Rusted Nails in a Project
After 20+ years delivering enterprise programs (PMP), I’ve learned one thing the hard way:
Every project has “rusted nails.”
Project members whom you can’t replace—but who quietly slow things down, create friction, and turn small issues into major roadblocks.
So you either manage them early… or pay for it later.
Recently, I came across a powerful idea: using NPS (Net Promoter Score) to measure stakeholder engagement—not just customer satisfaction.
Think about it:
👉 Who are your promoters driving momentum?
👉 Who are your passives sitting on the fence?
👉 And most importantly—who are your detractors before they derail your project?
Because by the time a “rusted nail” becomes visible… it’s already costing you time, trust, and outcomes.
Subject Matter Experts (SMEs) may turn into detractors in a project due to a combination of fear, lack of engagement, and structural pressures, often transforming from valuable contributors into obstacles, a process sometimes called “SME creep”. Detractors typically arise when SMEs feel their expertise is undervalued, the project threatens their established workflows, or they have not bought into the project’s necessity.
Here are the primary reasons why SMEs become detractors in a project:
1. Cultural and Personal Resistance to Change
- Attachment to Legacy Systems: SMEs often have worked in their area for years and built strong opinions, causing them to resist new processes or software, especially if they see them as inferior to “how we’ve always done it”.
- Fear of the Unknown/Exposure: Change can spark anxiety that they will be judged for past inefficiencies, or they fear losing their authority and specialized status.
- Inherent Change Resistance: Some individuals are naturally resistant to change, needing high levels of involvement to overcome their inherent skepticism.
2. Lack of Engagement and Misaligned Goals
- Never Bought Into the Project: If an SME does not believe the project is a worthwhile use of their time, they may “quit” on it mentally, leading to disengagement.
- “Fake” or Unqualified SME: Sometimes, a “fake” SME is assigned—someone who is available, not truly an expert, or someone whose expertise is outdated (e.g., knows the old system but not the current, or thinks they know the work but have not done it recently).
- Unclear Role and Ownership: SMEs may become difficult if they do not know what their role is or if they feel they are being ignored by leadership who make decisions without their input.
3. Resource Constraints and Overload
- Too Busy/Overloaded: SMEs are often high-performers with heavy day-to-day workloads. If a project is added without removing other responsibilities, they may become frustrated and underperform on the project.
- Disruptive Changes: Projects can be seen as “corporate nonsense” or unnecessary bureaucracy that adds red tape, rather than a competitive advantage.
4. Psychological Factors and Trust Issues
- Feeling Unvalued/Appreciated: A lack of recognition for their expertise can lead to disengagement.
- Fear of Being Blamed: They may worry that they will have to live with the negative consequences of a poorly designed project after the project team leaves.
Summary of Detractor Behaviors
According to industry reports, a “flapping” or disengaged SME might display behaviors such as:
- Negativity and frequent complaints.
- Minimal attendance at meetings or not reviewing documents.
- Providing “surface-level” input without doing deep work.
- Undermining team efforts or creating conflict.
How to Mitigate SME Detractors
- Validate the Expert: Ensure the SME is a “current” expert and not just someone with historical knowledge.
- Involve Them Early: Engage them early to gain buy-in.
- Clearly Define Roles: Define what their role is and what ownership they have.
- Explain the “Why”: Connect the project to business metrics and explain the reasoning behind decisions
