Requirements aren’t paperwork – they’re engineering.
If you’ve ever wondered why writing them feels painful, slow, or like it stopping “real work” from happening, this is the article for you.
Here’s the blunt truth: Getting requirement right early is the different between a project that lands cleanly and one that burns time, money, and reputation later.
Have you ever been writing requirements and thought “I can’t be arsed for this – we know what we are building why are we writing all this down?”
Or have you heard your PM say something like “We just need it delivered so we can get paid“
You’re not alone and I get it.
This is what some people don’t understand: requirements aren’t paperwork! They’re the shared language between engineering intent and project reality. They’re the thing that stops your project from quietly setting itself on fire six months down the line.
Why Requirements Actually Matter
Requirements drive everything – design, cost, schedule, customer satisfaction, and ultimately whether the thing you’re building is legal, safe and sellable.
Miss requirements early?
You will pay for them later.
Miss major functional or legislative requirements? You get unhappy customers, blown budgets, and a reputation that follows you around like a bad smell.
Let’s make it real.
A Quick Example (That Happens More Often Than Anyone Admits)
You’re designing a vehicle. Tight timescales. Pressure from the business to hit payment milestones. Requirements are rushed. Corners get cut. A few “we’ll sort that later” items slip through.
One of those items? A key legislative requirement.
You don’t notice until Critical Design Review.
Suddenly the entire electrical architecture is non‑compliant — and illegal to sell.
Now you’re looking at:
- Redoing early design work
- Annoyed suppliers
- Annoyed bosses
- A furious customer
- A PM scrambling to find money that doesn’t exist
All because the team wasn’t given the breathing room to get the requirements right the first time.
And the worst part? It was avoidable.
The Bottom Line
Requirements are messy, complex, time‑consuming, and — let’s be honest — to everyone else it often looks like nothing is getting done.
But this is the work. And when requirements are rushed or skipped entirely, the damage shows up later in the project when it’s far more expensive, far more visible, and far harder to fix.
The way around this is simple: engage earlier with systems engineering and put real development time into the plan. And everyone needs to accept a hard truth — requirements are never, and I mean never, right the first time.
Requirement writing is iterative and recursive. It takes multiple passes to get them clear, testable, and aligned with reality. That’s not a failure. That’s the process.
Ultimately, if a business cares about making it work, then they already care about requirements – whether they realise it or not.
