David Maister wrote the book most professional-service firms still quietly run on. For a marketing or creative agency, the useful parts are leverage, utilisation, and the difference between doing the work and building a firm that can do the work.
Why it belongs on an agency shelf
Small studios often confuse busy delivery with a business. Maister is blunt about the economics underneath that feeling: who does the work, how junior and senior time mix, and why “we’re fully booked” can still be a weak firm.
Read it as a map of professional-service operations, not as a command to become a consultancy clone. The questions transfer cleanly to a five-person creative agency.
What to use
Use the book to name utilisation honestly, to stop pricing as if every hour were equally valuable, and to see hiring as a leverage decision rather than a panic response to a full pipeline.
Then put those ideas into a system the team will actually keep. The independent agency operating system is the practical counterpart on this site.
What to skip
Skip any urge to import large-firm hierarchy. Independent agencies need clear ownership, not extra management layers. Density is a feature of the book; you do not need to finish it before you document one handoff.
