1. Delay decisions until you have enough information
Many developers think they need to decide everything at the start of a project.- Which database should we use?
- How will we handle authentication?
- What framework should we build on?
2. Focus on abstractions, not implementations
When writing software, always code against abstractions, not specific implementations.Here’s a simple example:- Bad approach: You decide upfront to use MySQL, and you write all your queries directly in MySQL syntax.
- Better approach: You use an abstraction layer like an ORM (Object-Relational Mapper), so you can switch databases later if needed.
3. Keep your system decoupled
Decoupled systems mean parts of your software don’t depend too much on each other.Here’s why this is important:- If you decide too early on one technology, it can force your whole system to follow that path.
- When you avoid tight connections, your code stays flexible and easier to change.
4. Avoid the trap of “premature decisions”
Imagine you decide on a technology before fully understanding the problem. Then, months later, you realize you need something different.Now you have two choices:- Throw away months of work and start over.
- Try to force your system to work with the wrong technology.
5. Unknown problems will appear – stay ready
No matter how much you plan, you will always face surprises.- Maybe the product requirements change.
- Maybe a new security issue forces you to switch technology.
- Maybe your team realizes a different approach is way better.
Final thought: Always ask “What’s the abstraction I really need?”
Next time you start a project, ask yourself:- Am I making decisions too soon?
- Can I delay this choice until I have more information?
- What’s the best abstraction for this problem?
