This article aims to provide a practical and objective framework for making better decisions in both personal and professional contexts—particularly in areas such as recruitment, performance evaluation, and talent management—by outlining a clear, step-by-step method that minimizes bias and enhances consistency in judgment.

Key Takeaways:

• Structuring the Decision-Making Process

• Defining Mandatory and Preference Criteria

• Weighting Preference Criteria

• Making Decisions with Insight and Analysis

• Irreversibility of Decisions

Decision-making is a frequent part of our lives—not only professionally, but also personally. Often, without realizing it, the process can leave us mentally fatigued and uncertain. Yet, it becomes surprisingly manageable once we apply the right methods. In this context, I am not referring to decisions governed by laws, regulations, or standards. Rather, I focus on choices that fall outside formal frameworks—some of which can significantly impact our lives, while others may simply influence our day-to-day mood. Consider, for instance, selecting the right school for your child, deciding on the location and type of home when buying a house, or choosing the ideal destination for a long-awaited overseas vacation. These are all critical decision points.

In professional life, decision-making is constant—during hiring, promotions, talent identification, performance evaluations, and countless other HR decision-making processes. Suppose you run a law firm specializing in a specific field and plan to recruit legal trainees. You receive far more applications than available positions. How do you decide whom to hire? Or say you're launching a high-potential talent program—who will be included, and why? What criteria will you use to evaluate and provide feedback on employee performance? These scenarios are just a few of many.

Importantly, these professional decisions can significantly affect others. You may be shaping someone’s career. Therefore, such decisions shouldn’t rely on instinct alone—they require sound analysis.The term decision analysis is apt here, as it captures the idea of assessing multiple dimensions to guide your choices. While each of these dimensions matters, the extent to which they matter can vary. Making decisions individually may feel easier; however, in collective decision-making, each participant may have different priorities—and assign different levels of importance to them.

Step-by-Step Decision-Making Framework:

Step 1: Define the Decision Clearly

Start by writing a decision statement that clearly expresses what needs to be decided. It should be straightforward and free of assumptions or preferences.
Examples:
• 'We will hire three new lawyers, and we need to decide which applicants we will select.'
• 'I want to change my car, and I need to decide what type of car to buy.'
While the content of the decision may vary, the need for a clear decision statement remains essential.

Step 2: Identify Your Non-Negotiables

Determine your must-have requirements—ideally no more than two. These are essential conditions that every viable option must meet.
Returning to the legal recruitment example, mandatory criteria should reflect non-negotiable factors. For instance:
• If advanced proficiency in a foreign language is required, this is a suitable must-have—it’s measurable and objective.
• If your team operates exclusively from the office, then the requirement for in-office work qualifies as a valid non-negotiable.
Mandatory criteria must always be objective.

Step 3: Define Preference Criteria

Next, determine your preference criteria—qualities you’d like to see in an ideal option, even if they are not essential.
In collective decision-making, agreeing on which preferences matter is usually not too difficult. However, agreeing on how much each one matters can be more challenging.
When determining preference criteria, note the prominent preferences of each individual in the decision-making group. This is crucial for collective decision-making and for tracking performance after recruitment. Although it is not mandatory for preference criteria to be numerical, they must be subject to questioning and evaluation during job interviews.
Aim to limit preference criteria to no more than four—five at most. All participants should be heard, and the preferences should reflect a shared understanding of what matters most at this stage.

I would like to explain this by providing examples of preference criteria. These are given solely for illustrative purposes in order to clearly convey the method.

• Holding a Master's Degree in a Specific Legal Field

• Proficiency in More Than One Foreign Language

• Participation in the Firm’s Long-Term Practical Programs for Law Students

• Involvement in Extracurricular Activities During University

• Success Orientation

Step 4: Assign Weight to Preferences

By now, you should have:
• A clear decision statement,
• Agreed-upon mandatory requirements,
• A filtered list of viable options, and
• A set of preference criteria for evaluation.
Now comes a crucial step: assigning weights to the preference criteria. This determines their relative importance in the final decision.
At this point, you need to determine the impact level of each preference criterion. Rating all the preference criteria equally may create the risk of similar results. Therefore, it would be meaningful to assign higher weights to criteria that are not mandatory but could significantly influence the decision.

Let's assign weights to the five preference criteria we have defined above, again for illustrative purposes.

Preference CriteriaWeight
Participation in the Firm’s Long-Term Practical Programs for Law Students30%
Involvement in Extracurricular Activities During University25%
Holding a Master's Degree in a Specific Legal Field20%
Success Orientation15%
Proficiency in More Than One Foreign Language10%

Step 5: Last Point - Making the Decision

Let’s recall what we said in our decision sentence. 'We will hire three new lawyers, and we need to decide which applicants we will select.'
• You received 20 applications, and within this number, five candidates meet the mandatory criteria. The other 15 candidates were eliminated due to not meeting the mandatory criteria. As you can see, do not set the mandatory criteria in a way that leaves you without options.
• Now, you want to hire three candidates from these five, and you will do so based on the preference criteria and weights you have previously determined.
• For each candidate, rate them on a scale of 1 to 10 for each criterion, considering their resume and your evaluation during the interview. 10 represents the highest preference score.
• Create an Excel spreadsheet with all candidates and criteria. Rate each candidate on a scale of 1 to 10 for each criterion. Then, multiply each score by the weight percentage of the criterion in the decision. Calculate the total score for each candidate. The top 3 highest scores are your selected candidates. No turn back. 

Conclusion

In conclusion, making informed and objective decisions is essential in both personal and professional contexts. By following a structured decision-making process—starting from clearly defining the decision to carefully evaluating and weighting criteria—you can minimize bias and enhance the consistency of your judgment. Whether you're making hiring decisions, evaluating performance, or navigating critical life choices, applying these methods will help ensure that your decisions are well-grounded and fair. Ultimately, decision-making is a skill that improves with practice, and by utilizing these strategies, you can make more effective, deliberate, and impactful choices.
