The Flow Economics Maturity Model: Where Does Your Portfolio Actually Sit?
There is no shortage of maturity frameworks in project and portfolio management. P3M3. OPM3. CMMI. Gartner’s PPM maturity model. They have all been applied across organisations of every size and sector, and most large enterprises have used at least one of them to benchmark where they sit.
They are useful. They have helped many organisations move from chaotic, unstructured delivery toward consistent, repeatable performance. The discipline they have brought to the profession is real.
But for all their usefulness, most maturity frameworks tend to peak at structured governance, repeatability, alignment and continuous improvement. They rarely describe the next layer explicitly: managing the portfolio by optimising the economic value flowing through constrained resources.
That gap is not an oversight. It reflects the state of the field when those frameworks were developed. The concepts required to define a higher level - constraint economics, value per constrained resource hour, dynamic portfolio optimisation - did not exist in an operationalised form. They do now.
The Flow Economics Maturity Model - the FEMM - picks up where existing frameworks leave off. Six levels, from local activity optimisation to constraint value optimisation. It is not a judgement. It is a map.
The six levels
Each level represents a different organising principle - a different answer to the question "what is this organisation optimising for in how it runs its portfolio?"
Level 1: Activity Focus
The organising principle is keep everyone busy. Performance is measured by utilisation. Full schedules are healthy, unallocated time is waste. Prioritisation is informal, driven by who makes the strongest case or the seniority of the person asking. Projects are approved because there is budget, not because there is capacity. Chronic overload is normal. Firefighting is the default. The organisation mistakes busyness for productivity.
Level 2: Project Focus
The goal has matured to delivering projects successfully. Project managers are empowered. Methodologies are in place. Governance frameworks exist at the project level. But the portfolio is still a collection of independent efforts. Projects compete for the same resources without visibility of each other. Each project manager believes their work is the highest priority. Portfolio performance is measured by adding up individual project results - which assumes the projects do not interfere with each other, an assumption that is almost always wrong.
Level 3: Structured Portfolio Layer
Governance frameworks now exist at portfolio level. Dashboards and heatmaps provide visibility. A PMO or portfolio office coordinates activity. This is genuine progress. The organisation can finally see its portfolio in a way it could not before. But prioritisation is still human-led and politically influenced. The data is better. The decisions are still driven by seniority, relationships, and whoever argues most convincingly in the room.
Most organisations reading this will recognise themselves somewhere between Level 2 and Level 3. That is not failure. It is the reality of where the profession currently sits. The question is what comes next.
Level 4: System-Aware Resource Management
The organisation has begun to understand that the portfolio is a system and that systems have constraints. The language of Theory of Constraints and Critical Chain is entering the conversation. Bottlenecks, buffers, and constraint management are understood intellectually. Constraint identification is possible. But the thinking has not yet been fully operationalised. The organisation knows the language. It has not yet changed its behaviour.
Level 5: Flow-Based Portfolio Optimisation
This is where Flow Economics thinking begins to operate in practice. Theory of Constraints is fully operational. The constraint drives priorities. Dynamic reprioritisation is system-guided rather than human-led. The organisation no longer asks "who is working on what?" - it asks "what is the system telling us should be worked on next?" The shift from intuition-led prioritisation to flow-based sequencing is complete.
Level 6: Constraint Value Optimisation
Genuinely new ground. Few, if any, mainstream maturity models describe this explicitly. Traditional governance frameworks rarely reach it. Projects are prioritised not just by flow but by economic value yield. The central question is no longer "what should be worked on next to maintain flow?" It is "what should be worked on next to maximise the economic value produced by each hour of constrained resource time?" Portfolio mix is optimised dynamically. Investment decisions are made with full visibility of drag cost, DIPP, and value per constrained resource hour. Flow and economics work together as a single integrated decision system.
Why moving up is harder than it sounds
Each transition in the FEMM requires not just different tools or different processes. It requires different thinking, and often different leadership courage.
Moving from Level 2 to Level 3 means accepting that project prioritisation cannot be done in isolation. Approving a new project is not just a decision about that project. It is a decision about every project already in the system.
Moving from Level 3 to Level 4 means accepting that human-led prioritisation at scale is structurally insufficient. There comes a point where the complexity of the problem exceeds what any human can track, regardless of experience or effort. That is uncomfortable to admit. It feels like saying experienced judgement is less valuable than an algorithm. It is not. It is saying experienced judgement is most valuable when informed by data no human could generate alone.
Moving from Level 4 to Level 5 means accepting that the system should guide decisions, not just inform them. This is where most organisations stall. It feels like loss of control. What it actually means is that leaders are freed from the decisions the system can make better - and can focus their judgement on the decisions that genuinely require it.
Moving to Level 6 means accepting that the economic value of delivery timing is as important as the fact of delivery itself. A project delivered three months early is not a scheduling success. It is a financial event. And the decisions shaping when value arrives are investment decisions, and should be made with investment-level rigour.
None of these transitions are primarily technical. They are cultural. That is the real work of moving up the FEMM.
What you can do with this
The most useful thing the FEMM offers is honesty. It gives leadership teams a way to look at where their portfolio actually sits, without judgement, without consulting jargon, and without the implication that anything below the top level is failing.
The point is not to shame Level 2 or Level 3 organisations. It is to make the current operating logic visible, so the next move can be chosen deliberately.
Most organisations are succeeding at the wrong thing. The FEMM names what they are succeeding at, and shows what becomes possible at the next level. The decision about whether to move is theirs. The map exists so the decision can be made deliberately.
Take the next step
If you want a structured view of where your portfolio currently sits across the six levels of the FEMM, take the Flow Economics Maturity Assessment. It takes about ten minutes and gives you a clear read on your current level, the constraints holding you there, and the practical moves required to progress.
