I’ve long claimed that capturing the rationale for any business requirement/solution decision/whatever is possibly more important than capturing the actual requirement. Well, ok – as important as, then 🙂 Stumbled upon a good story today to back that up:
The problem is that if you can’t even explain why your own company does it this way, I am quite unconvinced that it could not be done better. For example, when more than a decade ago I worked with a large British newspaper company, I asked why their papers were so big. Their answer was “all quality newspapers are big; customers would not want it any other way.” A few years later, a rival company – the Independent – halved the size of its newspaper, and saw a surge in circulation. Subsequently, many competitors followed, to similar effect. Yes, customers did want it. Later, I found out that the practice of large newspapers had begun in London, in 1712, because the English government started taxing newspapers by the number of pages they printed — the publishers responded by printing their stories on so-called broadsheets to minimize the number of sheets required. This tax law was abolished in 1855 but newspapers just continued printing on the impractically large sheets of paper.
Many practices and habits are like that; they once started for perfectly good reasons but then companies just continued doing it that way, even when circumstances changed. Take time to think it through, and ask yourself: Do I really understand why we (still) do it this way? If you can’t answer this question, I am pretty sure it can be done better.
This isn’t just important to prevent bad decisions now, but also to be able to prevent bad decisions later when circumstances change and business evolves. If you can’t remember why you did something in the first place, you don’t have a clue whether it is going to be a problem to do something else 🙂
