The Lean Manager: summary and review

A Novel of Lean Transformation

By Michael Ballé and Freddy Ballé. First published 2009.

The short answer

The Lean Manager is a 2009 business novel about Andrew Ward, a plant manager who must keep a failing plant open and, in the process, change how he manages. Guided by Phil Jenkinson, the mentor from the authors' earlier novel The Gold Mine, he stops handing out orders and answers and starts asking questions and developing people. The authors' claim is that companies change only as fast as their leaders do. It suits managers who already know the basic tools and want the human side. Beginners will struggle with the terminology.

Read it if

  • You run or support a plant and want to see what changing your own management habits feels like over a year.
  • You coach managers and want a shared story to discuss, chapter by chapter, in a book group.
  • You have already read a lean foundations book and know terms such as kanban and SMED.

Skip it if

  • You want the tools explained. The book uses them with little introduction, according to Jon Miller's review.
  • You need a ready routine for supervisors. A novel shows a mindset; it does not give forms or cadences.

When it pays off: Read it after your first round of tool-based improvements has started to fade. It addresses why results slip when managers keep managing the old way.

The core ideas, in plain language

  1. 1

    Companies change as their leaders change

    Ballé says in a 2018 Lean Enterprise Institute article that the story is about the company changing through its leaders, who learn from a sensei. It is not about tool deployment.

  2. 2

    Lean cannot be done to someone else

    In a 2009 exchange with Mark Graban, Ballé describes lean as a line management method and a problem-solving attitude, not something a consultant can do for you.

  3. 3

    Answers give way to questions

    Ward moves from telling people what to do to asking questions that help them find and address problems. The publisher puts this change at the center of the plot.

  4. 4

    Tools serve people development

    Kanban, SMED and kaizen appear throughout, as ways to expose problems and teach people. The publisher stresses becoming lean rather than doing lean.

  5. 5

    Learning from someone with authority over you

    Ballé notes that learning from a boss who teaches differs from picking a mentor you like. The CEO's coaching is a main thread, according to Miller's review.

  6. 6

    Both characters are the lean manager

    Ballé says Jenkinson and Ward both play that role, which is why the book is more about Ward's growth than Jenkinson's method.

How to use it on Monday morning

  1. 1

    Read two chapters with a small group

    Pick two or three supervisors and engineers, read the same two chapters, and have each person try one thing on the floor before you meet. Ballé's 2018 book club advice is to read, try, share results, then discuss.

  2. 2

    Replace one instruction with a question

    For one shift, when you would tell someone how to fix a problem, ask what they see and what they think causes it. Note which questions got useful answers.

  3. 3

    Spend 20 minutes at one problem with one team leader

    Go to a process where a problem keeps returning and have the team leader explain it at the spot. Offer no solution until the second visit.

  4. 4

    Name who teaches you

    The book assumes a mentor with authority. Write down who that is for you. If nobody, decide whether to ask your boss or find an outside coach.

What to be careful about

  • Long and dense

    Jon Miller's 2009 review calls it hard to recommend as required reading at about 450 pages. The publisher lists 471. He finds the middle strongest.

  • Jargon from the start

    Miller notes it uses kanban, SMED and kaizen without introduction, so it works better as a second or third lean book.

  • The opening can be read as lean is mean

    Reviewer Jaap van Ede objected that the CEO's early actions, including removing quality inspectors and threatening closure, might reinforce that view. Ballé replied that lean is tough but not mean.

  • A story is one case, not evidence

    A Reliable Plant reviewer says it should not become a literal roadmap for another company.

The Lean Manager compared with Creating a Lean Culture

The Lean Manager shows a year of changing a manager's behavior through one plant and one mentoring relationship. David Mann's book gives the routines: leader standard work, visual controls, accountability meetings. Pick the novel for the coaching relationship and mindset. Pick Mann when you need cadence and forms to build.
