Warwick Business School, proposes a model that centres on the role of the manager during the process of change.

In his book, Managing Change in Organizations, Carnall says that managers skilled in managing transitions will create an environment of creative risk-taking and help people learn as they implement change. In turn, this achieves change in the organisation.

Lewin model

Kurt Lewin, recognised as the founder of social psychology, developed a change model involving three steps: unfreezing, changing and refreezing. Unfreezing is about getting ready to change or move out of an organisation's comfort zone. Then comes the change or transition, where the changes needed are made. Refreezing is about creating stability once the changes have been made.

The process of change management

A generic change process includes steps such as assessment, preparation, planning, implementation, and sustaining change.

Assess find out what is needed to convert outputs into outcomes. Viable change depends on a clear assessment of the impact it will have on various parts of the organisation.

Prepare create a vision and gain support from the organisation and key stakeholders. There needs to be an emotional and rational case for change.

Plan this is the roadmap which identifies the start point, the route to be taken and the destination. It also defines activities and roles to manage and control change during the execution and control stage of the change project.

Implement here's the heart of the change process. This includes communicating the benefits of change, removing barriers, and coordinating activities that change how the business operates.

Sustaining change a successful change is one that sustains and benefits the business in the long term. Sustaining this beyond the life of the project entails measuring the benefits produced, evaluating performance, and rewarding behavioural changes. To sustain change, companies must embed the appropriate mindsets, practices, and behaviours at every level.
