One of the most persistently underestimated dimensions of change management is the financial investment required to build genuine adoption. An insufficient budget for people-focused change activities is a leading cause of partial adoption, change fatigue, and failure to realise intended benefits.
Definition and Distinction
Budget sufficiency for adoption and usage refers to the adequacy of financial resources explicitly allocated to activities that enable people to understand, accept, and embed new behaviours, systems, or processes. This is distinct fromthe project implementation budget (which funds technical delivery, infrastructure, and project management), the training budget (a subset of the adoption budget focused specifically on skills development), and the communications budget.
A comprehensive adoption and usage budget should cover:
change management resourcing (change managers, change agents, and sponsors);
stakeholder engagement activities;
training design, development, and delivery;
change readiness assessments;
resistance management;
post-go-live reinforcement and coaching.
Why Budget Sufficiency Matters
Research by Prosci (2023) consistently demonstrates that projects with adequate change management resourcing and budget are significantly more likely to meet objectives, stay on schedule, and deliver intended benefits. The cost of insufficient adoption is not limited to immediate productivity loss at go-live; it extends to ongoing inefficiency, workaround behaviours, rework, and the eventual need for remediation programmes.
A common benchmark cited in change management literature is that change management activities should represent between 10% and 15% of the total project budget, though this varies significantly by project complexity, organisational size, and the magnitude of the behavioural change required (Anderson & Anderson, 2010). Projects requiring significant behavioural change—such as cultural transformation or major technology adoption—may require a proportionally greater investment.
Assessing Budget Sufficiency
Change managers should assess budget sufficiency by: calculating the scope of people-facing activities required (based on the size of the impacted population, the complexity of the change, and the duration of the adoption period); estimating the cost of these activities; and comparing this estimate to the budget actually allocated.
When assessing sufficiency in the tool, rate the budget as sufficient only when the allocated funds can demonstrably cover all planned adoption activities without compromising quality or coverage. A budget that funds communications and training but not readiness assessments or post-go-live reinforcement should be rated as partially sufficient at best.
Example of a well-rated scenario
The project has a total budget of $2.5 million. A dedicated change management budget of $320,000 has been approved, covering: a full-time change manager, a part-time change analyst, training design and development across three modules, four stakeholder workshops, and a six-week post-go-live coaching programme. This budget is rated as sufficient given the project's medium complexity and 500-person impacted population.
Common Pitfalls and How to Avoid Them
Treating change management as a cost to be minimised: Budget decisions that reduce change management resourcing to save project costs frequently increase the total cost of the initiative when adoption-related remediation is required post-go-live.
Conflating training budget with adoption budget: Training is one component of adoption. A project that allocates budget only for training courses but not for communications, readiness assessments, coaching, or reinforcement has not adequately funded the adoption journey.
Failing to flag budget insufficiency formally: Change managers who identify that the adoption budget is insufficient have a professional obligation to escalate this risk formally through the project governance structure. Informal concern without formal escalation does not constitute risk management.
Not revisiting budget adequacy as scope changes: Project scope changes can significantly affect the size and complexity of the adoption effort. Budget sufficiency should be reassessed whenever the scope, timeline, or impacted population changes materially.
