For many years, in our work with innovation portfolios, we’ve seen organizations pour immense time, money, and energy into Project Portfolio Management (PPM) tools – yet PMO and innovation leaders report the same recurring frustrations: low adoption, stale data, endless manual workarounds, and a widening gap between how teams actually deliver work and how PPM tools expect work to happen.

We’ve even heard from companies that have spent two years trying to make Microsoft’s PPM stack work for them before ultimately abandoning the effort. Not because their PMO was immature. Not because their teams resisted change. But because the tool was simply not built for the way their organization actually delivers work.

While vendors promise structure, oversight, and strategic clarity, the reality inside many PMOs looks very different. At the heart of the failure lies a rarely discussed but deeply systemic issue:

PPM tools are far too tightly linked to the execution layer.

And that single flaw sets off a chain reaction of pain for PMOs, teams, and executives alike.

1. When the PPM Layer Mirrors the Execution Layer Too Closely

Most legacy PPM systems were born in a waterfall world. Their data models assume predictable phases, homogeneous project types, and one “proper” way of doing projects.

But modern organizations don’t work like that. In a single portfolio, you are likely to see:

• Classic waterfall projects (often PRINCE2‑style)
• Agile delivery (Scrum, Kanban, SAFe, “generic agile”)
• Hybrid models that keep evolving

When the PPM tool is tightly coupled to any one of these ways of working, it becomes brittle and exclusionary. Instead of mirroring business reality, it enforces methodology dogma.

The result is a portfolio layer that doesn’t really represent the portfolio.

2. A Forced Waterfall Mindset in a Hybrid World

When the PPM tool’s underlying logic mirrors waterfall, everything – from project setup to reporting – assumes linear, gated, phase-based progression. This leads to PMOs experiencing:

• Difficulty onboarding agile projects
• Inability to map iterative delivery into rigid structures
• Teams forced to “waterfallize” their work to satisfy reporting needs
• Frustration from product owners, scrum masters, and dev teams
• Reports that misrepresent what is actually happening

No wonder teams resist entering data – the system simply doesn’t reflect their world.

3. Lack of Flexibility: Multiple Ways of Working, One Way of Reporting

A modern PMO must accommodate coexisting, parallel, and evolving delivery models. But PPM tools often demand:

• One standard structure
• One lifecycle
• One definition of “project”
• One way to forecast, plan, measure, and report

This rigidity forces the PMO to spend enormous energy translating, coaching, and manually reconciling mismatches between how work is done and how the tool wants it done. And every manual workaround widens the trust gap between PMO and delivery teams.

Usability Issues That Guarantee Low Adoption

Layered on top of all this is the user experience problem. Most PPM tools suffer from:

• Too many mandatory fields
• Confusing navigation
• Rigid workflows
• Steep learning curves
• Burdensome data entry
• Inconsistent UX across modules

This leads to the most predictable outcome in the PMO universe:

Low adoption → stale data → loss of trust → manual workarounds.

And once the PMO resorts to spreadsheets “to make the tool work,” the entire business case for the PPM system collapses.

5. When Systems Don’t Get Updated, the PMO Becomes the Workaround Factory

Because teams avoid the tool, portfolio reviews rely on offline summaries, and status reports are made in PowerPoint.

Instead of enabling strategic decision-making, the PMO becomes an administrative buffering layer between teams and executives. PPM tools should eliminate this burden – not amplify it.

So What’s the Real Takeaway?

Most PPM tools fail because they operate on an outdated assumption:

That portfolio management is just an aggregated view of project execution.

But portfolio management is a translation layer, not an extraction layer. It requires judgment, pattern recognition, scenario analysis, prioritization, and strategic sense-making – not raw task-level data pulled from MS Project or Jira.

Until PPM tools decouple themselves from the execution layer and allow PMOs to define flexible, human-centered models of work, PMOs will continue to struggle with:

• Low adoption
• Inaccurate reporting
• Manual workarounds
• Misalignment between strategy and delivery

The future of portfolio management is not ever‑tighter technical integration with every execution tool.

 It is:

• Looser coupling between portfolio and execution  
• Smarter abstraction of data into decision‑ready signals  
• Flexible ways of working and reporting that can embrace new delivery models instead of fighting them

At Nosco, we see this every day when innovation initiatives move from ideas to funded projects. The PMO’s real value is to connect strategy and delivery across many ways of working – not to force everyone into one template.
