Most organisations do not become messy all at once.
They grow into it. A few more people join. The work changes. More clients, funders, partners or board members need information. Decisions that used to happen quickly start taking longer. The same issues come up again because nobody is quite sure who owns them.
That does not mean the organisation is broken. It usually means the way the work runs needs a bit of attention.
Messy Middle helps you step back, find the parts causing the most friction, and fix the right thing first.
Ownership
Who decides, who follows through, and where responsibility is becoming unclear.
Operating rhythm
Which meetings help the work move, and which ones are covering for unclear decisions.
Processes and systems
Good teams do not always need more structure. Sometimes they need simpler structure.
