Decisive - Book Review

Updated: Nov 28


"Decisive: How to Make Better Decisions" represents the third installment in a series penned by the Heath brothers, Chip and Dan. These brothers, with an academic background, have consistently demonstrated their proficiency in creating exceptionally practical books that pertain to our everyday lives, all while pushing the boundaries of innovation. Published in 2014, this book predominantly explores the realm of decision-making biases. However, its principal emphasis extends beyond these biases, delving into effective decision-making strategies.

The book offers practical advice organized according to the various stages of the decision-making process:


Making the Right Decisions
  1. Start: Decision Alternatives

  2. Data Analysis: Evaluating Assumptions

  3. A Moment Before the Decision: Applying the Right Considerations

  4. After the Decision: What If We Made a Mistake…

  5. About the Process


If my enthusiasm hasn't already shone through in the warm words at the beginning, I enthusiastically encourage all readers to buy this book. It offers valuable insights for anyone engaged in decision-making, whether in an organizational context or in their personal lives.

I've already acquired and read it myself.


Start: Decision Alternatives

The Challenge:

Most people tend to contemplate only one option when it comes to decision-making. At the same time, some venture into comparing two choices, and a minority take the time to assess three or more alternatives. Restricting oneself to one or just two alternatives reduces the likelihood of arriving at a well-informed decision.


Recommendations:

Exploring Alternatives: Generate options by utilizing the following methods:

  • Reflect upon the opportunities lost due to the decision – consider what could be achieved with the resources, time, or money instead of pursuing the current course of action.

  • Envision a scenario where the existing alternatives are unavailable and, based on this, create additional choices.

  • Combine elements from existing alternatives to craft fresh selections.

  • Seek guidance from external experts or individuals who have previously solved similar problems.

  • Investigate within the organization or at home for solutions that have been discovered but have yet to be widely shared.

  • Create a list of thought-provoking questions that encourage the generation of new alternatives.

  • Employ analogies, whether close or distant, to inspire the development of novel choices.


Weighing the Significance of Alternatives:

Parallel Thinking – Simultaneously Addressing Multiple Alternatives:

  • Simultaneously, considering multiple alternatives contributes to a more precise definition of the specific needs or problems.

  • It diminishes personal ego, fostering a more receptive attitude toward genuine criticism of each alternative.

  • Cautions:

    • Refrain from an excessive proliferation of alternatives, which can lead to confusion and indecision. Ideally, aim for 2-3 alternatives.

    • Honesty is vital; avoid formulating illogical alternatives to conform to personal preferences.

  • Widespread stakeholder disagreement can indicate substantial alternatives that merit further discussion and evaluation.


Data Analysis: Evaluating Assumptions

The Challenge:

Our decision-making often relies heavily on the information we possess, even if it needs to be more manageable, complete, and representative. Furthermore, when seeking additional information to assess our assumptions, we tend to gravitate towards data reinforcing our existing beliefs while dismissing contradictory or unsupportive information. Trusting general statistics regarding our circumstances is difficult, as we often perceive ourselves as unique cases.


Recommendations:

Consider the Opposite:

  • Cultivate inner resistance as a tool to encourage openness to objective evaluation.

  • Actively seek information that challenges and weakens your assumptions.

  • Try to entertain opposing assumptions and thoroughly assess the feasibility of these contrary propositions.

  • Experiment in a direction opposite to your initial assumption and explore the resulting implications.


Rely on External Sources:

  • Investigate the experiences of other organizations and consult external statistics to gain a broader perspective.

  • Seek guidance from experts and engage them in discussions not only about the final decision but also about the underlying considerations and assumptions. Caution: Experts excel in recounting the past but may need help to predict the future.

  • In addition to examining broad statistics, gather individualized data to gain a more comprehensive understanding of the situation.


Conduct Limited Experiments to Confirm or Disprove Assumptions:

  • Carry out small-scale or partial experiments to validate the validity of your assumptions, providing insight into potential future outcomes.

  • This approach is especially relevant when the decision entails substantial commitments and implications.


A Moment Before the Decision: Applying the Right Considerations

The Challenge:

Our decision-making is often swayed by intense emotions, leading us to make choices that may not be in our best interest in the long run. We tend to favor the familiar.


Recommendations:

Distancing from Immediate Emotions:

  • Create mental space, either in terms of time or a change in your physical environment, before finalizing a decision.

  • Challenge yourself to consider the long-term consequences of your emotions instead of fixating solely on the immediate moment.

  • Try to empathize with another person's perspective and attempt to decide their point of view.


Identify Core Criteria and Evaluate Against Assumptions: It's More Complex Than It Appears...


After the Decision: What If We Made a Mistake...

The Challenge:

Acknowledging that the narrative doesn't conclude with the decision itself, there lies a future that we must address.


Recommendations:

Anticipating Future Implications:

  • Assess potential consequences, spanning from the best to the worst outcomes. While attaining pinpoint precision is rare, making a well-informed decision within this spectrum is more common.

  • Employ a pre-mortem approach to scrutinize the repercussions. This strategy involves learning lessons in advance by considering what could go wrong or right and the reasons behind it.

  • Prepare for the unknown by maintaining precautionary measures.

  • Evaluate potential emerging problems and risks and establish strategies to address them.


Recognizing Warning Signs: Instituting Signposts, a versatile approach with several benefits:

  • Allowing room for mid-course adjustments if the decision appears to be veering off course.

  • Enhancing risk tolerance by confining risks to specific aspects such as time and financial resources.

  • Possible signposts include setting timeframes, milestones, or deadlines for periodic reassessment.


About the Process

Recommendations for the Decision-Making Process:

  • Prioritize Negotiation: In situations where disagreements arise among involved parties, persist in negotiations until an alternative is reached that all parties can endorse. This method often results in more favorable decisions.

  • Emphasize Organizational Justice: The process of organizational justice profoundly impacts how individuals perceive the decision and our ability to manage the subsequent changes necessary for its implementation.

  • Proactively Address Concerns: When there's a concern that individuals affected by the decision might object, it's preferable to invest in extending the decision-making process and obtaining their consent or nurturing a sense of fairness in the process. This proactive approach is more effective than resistance during the implementation phase.

  • Value Consistency: Embrace a consistent decision-making process, even if it appears monotonous or ambiguous. The results validate the effort.
