Connascence is a powerful concept for understanding the hidden dependencies between software components. Unlike generic discussions of coupling, it breaks interdependence down into specific, measurable types — such as name, timing, or meaning. This helps developers reason about change impact more effectively and communicate design concerns with precision.

Styles of Support

Helping Attitudes refer to the various roles helpers can adopt when assisting others in problem-solving, ranging from listening passively to actively diagnosing and prescribing solutions. Flexibility in shifting between these roles ensures relevant and adaptive support. The helper’s ability to move between attitudes such as Rubber Duck, Process Consultant, Crafter, and Doctor, based on the client’s needs, is essential for maintaining a balanced and effective helping relationship. This pattern highlights the importance of understanding power dynamics and re-engaging in a reflective, non-directive manner when necessary.

Thinking in Systems

stijn@sddevelopment.be (Stijn Dejongh) — Wed, 31 Jul 2024 00:00:00 +0000

Explore Systems Thinking, a technique that emphasizes viewing situations as interconnected systems rather than isolated parts, helping manage complexity by focusing on interactions and relationships. Learn how this approach is applied across various fields to develop effective, sustainable solutions for complex problems.

Cognitive Biases

Discover the concept of cognitive biases, systematic errors in thinking that influence how we perceive the world, make decisions, and interact with others. This page explores the origins, key components, and practical applications of cognitive biases, providing insights into social, memory, emotional, and decision-making biases. Learn how understanding these biases can improve judgement and foster better personal and professional relationships.

Chain of Accountability

The Chain of Accountability is a structured hierarchy ensuring clear roles and responsibilities in project implementation. It comprises phases from defining goals to executing strategies, tactics, and follow-up. Originating from the military chain of command, this model is adapted for civilian use to provide clear accountability in various contexts. Key components include defining goals, strategies, tactics, execution, results, rollout, and follow-up.

Heartfelt Dialogues

Understanding the dynamics of Emotional Conversations helps us navigate the complexities of communication, acknowledging how emotions influence our interactions and often lead to misunderstandings. By recognizing the stages of message processing and the factors that influence emotional responses, individuals can better navigate conversations, reduce misunderstandings, and foster more effective interactions.

The Testing Pyramid

stijn@sddevelopment.be (Stijn Dejongh) — Sun, 01 Oct 2023 00:00:00 +0000

The Testing Pyramid categorizes various test types, ranging from isolated tests that provide fast, highly focused feedback to integrated tests that simulate real-world scenarios but demand more setup effort. Developers must strike a balance between feedback speed and realism when choosing the right tests for their context.

The pyramid offers a versatile framework, with different test types serving specific purposes, from function/method tests for core logic validation to end-to-end tests for comprehensive system validation. Additionally, user-interface tests, exploratory tests, recovery tests, and user feedback play crucial roles in uncovering unexpected behaviours and gathering valuable insights, though they come with their unique challenges. By Understanding these testing categories, software teams can craft effective testing strategies that enhance software quality.

Memento Mori

The concept “Memento Mori” emphasizes the importance of remembering our mortality to live a meaningful and purposeful life. It encourages us to focus on what truly matters, ensuring our actions align with our values and legacy. By reflecting on death, we can prioritize our time, relationships, and productivity more effectively. The concept is compared with other philosophies and practices that also address the transient nature of life, though with different approaches and outcomes.
