PLM projects fail for two kinds of reasons. The first is the software. A platform that is too complex sees low adoption. One that is too heavy takes years to deploy. One that is too rigid forces teams to adapt to the tool rather than the other way around.
The second is the deployment itself, and this is the one that gets underestimated. The challenges that surface during a rollout are rarely anticipated during planning, and sometimes the planning does not even happen before the rollout starts.
This article covers the second category: the PLM implementation challenges that derail projects regardless of which platform you chose. Knowing them in advance is what turns them from problems into planning items.
At Aletiq we have run deployments for manufacturers of every size, from three-person startups to multi-site groups with 20 sites and 3,000 users. What follows is what we see go wrong, what it costs, and how to avoid it. Deployment can be painless, but only if you prepare for it properly and choose a provider who guides you through the process.
📌 TL;DR
Some software used in manufacturing is single-purpose. It serves one team and affects one team's work. PLM is like an ERP: it’s cross-functional. It touches engineering, manufacturing, quality or even supply chain, and its impact shows up in budgets, non-conformities, time to market and competitive position.
Three consequences follow.
Each function needs to contribute its requirements, separate the must-haves from the nice-to-haves, and sign off on the final decision. Getting agreement from six functions is harder than getting it from one, and it takes longer. It also produces a decision people defend rather than tolerate, which is what adoption depends on, and adoption is what ROI depends on.
A CRM with imperfect data is still useful. A PLM with imperfect data is actively dangerous, because production builds from it. That raises the standard for migration from acceptable to correct.
Configuring a PLM means deciding how change requests are approved, who owns a part number, and what a released revision means. Those are organizational decisions wearing technical clothing, and they take longer than the configuration itself.
A successful PLM implementation doesn't run itself. On the manufacturer's side, a dedicated project manager is essential: someone who owns the project end to end, keeps it on track, and ensures the rollout stays aligned with the initial plan and deadlines.
This person is more than a coordinator. They become the internal champion of the tool: the go-to expert who understands the platform deeply and can support other teams when questions arise. That proximity to the tool accelerates adoption across the organization.
When this role is unclear or shared across multiple people, decisions slow down, timelines slip, and the implementation loses momentum. The impact is direct: the smoother the deployment, the faster teams reach full adoption, and the faster the company sees a return on its investment.
Executive buy-in directly shapes how the implementation unfolds and how the tool gets adopted across the organization.
When management pushes the decision to implement a PLM without involving operational teams, the software feels imposed rather than chosen. Resistance to change multiplies, and adoption suffers because the tool is rarely configured to reflect how people actually work.
The opposite is equally damaging. When management doesn't fully grasp the importance of the platform, they may limit resources, slow down key decisions, or set unrealistic expectations, all of which create friction at every stage of the project.
Beyond the management layer, cross-functional alignment matters just as much. When teams from engineering, quality or manufacturing are involved early, the platform gets shaped around the real needs of each function. That alignment doesn't just improve implementation, it carries over into day-to-day work. Shared processes, clearer handoffs, and fewer miscommunications translate directly into fewer errors and better time allocation across the board.
The most consistently underestimated challenge, and the one that delays the most projects.
Legacy systems accumulate years of inconsistent practice: duplicates, informal naming conventions, missing attributes, and dependencies that exist only in someone's head. In daily operations, teams learn to work around it, sometimes without even noticing. During migration, however, it all surfaces at once and directly impacts the success of the PLM project.
At Aletiq, roughly 90% of our clients arrive with data quality issues that need addressing before migration can proceed. That's not a criticism, it's simply the reality of companies that have grown organically over years and that didn’t have a central source of truth. Poor data quality is a common starting point, not a blocker. We work alongside our clients to clean and structure their data before migration, so the transition is as smooth as possible.
Who owns the part number? What system manages what data? If a field exists in both PLM and ERP, which one is the source of truth?
These questions have no default answer, and leaving them unanswered does not delay the project. It produces a system where data diverges silently and nobody is accountable for it. The cost appears later.
To get the most value from a PLM, it needs to exchange data with your ERP, CAD tools, and often MES and QMS systems. Each has a different data model, and mapping between them is almost always more work than initially planned.
There's also a foundational question that's easy to overlook: for each data type, you need to decide where the source of truth lives. Will you manage your BOM in the PLM and push it to the ERP, or the other way around? Settling this at kickoff saves significant rework later.
To make integration as painless as possible, look for a PLM with native connectors maintained by the vendor. This ensures data synchronization quality and removes the IT burden from your team.

The most common single cause of PLM disappointment. Introducing a PLM is a significant change for your teams, because it affects processes as well as data management, and most people resist change even when the current way is not working well.
As mentioned earlier, the decision to move to a PLM needs to be aligned across teams, so everyone knows why the change is happening, how it affects their daily work, and what they get out of it. More transparency means less resistance, and less resistance means better adoption.
At Aletiq, we believe training is the other half of adoption. The more people understand what the tool can do, the more they use it, which is why we run training sessions tailored to each team rather than one generic session for everyone, and why we schedule additional sessions whenever a team asks. A generalist session covers the basics. Getting a function to actually master the tool means training built around how that function works.
The goal of a PLM is to digitize and automate processes and bring full traceability to them. To do that, those processes have to be standardized, and this is where the problem usually sits: the same process runs differently from site to site, or varies depending on which team launches it.
Standardization does not mean every process runs identically. For multi-site organizations, you standardize the processes that span sites and let each site define its own local ones. For single-site organizations, standardizing mostly means bringing clarity and rigor to how things already run.
The challenge manufacturers create for themselves. Over-customization is occasionally justified, but for 85% of manufacturers it only creates cost.
We often see the instinct to configure the platform to match every existing process, including the inefficient ones, or to reproduce the old data model exactly. The result is a system that is expensive to maintain and difficult to upgrade, a deployment that takes two to three times longer, and development costs added on top of the deployment bill.
Most legacy processes are workarounds for limitations of the old system rather than genuine requirements, and reproducing them carries the limitation forward. Errors in identifying which functionality genuinely meets user requirements produce unnecessary development and a steady flow of change requests afterward.
Product data is intellectual property, and often subject to customer confidentiality or export control. Access rules have to reflect that.
The difficulty is calibration. Too open and you have a compliance exposure. Too restrictive and people cannot do their jobs, which sends them back to email attachments and undoes the governance you just built.
Knowing the list is less useful than knowing when each one arrives. A challenge anticipated at kickoff is a planning item. The same challenge discovered during migration is a delay.
Two patterns are worth noting.
Governance appears twice. It is decided during process mapping and it bites six months after go-live, when the decisions made early turn out to be wrong or were never really made. It is the only challenge on this list with a long delay between cause and symptom.
Data quality surfaces late but originates early. It exists before the project starts and is discovered during migration, typically at the worst possible moment. This is the strongest argument for auditing data during scoping rather than assuming it is fine.
PLM projects are rarely abandoned outright. They underdeliver instead, which is harder to see and harder to fix.
Budget overrun. The direct cost, and the most visible. Usually driven by data remediation discovered late, scope that was never properly defined during planning, over-customization, or project delays.
Partial adoption. Probably the most expensive outcome. It happens when teams keep using legacy systems because the new one does not meet their needs, when the change was not managed properly, or when the platform is simply too complex to use.
ROI that never materializes. The business case assumed faster change cycles and fewer errors. Neither happens if adoption is partial and processes are unchanged.
Organizational fatigue. The hardest to quantify and the most consequential. A failed PLM project makes the next digital initiative harder to fund and harder to staff.
Five practices address most of these challenges at once, which is more useful than one countermeasure per item.
Not before migration. Before scoping. Knowing the state of your data determines the timeline, the budget, and whether the first wave should be narrower than planned. This single practice addresses the challenge that delays the most projects.
For every data type that will exist in two systems, name the master and the accountable team. Write it down and make it visible. It takes a morning and it prevents the failure that surfaces in year two.
Use the implementation to eliminate workarounds rather than encode them. When a team insists their process is a genuine requirement, ask what would break if they adopted the standard. Sometimes the answer is real. Usually it is habit.
Deploy a narrow first wave and defer the rest to a second one that is actually scheduled. Academic work on PLM implementation describes deliberately postponing lower-priority functionality to a later wave specifically to compress the first deployment, with build work split into time-boxed sprints so users give feedback throughout rather than at the end.
At Aletiq, we always recommend that our customers opt for a progressive rollout and start with the most critical perimeter. Besides the valuable user feedback, the change will be smoother and it will give people time to get used to the tool.
A PLM delivers more when it is configured around how its users actually work. Involving them during configuration does three things at once: they understand how the tool works and what they gain from it, they become the people who drive adoption inside their own teams, and the system ends up doing what they actually need.

The challenges in this article apply to both deployment models. What changes is their weight.
The difference is scale. A cloud deployment averages 8 to 12 weeks, with no infrastructure to build, less to configure, and low IT involvement from your teams. An on-premise project runs from eight months to two years, and costs more for the same reason.
A longer, heavier project raises the stakes on three of the challenges in particular. Project management and ownership matters more, because a two-year project needs sustained control rather than occasional attention. Executive sponsorship matters more, because commitment to something long and expensive has to survive changes of priority. Over-customization is a more common trap, because on-premise platforms are known for how far they can be customized, and that capability comes with heavy IT costs and continuous involvement from your own teams.
None of these nine challenges is a surprise. They show up in almost every PLM project, in roughly the same order, for roughly the same reasons. Most of them are organizational rather than technical, and that is what makes them easy to underestimate. Choosing the right platform matters, and it is the first of the two categories we opened with. But the platform will not audit your data, decide who owns a part number, or agree which of your three sites has the right process. Those remain yours.
What a good provider brings is pattern recognition. After enough deployments they know which challenge arrives at which phase, so you schedule for it instead of reacting to it.

Data migration and data quality, user adoption, integration with existing systems, and process standardization are the four most common. Project management, executive sponsorship, data governance, over-customization, and access control account for the rest. The majority are organizational rather than technical.
Rarely because of the software. The recurring causes are data quality discovered too late, processes that were never standardized, governance decisions nobody made, and adoption that was assumed rather than managed. Most failures are partial: the system runs, but half the organization keeps its spreadsheets.
Very. At Aletiq, around 90% of clients arrive with data quality issues that need addressing before migration can proceed. Duplicates, inconsistent naming, and incomplete attributes accumulate over years, and they only become visible when a new system validates them.
Involve users during configuration rather than only during training. Teams who helped define how the system works defend it to their colleagues. Beyond that, make sure the old path is genuinely closed, because adoption fails most often when the shared drive is still available.
Yes, mainly because the project is lighter. A cloud deployment averages 8 to 12 weeks with no infrastructure to build and low IT involvement, against eight months to two years on-premise. The challenges themselves are the same in both cases. A longer project simply raises the stakes on project management, executive sponsorship, and over-customization.
For cloud-native platforms, 8 to 12 weeks is realistic for a first wave including data migration and integrations. Enterprise on-premise platforms typically run 8 to 24 months. The largest variable in either case is data quality, which is why auditing it before scoping matters.
