In this episode, I dive into the management mantra that "what is measured is managed" and explain why this simple assertion often leads to a complex trap. We discuss why the act of measuring team productivity is never neutral—it's an intervention that immediately changes behavior, often resulting in unintended consequences like gaming the metrics. We'll explore how to collaborate with your team to find measurements that truly drive desired behaviors.Understand why the phrase "what is measured is managed" means that measuring something triggers management of that thing, in varying degrees.Learn why the act of measuring something is an intervention, especially when done with the intent of turning it into a target (e.g., increasing PRs or decreasing bugs), and how this action is shown to change behaviors around the thing being measured.Discover how measurement can lead to unintended consequences, such as when tracking velocity via story points causes team members to inflate or deflate their estimates, making the

I want to dive into the concept of Deliberate Practice, which sets the greatest apart in fields ranging from sports to writing to engineering. I’ll explain why it’s much more than just repetition or experience, and why applying it to your career can lead to rapid improvement. Most importantly, I will provide concrete ways you can apply deliberate practice to level up your engineering and leadership skills, especially in areas that are traditionally difficult to practice, such as communication and strategic decision-making.Differentiate Practice from Deliberate Practice: Understand that while repetition is part of practice, deliberate practice specifically involves engaging in a very narrow set of activities with the intentional goal of improvement, requiring very quick feedback for continuous incorporation.Identify Opportunities for Rapid Improvement: Learn why deliberate practice is much more effective at achieving rapid improvement than simply engaging in repetition.Apply DP to Leadership Skills: Discover h

This episode explores the concept of Locus of Control and why developing a more internal locus of control is beneficial for your career and life. You'll learn the difference between internal and external perspectives, why one is more useful than the other, and practical exercises to shift your mindset to believe you have more influence over the outcomes you care about.Understand Locus of Control: Discover what psychologists mean by locus of control—whether you believe outcomes are determined by your own actions (internal) or by external forces like luck and chance (external).Adopt a More Useful Mindset: Learn why an internal locus of control, while not a perfect reflection of reality, is a more useful and effective mindset for your career, as it prevents you from missing opportunities to influence outcomes.Recognise Your Influence: Find encouragement in the idea that you almost certainly have more influence and control over situations in your life and career than you currently believe.Shift Your Perspective w

In this episode we'll discuss why "Résumé Driven Development" is a powerful mental model for building a thriving career. Instead of seeing your résumé as just a job-hunting tool, you'll learn to use it as a guide for setting measurable, impactful goals that benefit you, your manager, and your company.Focus on Impact, Not Just Tasks: Discover why a great résumé is built on proof of impact, not just a list of completed projects. The best way to improve your career is to focus on achieving measurable goals that demonstrate real value.Have the Goals Conversation: Learn how to initiate a critical conversation with your manager to define measurable goals for your role. If your manager can only provide project deadlines, take the initiative to propose your own impact-oriented goals.Connect Goals to Business Value: Understand the importance of linking your work to business metrics. While there's a risk that a project might not meet its business goals, you can also measure impact through clever technical solutions or

In this episode, we introduce a simple yet powerful mental model from the world of sports: forced vs. unforced errors. By understanding this concept, you can shift your focus from things outside your control to the simple, foundational behaviours that truly define a successful career.Understand the Difference: Learn the distinction between forced errors—mistakes caused by chance, situation, or randomness that are hard to prevent—and unforced errors, which are avoidable blunders resulting from a lack of attention or care.Focus on What You Control: Discover why the most successful engineers prioritise reducing their unforced errors. While most people worry about hard-to-predict "forced errors," top performers concentrate on the fundamentals they can directly influence.Identify Your Unforced Errors: Recognise common unforced errors in your career, such as not testing your work, being late for meetings, erratic communication, or posting unprofessional content online. These simple mistakes can significantly impact

In this episode, we introduce two fundamental thought experiments to help you uncover your true priorities and core values. By exploring scenarios of scarcity and abundance, you'll learn to align your daily actions with what truly matters, leading to a more satisfied career and life.Uncover Your Priorities: Engage in a "5% exercise" where you imagine only being able to complete a tiny fraction of your to-do list. This thought experiment leverages a scarcity mindset to reveal your genuine priorities, helping you distinguish between what you perceive as important and what truly is.Discover Your Values: Participate in an "abundance exercise" by imagining all your obligations are met and you have complete autonomy. What you choose to do next in this state reflects your core values and helps you move beyond aspirational or culturally normative answers.Go Deeper: Learn to challenge superficial answers when identifying your values, pushing beyond the obvious to find unique and potentially surprising insights that ge

This episode explains what is arguably the best career advice you'll hear this week: the one skill that signifies seniority in software engineers is the ability to synthesise and optimise for multiple factors at once. Instead of focusing on a single factor, such as performance or maintainability, senior engineers identify and weigh the various trade-offs involved in any decision.Discover the key skill that distinguishes a senior engineer: It's the ability to synthesise multiple, competing factors—like performance, maintainability, cost, and time to market—rather than focusing on just one.Learn why single-factor thinking can hold you back: Junior engineers often optimise for what they know best or what is easiest to measure, which can harm the overall solution, the team, and their professional reputation.Understand how to demonstrate seniority in interviews and at work: You can show your maturity and wisdom by identifying the crucial trade-offs for any given problem, asking what factors need to be balanced, an

This episode focuses on the critical importance of having a backup plan, not just for technical redundancies but especially for situations involving human error, which are highly prevalent in one's career. The core argument hinges on understanding risk and reward curves, highlighting the disproportionate impact of failures compared to incremental successes.Understanding Risk and Reward Curves:Successes are often incremental. Delivering a project on time typically leads to opportunities for more projects, good performance reviews, and modest pay increases (e.g., 5-7%). These are positive, but linear or slightly bumpy gains.Failures, especially uncaught ones, have a much longer negative tail. The potential for loss from a significant mistake or a disastrous project significantly outweighs the potential for gain from a success.A bad performance review, for example, can affect future reviews, decrease promotion likelihood, and follow you for a much longer period than a good one.Uncaught failures can place individ

Todays episode delves into understanding and leveraging second and third-order consequences – the ripple effects that occur after an initial action – and introduces forcing functions, which are an inverted way of thinking about these consequences, designed to drive desired outcomes by first determining "what must be true" for them to occur. The episode also connects these concepts to the importance of effective goal setting, explaining how well-defined goals provide clarity, focus, and a strategic framework for decision-making and career advancement.Grasp Second and Third-Order Consequences: Learn to identify the downstream effects of initial actions. For instance, setting a target for test coverage (first action) might lead to people adding tests that don't genuinely test anything but merely inflate the metric (second-order consequence), potentially resulting in disillusionment with testing or continued incidents despite high coverage (third-order consequence). Conversely, giving someone ownership or autonom

This episode delves into the philosophical concept of hyperobjects – problems so vast and complex they lack clear boundaries and cannot be "solved" once and for all. It explores why attempting to permanently fix issues like technical debt, user experience, or performance management is often ineffective. Instead, it offers a new perspective: how to interact with and manage these intractable problems by focusing on specific outcomes and accepting their ongoing nature.Understand hyperobjects as problems that extend beyond clear boundaries and time, such as technical debt or performance management, which cannot be truly "solved".Discover why a "one-time fix" approach is an anti-pattern for hyperobjects, as their dynamic nature means solutions must also be continuous.Learn to shift your mindset from "solving" to "interacting" with these large, persistent problems, focusing on managing their effects rather than trying to contain them.Explore the importance of focusing on specific, achievable outcomes and taking "sn

This episode delves into a powerful model for encouraging behaviour change, applicable to both managing others and self-improvement, by focusing on three critical factors: Trigger, Incentive, and Ability. It challenges common, ineffective management approaches and provides insights into fostering new habits and desired actions by making the 'right' thing the 'easy' thing.Uncover why naive management approaches, such as mandating rules or blaming individuals, are ineffective at solving underlying behavioural problems or creating new, lasting habits.Learn about the Trigger, Incentive, and Ability model, a set of principles that can be applied to encourage specific actions in others or to facilitate self-betterment and incorporate new behaviours into your own life.Understand that Incentives are the critical factor in deciding what actions to pursue, driven by the question, "what's in it for me?". It's crucial for incentives to be clear and understood; an unclear incentive is effectively no incentive at all. Bene

This episode delves into the crucial role of well-positioned goals in a developer's career. It asserts that goals provide clarity, perspective, and purpose, particularly focusing on clarity as a primary benefit. The discussion challenges common struggles with goal setting, including the often-overlooked importance of relevance (the 'R' in SMART goals), suggesting that an irrelevant goal, no matter how specific or measurable, is ultimately ineffective. The core message highlights that the purpose of a goal is to serve as a clarifying and prioritising tool, enabling you to make decisions about what to do and focus your efforts, rather than simply doing work that is handed to you. You will learn to start small and focus on desired outcomes or what you want to be true, accepting that a goal only needs to be "directionally correct" rather than perfect. The episode also provides a practical heuristic: to set goals by considering how your boss will evaluate your performance in the future. It emphasises the importanc

Today we explore Cognitive Load Theory. This concept can profoundly influence how you structure your workday, manage teams, and approach learning in your career. The episode highlights that much of professional work, particularly in knowledge-based roles like software engineering, is fundamentally about learning. You will discover that there is an optimal amount of information processing for effective learning, and both overloading and underloading your cognitive capacity can be detrimental. A key insight is that cognitive load does not discriminate; all external factors, whether work-related or personal (e.g., tiredness, a messy desk), consume your finite cognitive capacity, leaving less "headroom" for optimal performance. Furthermore, cognitive load is not static but varies daily, impacted by an individual's diverse life experiences. The episode also delves into how skill development effectively lowers the cognitive load required for specific tasks, allowing individuals to achieve more with less mental effo

This episode focuses again on the fundamental principle that your systems are perfectly designed for the outcomes you are experiencing, regardless of whether those systems were intentionally or accidentally created.Here are the key takeaways from the episode:Uncover how your systems, whether intentionally or accidentally designed, are perfectly configured for the outcomes you experience. The implication of design means choices have been made in setting up a system, but your intent is less important than the actual outcomes produced.Learn why your intent is less important than the actual outcomes when evaluating your systems. If your intent was the sole factor, everyone would achieve their desired results. Instead, systems should be judged by the outcomes they generate.Discover the concept of "accidental design," where unseen factors influence system behaviour. This can be inspired by Goodhart's law, where a measure becomes a target and changes behaviour, or by environmental factors, such as how your workspace

This episode discusses why perfection is a dangerous and fragile goal, explaining how striving for 100% leads to unsustainable outlier states. It highlights how setting perfection as a bar can cause commitments to break and plans to fail due to a lack of slack, and offers strategies like building redundancy and planning with slack to achieve goals more effectively without relying on perfection.Uncover why perfection is a dangerous and fragile goal, as it often requires exorbitant, unsustainable effort and creates outlier states that are unlikely to be maintained, referencing the "Wedies effect" where things tend to regress to the mean.Learn how planning for 100% utilisation or setting perfection as a commitment can lead to fragility, causing plans to fail when unexpected changes occur or leading to giving up altogether once a "perfect" streak is broken.Discover practical strategies to avoid fragile perfectionism, such as planning with slack to accommodate change and building redundancy into your systems and p

This episode introduces the potentially controversial principle that your system is perfectly designed for its current outcomes, urging listeners to embrace greater responsibility for systemic issues. It explores how to redefine system boundaries to holistically integrate all influencing factors, like talent and organisational processes, ensuring that interventions are effective and targeted.Uncover the principle that your system is perfectly designed for the results you are getting, prompting a re-evaluation of what constitutes a "good" system when outcomes are undesirable.Learn why arbitrary system boundaries often lead to critical factors, such as talent, being excluded, and how to consider a system's full scope regardless of traditional lines of responsibility.Discover how incorporating talent and other seemingly external factors into your system design can lead to more efficient and effective solutions, rather than simply patching symptoms.Explore the distinction between judging decisions by their outcom

This episode explores the fundamental mindset of building your vocabulary, extending beyond literal words to conceptual understanding and mental models, and how Large Language Models (LLMs) can be a powerful tool for expanding and refining this crucial skill for career growth, clarity, and navigating disruptions.Uncover why building your vocabulary is a fundamental skill that can help you navigate career transitions, disruptions (such as those caused by AI), and changes in roles.Understand that "vocabulary" goes beyond literal words to include mental models, understanding your own self, specific diagrams (like causal loop diagrams or C4 diagrams), and programming paradigms or design patterns. This conceptual vocabulary provides access to nuanced and powerful ways of thinking.Learn how LLMs can be incredibly useful for refining and expanding your conceptual vocabulary, allowing you to explore new subjects, understand systems, and identify leverage points. They can help you understand the connotations, origins,

This episode delves into the use of substitute questions—simpler queries we use to answer more complex ones—and the crucial concept of cohesion between these substitutes and our true objectives. You'll learn how to leverage counterfactual thinking to scrutinize your assumptions and enhance the effectiveness of your decisions. Discover two powerful counterfactual techniques: asking "what else could be true?" to reveal alternative explanations, and employing thought experiments to, for example, precisely define your desires and career aspirations. The discussion offers practical applications, from refining hiring processes by identifying high-cohesion interview criteria to avoiding confirmation bias in debugging. By adopting counterfactual thinking, you can significantly improve your analytical skills, make more informed choices, and build robust strategies.Uncover how cognitively taxing questions lead us to use substitute questions as heuristics, and why understanding the cohesion between these is vital for ac

This episode explores why maintenance tasks, despite their fundamental importance, are often neglected or deprioritised in our daily lives and professional work. It delves into the psychological biases that make consistent maintenance challenging, such as hyperbolic discounting, where immediate gratification is valued over future gains, and the construal level theory, which highlights how psychological distance makes preventative work less impactful. The concept of the "maintenance paradox" is introduced, explaining that when maintenance is done well, its benefits go unnoticed, diminishing the sense of reward. The episode encourages listeners to adopt a maintenance mindset, making these tasks a standard habit rather than relying on typical prioritisation structures, as they are crucial for enhancing the quality of overall experiences and preventing future, more urgent problems.People tend to discount future gains or devalue them relative to immediate gratification, a concept known as hyperbolic discounting. T

This episode introduces a profound yet simple principle: knowing your baselines. This concept is crucial for effectively detecting and measuring change in your life and career.Uncover the fundamental idea that to recognise when something has changed, you must first understand what things were like before the change occurred. Often, people haven't been measuring their lives, making it challenging to spot shifts because their baselines are unknown.Learn to identify your personal baselines across various aspects of your life. This includes understanding typical daily habits, such as whether you tend to skip lunch, or how many hours you usually work (e.g., 6, 8, or 10 hours). While general data might suggest optimal working hours (e.g., 35-45 hours for most benefit, rarely more than 55 hours), your personal baseline is unique, and the goal is to empower you to make conscious decisions about your habits.Explore other crucial areas for baseline measurement, including simple health metrics like your typical body wei
