There’s a fine line between planning just enough to move forward and planning so much that you never move at all. I’ve been on both sides of that line. One time, simple diagrams and steady iteration led me to a real launch. Another time, endless overthinking buried the project before it even began. I originally wrote more about these experiences on my blog at DevsMonkey
When Diagrams Help
Before starting to code, I once decided to sketch a handful of simple diagrams. Nothing fancy, just quick flowcharts and rough sequences to visualize what needed to exist first.
That effort created clarity. It:
Highlighted what was essential for the first version
Revealed potential pitfalls early
Made it easier to explain the idea and collect feedback
Because I had a loose map, the building process felt smooth. I didn’t waste time second guessing every decision. And when early feedback came in, I wasn’t trapped by rigid documentation, I could pivot and adjust quickly.
The diagrams gave me direction without locking me in. The result wasn’t flawless, but it was real. And that’s what mattered.
When Planning Blocks Progress
On another occasion, I did the opposite. I obsessed over every detail long before writing a single meaningful line of code. Pages of documents, countless diagrams, even imaginary infrastructure capable of handling millions of users. And yet, there wasn’t a single real person waiting for it.
Every “what if” became another week of planning. Every added feature delayed the start even further. The more complete the plan became, the heavier it felt, until the entire project collapsed under the weight of its own expectations.
That product never launched. It didn’t even reach prototype stage. All that remained was plans and no lessons from real users.
The Main Lesson
Planning is useful only if it helps you move forward.
- Light diagrams = clarity, direction, flexibility
- Heavy overplanning = paralysis, pressure, stagnation
The key is balance. Enough planning to know where to start, but not so much that you never take the first step. The best insights come from feedback, not from another week inside a document.
How to Plan Without Overplanning
- Sketch Quickly – Keep diagrams and notes rough. If you’re polishing them for days, you’ve gone too far.
Focus on Core Value – Define the one feature that gives the product its reason to exist.
Ship Something Small – Get a prototype or demo into someone’s hands. Real reactions are worth more than imagined scenarios.
Update, Don’t Rewrite – Use feedback to tweak your initial diagrams, not to redesign everything.
Accept Imperfection – Your first version will not be perfect. What matters is starting the cycle of iteration.
Planning can be your best ally or your biggest obstacle. Diagrams should be guides, not cages. They exist to point you toward action, not to replace it.
I’ve seen what happens when you plan lightly and build steadily: progress, feedback, and learning. I’ve also seen what happens when you drown in details: nothing. Between those two outcomes, the choice is clear.
If you’re stuck in endless plans, stop. Sketch just enough to see the road ahead, and start building. Even the roughest version in the real world is worth more than the most polished idea on paper.
