How I Support Business Efforts with Software
Ask four questions to help your team align their efforts with business expectations.
What is the purpose of this project? This is to avoid building unnecessary things.
What goal do we want to achieve? It should be linked to something valuable to our stakeholders.
Who will be affected by it? It's essential to involve these people in decision-making about the project.
Finally, how can those people help us achieve the goal? The group of people affected by the changes or project can either help or hinder the project.

Domain-Driven Design Model Human Interactions
Software design should reflect automated human interactions with a system.
As we witness the digital revolution unfolding, it's becoming clear that the economy is less about money and more about people. The digital economy is defined by combining people and software, determining how people interact within a system.
It's important to note that software is created by people, for people.
Developers use a technique called Domain-Driven Design to tackle system complexity. By doing so, they are changing how people interact with each other in the digital economy.
Domain-driven design helps to define a vocabulary that domain experts support.
Communication with domain experts helps to uncover the motivations behind the requirements. This terminology allows developers to understand the organization from a software perspective. Designing software involves finding why you're building it in the first place.
By focusing on communication, developers can build software designed for people, not machines.
The digital economy is about people and software working together.

The Role of TDD in System Design
As developers, every line of code we write is a crucial decision. That's where TDD comes in handy. It helps us confirm these decisions by providing feedback.
We make design decisions, and TDD enables us to get feedback.
Testing ensures, but it doesn't mean it affirms. Testing principles offer a cost-effective and flexible way to extend an existing system. Testable systems provide adaptability for future changes. Yet, having a testable system does not mean the design is robust. It depends on the code creator's TDD practice knowledge.
The primary benefit of TDD is not adding more tests for the sake of it. The focus is on breaking down the problem into manageable pieces that can be analyzed.
