A classic on leading expert teams. Balance sales, delivery and culture with numbers that keep the firm strong.

It made me respect the economics of services. It’s dry but deeply useful.
It explains how to run a consultancy or service firm without burning out.
For leaders, partners, and managers in professional service firms (e.g., consulting, law, accounting) who want to understand the unique challenges and best practices for managing talent, clients, and profitability.
David H. Maister’s Managing the Professional Service Firm is a comprehensive guide to addressing the unique challenges of managing organisations whose primary asset is intellectual capital. Drawing from his experience consulting across diverse industries, Maister provides insights into balancing client service, employee satisfaction, and financial performance. The book is structured around practical frameworks and actionable advice, addressing the lifecycle, structure, and dynamics of professional service firms (PSFs).
Maister identifies three interdependent goals for PSFs:
Balancing these goals requires careful management of leverage (the ratio of juniors, mid-level staff, and seniors) to match the demands of client work and internal career development.
Maister categorises PSF projects into three types:
Each project type dictates a different organisational structure and staff composition. For example, brains projects are less leveraged, requiring a high proportion of senior involvement, while procedure projects allow for greater use of junior staff.
Maister outlines the stages of a professional’s career—apprenticeship, mastery, and partnership. Career development within PSFs hinges on mentorship and the promotion of top talent. Firms must balance growth with retention to ensure a sustainable flow of opportunities for juniors while maintaining profitability.
Maister stresses the importance of building long-term client relationships through exceptional service and consistent delivery. Key tactics include:
Employee development is crucial for PSFs, as their value lies in intellectual resources. Maister advocates:
Maister warns against unchecked growth, which can dilute profitability and strain resources. He argues that sustainable growth stems from:
Effective governance in PSFs depends on aligning decision-making structures with organisational goals. Maister emphasises a collegial culture, where leadership inspires rather than dictates, and collaboration drives success.
Maister concludes that the unique dynamics of PSFs require tailored management practices. Success lies in balancing the demands of clients, staff, and financial performance while fostering a culture of collaboration and continuous improvement.
Managing the Professional Service Firm is a vital resource for leaders and managers seeking to navigate the complexities of professional service organisations effectively.

Most B2B marketers are either Random Ricks (trying everything) or Specialist Steves (obsessed with one channel). Generalists run tactics without strategy. Specialists hit channel ceilings. But there's a better way.

Tries everything at once. Posts on LinkedIn, runs ads, tweaks the website, chases referrals. Nothing compounds because nothing's consistent. Growth feels chaotic.

Obsessed with one tactic. 'We just need better ads' or 'SEO will fix everything.' Ignores the rest of the system. One strong engine can't carry a broken machine.
