Every year, supply chain organisations invest heavily in new planning systems. Advanced planning and scheduling tools, integrated ERP platforms, demand management software. The business case is built. The vendor is selected. The project is launched. And then, somewhere between go-live and the expected return on investment, something goes wrong.
Not with the technology. With the people who are supposed to use it.
The pattern is well-documented and persistent. According to McKinsey, the digital transformation success rate has remained stagnant at around 30% for fifteen years. Gartner estimates that more than 75% of ERP implementations fail to fully meet their original business case goals. These are not primarily failures of software. They are failures of adoption, and adoption is a human problem, not a technical one.
The Implementation Illusion
There is a particular kind of organisational optimism that surrounds system implementations. The new platform will standardise processes. The dashboards will make decisions clearer. The data will finally flow in the right direction. These outcomes are entirely achievable, but they depend on a condition that project plans consistently underestimate: people must actually change the way they work.
McKinsey research on large-scale IT projects, conducted alongside the University of Oxford, found that such projects deliver on average 56% less value than originally predicted. The technology performs as specified. The shortfall lies in the human system surrounding it: the planners who revert to spreadsheets because the new tool feels unfamiliar, the managers who bypass the process because the old way is faster, the teams who were never adequately prepared for what the change would require of them.
70%+
of digital transformations fail to deliver their expected outcomes, according to McKinsey. The primary cause is not technology. It is people and process adoption.
In supply chain planning specifically, this plays out in recognisable ways. A recent industry survey found that 37% of organisations using an advanced planning system say the technology has not been adopted widely enough across the business. Another four in ten report that their system still requires too many manual workarounds. In both cases, the system is live. The investment has been made. But the value remains locked.
Why Adoption Fails
Understanding why adoption fails requires looking beyond the project plan. Most implementation programmes invest heavily in system configuration, data migration, and user acceptance testing. These are necessary. But they address the technical side of the change, not the human side.
Prosci, the global authority on change management research, identifies a clear pattern across thousands of projects. When organisations treat change management as a communication exercise, telling people what is changing rather than preparing them for how to change, adoption rates suffer and project objectives are missed. Their research is unambiguous:
"88% of projects with excellent change management met or exceeded their objectives. Just 13% of projects with poor change management achieved the same."
Prosci Best Practices in Change Management research
That gap, 88% versus 13%, is not explained by the quality of the technology. It is explained by the quality of preparation, support, and leadership given to the people being asked to change.
The failure modes are consistent across organisations and sectors:
Planning teams are trained on how to operate the system, but not on why the new process is better or what good output looks like in the new environment. Resistance is treated as a communication problem to be managed rather than a signal that people have not yet been equipped to succeed. Leadership endorsement is given at launch but withdrawn when the project gets hard, leaving frontline planners without visible sponsorship. Success is measured at go-live rather than at adoption, meaning the organisation declares victory before the real work has begun.
The Role of Leadership in Making Change Stick
Prosci research has consistently identified active and visible sponsorship as the single most important factor in change success. Since 1998, having a leader who visibly champions the change and models the desired behaviours has topped the list of change management success factors. The data is equally clear on the downside: projects with highly ineffective sponsors achieve their objectives just 27% of the time, compared to 79% for projects with highly effective ones.
For supply chain directors and VPs leading a planning system implementation, this is a direct responsibility, not something to delegate to a project manager or change consultant. The questions worth asking are practical ones:
Are you visibly using the new system yourself, or continuing to rely on the outputs others extract from it? When planners raise concerns about the new process, do they receive support and clarity, or are they told to work it out? Is the organisation measuring adoption and capability growth post-go-live, or only tracking whether the system is technically operational? Have you communicated not just what is changing, but why it matters and what success will look like for each part of the team?

These are not soft questions. They are the variables that most directly determine whether the investment in a new planning system delivers a return.
Building Genuine Capability, Not Just Compliance
The distinction between compliance and capability is critical in planning system implementations. Compliance means people use the system because they have to. Capability means people use it well because they understand it, trust it, and can challenge it when something looks wrong.
Organisations that achieve genuine capability after a system implementation share a common approach. They invest in structured capability building that goes beyond feature training. They create space for planners to develop judgement about the new environment, not just familiarity with the interface. They treat the period after go-live not as wind-down, but as the most important phase of the project.
McKinsey's analysis of supply chain planning teams reinforces this point. Their research found that average capability scores across organisations have remained largely flat for years, not because digital tools are unavailable, but because the investment in human capability has not kept pace with the investment in technology. The tools change. The people do not.
Closing that gap requires treating capability building as a core programme deliverable, with its own timeline, resources, and success metrics, not as an afterthought scheduled for the final weeks before go-live.
What Effective Change Enablement Looks Like in Practice
For supply chain planning implementations specifically, the organisations that succeed with change management tend to do several things differently from those that struggle.
They start change management before the system is selected, not after it is configured. Engaging planning teams in the design and testing process builds understanding and reduces resistance at go-live, because the people who will use the system have already shaped it.
They define adoption metrics from the outset. What does good look like six months after go-live? How will the organisation know whether planners are using the system in the way it was designed? These questions need answers before implementation begins, not after problems emerge.
They invest in the middle layer. Senior sponsors and frontline users tend to receive the most attention in change programmes. The planning managers and team leads sitting between them are often underserved, yet they are the people whose daily behaviour most directly shapes whether new processes stick.
They keep the conversation going. The most effective change programmes do not end at go-live. They establish regular check-ins, create forums for planners to raise difficulties without blame, and use adoption data to identify where additional support is needed.
The Grange Perspective
At Grange, we work with supply chain planning functions to close the gap between system implementation and real organisational performance. Our approach combines deep planning expertise with structured change enablement, ensuring that new tools, processes, and behaviours take root and deliver lasting value.
