Simple Rules: How to Thrive in a Complex World by Donald Sull and Kathleen M. Eisenhardt is a compelling guide designed to help individuals and organizations navigate through complexity by using simple, actionable rules. The book distills strategic execution into a manageable and efficient process, emphasizing the importance of simplicity in overcoming complex challenges. Below is a structured summary of the book, encompassing its main points, practical advice, and concrete examples.

Introduction

Simplicity is pivotal in driving effective decision-making and actions in a world overwhelmed by complexity. Donald Sull and Kathleen Eisenhardt argue that complex problems do not always require complex solutions; rather, they can often be addressed through a set of simple, yet potent, rules.

1. The Value of Simple Rules

Major Point:

Simple rules are essential because they provide a balance between rigidity and chaos. They enable quick decisions while maintaining flexibility to adapt to new information and situations.

Specific Action:

Identify and articulate a small number of simple rules that align with your key objectives. For instance, if your goal is to improve customer service, your rules might include always answering customer inquiries within 24 hours and following up on customer feedback within a week.

Example:

In the book, the example of the 19th-century Prussian army is given. They developed deceptively simple tactical rules: “March separated, strike united,” which allowed them to quickly adapt to battle conditions and ultimately led to numerous military successes.

2. Types of Simple Rules

Major Point:

The authors identify three main types of simple rules: boundary rules, prioritizing rules, and stopping rules.

Specific Action:
  1. Boundary Rules: Define clear boundaries to guide behaviors or choices.
  2. Action: Create boundaries for your project’s scope. If you’re managing a marketing campaign, specific rules about target audiences or mediums used can prevent scope creep.

  3. Prioritizing Rules: Help in making decisions about what to prioritize.

  4. Action: Establish prioritizing criteria for your tasks. If preparing for an exam, prioritize study topics based on their weight in the test.

  5. Stopping Rules: Indicate when to stop a certain activity or approach.

  6. Action: Define exit criteria for a project phase. If developing a product, a stopping rule could be ceasing additional features when 90% of customer feedback is positive.
Example:

The trading firm RBC Asset Management uses simple rules for stock investments: they only invest in companies with a competitive advantage, a management team with a proven track record, and a stock price below intrinsic value. These rules have led to consistently strong investment performance.

3. How Simple Rules Work

Major Point:

Simple rules work by offering a middle ground between no structure and overly bureaucratic processes. They harness the benefits of bounded rationality and leverage collective wisdom.

Specific Action:

Observe experienced practitioners and the strategies they employ. Extract the simple rules that drive their success, and tailor these rules to your context.

Example:

IDEO, an international design and consulting firm, fosters creativity with simple brainstorming rules such as “defer judgment” and “build on the ideas of others.” These rules create a conducive environment for innovation without suffocating structure.

4. Crafting Simple Rules

Major Point:

Creating effective simple rules involves identifying a bottleneck or critical issue, drafting candidate rules, and refining them through iterations and feedback.

Specific Action:

Focus on identifying the most pressing bottleneck in your workflow or process. Draft a few simple rules aimed at addressing this specific area, test them in practice, and adjust based on results.

Example:

Fast food giant McDonald’s identified speed of service as a critical issue. They simplified operations with highly specific rules like “make French fries every seven minutes,” which ensured both speed and consistency, becoming a cornerstone of their success.

5. Applying Simple Rules in Various Contexts

Major Point:

Simple rules can be applied across diverse domains – from personal life to business to societal issues – making them universally relevant.

Specific Action:

Examine different areas of your life (personal habits, work processes, social interactions) and apply simple, guiding principles tailored to each context.

Example:

In personal finance, the authors cite the “50/30/20” rule: allocate 50% of income to needs, 30% to wants, and 20% to savings and debt repayment. This simple structure effectively manages complex financial decisions.

6. Maintaining and Evolving Simple Rules

Major Point:

Simple rules must evolve over time to remain effective, given changing circumstances and new information.

Specific Action:

Regularly review and update your rules to ensure their relevance. Evaluate their effectiveness and modify them based on feedback and observed outcomes.

Example:

The example of the Silicon Valley tech company NVIDIA illustrates this principle. They update their product development rules based on rapidly changing technology trends and market feedback, ensuring they remain competitive.

Conclusion

Simple rules are powerful tools for managing complexity across various domains. They provide clarity, guide actions, and enable adaptability. By identifying key priorities, setting clear boundaries, and knowing when to stop, individuals and organizations can navigate through intricate challenges with efficiency and effectiveness.

Summary of Actions from Book:

  1. Identify and Articulate Simple Rules: Establish a small set of rules aligned with key objectives.
  2. Types of Simple Rules:
  3. Boundary Rules: Define clear behavioral boundaries.
  4. Prioritizing Rules: Set criteria for prioritizing tasks.
  5. Stopping Rules: Establish criteria for ceasing activities.
  6. Learn from Experienced Practitioners: Observe and extract effective rules from successful examples.
  7. Craft and Refine Rules: Identify bottlenecks, draft rules, and refine them through feedback.
  8. Apply Across Domains: Tailor simple rules to various parts of your life or business.
  9. Maintain and Evolve: Regularly review and update rules to adapt to changing conditions.

Through these strategies and examples, “Simple Rules” demonstrates that simplicity, when well-implemented, can universally thrive amidst complexity. The book’s emphasis on practicality and adaptability makes it an indispensable guide for strategic execution in an intricate world.
