Before anyone designs a screen or writes a line of code, someone has to answer a deceptively simple question: what does the business actually need this project to achieve? A Business Requirements Specification (BRS) is the document that captures exactly that — the business goals, needs, and outcomes a project must deliver, in language the…
In 1999, NASA lost the $125 million Mars Climate Orbiter because two teams wrote the same requirement in two different units — pound-force on one side, newtons on the other. Nobody fumbled the math. The math was fine. The requirement was ambiguous, and an ambiguous requirement is a landmine with a long fuse: it sits quietly…
Here is a statistic that should reorganise a few budgets: somewhere around 80–90% of workplace accidents trace back not to broken machines but to how the work was designed for the humans doing it. Human factors work optimisation is the practice of designing tasks, tools, and environments around human capabilities — to cut error and…
Right now, if you’re a system engineer scrolling through your LinkedIn feed, there’s a good chance you’ve seen the headline: “AI Engineer” is the fastest-growing job title on the platform, outpacing every other tech role in the past three years. Maybe you’ve also noticed that 78% of organizations used AI in 2024 according to Stanford’s…
For decades, eliciting requirements meant interviews, workshops, and a lot of manually wrangled documents. Then large language models arrived and quietly changed what one analyst can get done in an afternoon. In the AI era, eliciting, writing, and analysing requirements means pairing proven engineering discipline with AI tools that can draft, check, and stress-test requirements…
Not all project uncertainties are created equal — so why do so many teams dump them into one undifferentiated pile? RAID and RAIDOC are register frameworks for tracking the things that can sink a project: Risks, Assumptions, Issues, and Dependencies — with RAIDOC adding Opportunities and Constraints. Used well, they turn vague anxiety into a…
Every requirement tells the system to do something. A safety requirement is different: it tells the system what must never happen, no matter what. A safety requirement is one whose failure could lead to harm — injury, death, or serious damage — which is exactly why it is written, verified, and traced to a higher…
There is a brutal rule of thumb in engineering: a requirements mistake caught at the desk costs a dollar to fix; the same mistake caught at testing costs a hundred; caught after the system ships, it can cost ten thousand or a life. Capturing and defining requirements is the work of getting those statements right…
A CONOPS tells you how a system will be used. But “the operator needs to respond quickly” is a vision, not something you can build or test. The real work sits in between. Defining operational requirements is the process of translating the operational concept (CONOPS) into specific, verifiable requirements an engineer can actually deliver against….
You can build a system that passes every technical test and still get it completely wrong — because it does its job beautifully under conditions nobody will ever actually face. A Concept of Operations (CONOPS) is the document that stops that from happening. It describes, in plain language and from the user’s point of view,…
