Most ERP and digital planning projects are judged on go-live day. They shouldn't be. The decisions, behaviours, and capabilities that determine whether a transformation delivers value are locked in long before that date.
The data is unambiguous. According to Gartner, more than 70% of ERP implementations fail to reach their original business case goals.1 Panorama Consulting puts the average cost overrun at 189%, with separate analysis of manufacturing environments (where supply chain planning complexity is highest) recording failure rates as high as 73% and cost overruns reaching 215%.2 These are not edge cases. They are the norm.
Yet only 30% of ERP projects are completed on time and within budget.2 For organisations investing hundreds of thousands, or millions, in digital planning capability, that is a sobering reality. The question is why, and more importantly, what can be done about it.
The Problem Isn't the Technology
When implementations fail, the instinct is to look at the software. Wrong configuration. Poor data migration. Inadequate integration. These things matter, but they are rarely the root cause. Research consistently points elsewhere: 48% of companies report that managing organisational change is their single biggest ERP challenge. A further 39% cite insufficient user training and support. And 53% identify misalignment between IT and business goals as a key driver of failure.3
The pattern is clear. Implementations do not fail because the technology does not work. They fail because the people, processes, and planning behaviours around the technology were never properly prepared.
"Technology does not resist change. People do. Digital planning only delivers value when people adopt it, and adoption is built before go-live, not after."
What Right-First-Time Actually Means
Right-first-time planning transformation is not about getting the go-live right. It is about ensuring the organisation arrives at go-live already capable: already aligned, already trained, already bought in, with planning behaviours embedded rather than bolted on.
This means the work of change enablement, capability building, and process redesign must begin at the very start of the programme, in discovery and design, not deployment and hypercare. It means planners understand not just how to use a new system, but why decisions are made differently within it. It means leadership is aligned on expected behaviours and equipped to reinforce them. And it means the right metrics are in place from day one so improvement is measurable, not assumed.
The organisations that achieve this, where new planning processes genuinely stick, share one characteristic: they treated the human and the technical workstreams as inseparable, not sequential.
Where Most Programmes Go Wrong
The most common failure mode is not dramatic. It is quietly assumed that the change management piece will take care of itself once the system is live. Training is compressed. Stakeholder engagement is treated as communication rather than genuine involvement. The planning team is expected to adapt on the fly.
The consequences are predictable. Workarounds emerge. Spreadsheets persist alongside the new system. Planners revert to familiar behaviours under pressure. The technology works as designed; it simply isn't used as designed.
This is how organisations end up in the alarming statistic that only 33% of companies report being satisfied with their ERP system, despite the significant investment made to get there.4
The Grange Approach: Planning Expertise Meets Change Enablement
At Grange, we work from a foundational conviction: digital planning only delivers value when people adopt it. That sounds obvious. In practice, it requires a fundamentally different approach to how transformation programmes are designed and delivered.
We blend deep supply chain planning expertise with human-centred change enablement, ensuring new systems, processes, and planning behaviours actually stick. This is not about adding a change management workstream to an otherwise technical programme. It is about designing the entire transformation so that adoption is built in from the start.
In practice, this means our planning specialists work alongside your teams during design. Not just to configure the system correctly, but to shape the planning processes, decision rights, and behaviours that the system needs to support. It means capability building that goes beyond system training to develop genuine planning competence. And it means change support that is grounded in the realities of supply chain planning, not generic change frameworks.
The result: faster, right-first-time digital planning transformations that deliver real, measurable improvements in supply chain performance, rather than expensive technology underused by teams that were never truly prepared.
What Good Looks Like
An organisation that gets this right arrives at go-live with planners who are confident, not anxious. Leaders who reinforce new behaviours rather than quietly tolerating the old ones. Planning cycles that work because the people running them understand the logic of the system and believe in it.
The KPIs that matter - forecast accuracy, inventory performance, service levels - begin to improve. Not because a new system was switched on, but because planning capabilities genuinely changed.
This is what right-first-time means. It is not about a perfect technical deployment. It is about transformations that stick.
