I am just on the train on the way home from London and I have just seen yet another person mortified by the fact they forgot to lock the automatic sliding doors…
I have seen this a few times over the years like many fellow travellers, but I have never really given it that much thought until now. It struck me how wrong a whole raft of people have got this design. I can’t for the life of me think of a reason why an automatic toilet door wouldn’t automatically lock after pressing the close button on the inside of the cubicle. You have to press a second lock button, which a lot of people forget to do as they subconsciously assume the same!
There is a serious point here about getting requirements right. How much would it cost to fix this now? How much would it have cost during planning? I don’t know, but a multiple of 100x is often used in the business analyst fraternity.
Usually, functional stuff like this is picked up early, but it is much more common for the non-functional stuff to be forgotten about until the end. Examples include:-
- How are we going to provide support?
- How much will it cost to operate?
- How secure is it?
- Does it comply with information governance law?
In extreme cases the only solution is to call in the bulldozers and start again!
