- At 10-20% of total organization size, oversight is not cheap. (see PMO Headcount Sizing). And it tends to grow. One CIO commented sagely "PMO's are a cancer; left unchecked they grow to choke the real work of the enterprise."
- In addition, oversight adds a 20-50% hidden tax on the work overseen. Teams are forced to add staff and time to address the inappropriate, rigid methods, unproductive review meetings, redundant reporting, and excessive documentation imposed in the name of oversight.
- Moreover, oversight frequently raises non-issues to emergency status, causing teams to expend time and resources chasing phantoms just to stay in good stead.
- Finally, excessive oversight checkpoints add wait states that cost real money. In one egregious example, a PM told me that 66% of his project budget was spent waiting for EA & PMO approvals.
- Contrary to popular belief, an outside, non-practitioner cannot spot risk by imposing method or by periodic inspection. Even a savvy practitioner will shy away from the responsibility of pronouncing project health, or finding project fault, by casual inspection. She knows that risk is best exposed and mitigated by, and while, doing the work.
- Delays imposed by oversight transfer the risk from the program to the mission. And in some cases, not having a mission solution is riskier than any risk generated in creating a solution. For example, one federal agency has spent so long reviewing a project that the mission capability is literally months away from functional failure.
- Oversight stifles innovation by its rigid adherence to "standards" - mindlessly sticking to the "way we know." Failure to keep pace with the knowledge gained by industry experience builds technical debt, a form of adding risk.
- Finally, oversight leads to information hiding. The dirty secret is that teams tell "oversight" what it wants to hear to make them go away. Oversight then reports inaccurate information to decision makers and dependents. It may take months or even years, but eventually the disconnect between perception and reality will become obvious. And by then, the damage is more extensive, harder to contain, and mitigation far more costly.
Superior risk reduction and efficiency can be achieved not by costly oversight, but by other means. I'll leave describing those other means for later.
