suboptimal

I was doing a bit of mechanicing the other day. As with any practical job I do, the first x amount of time is spent searching for the tools and materials.

spanner

On this particular occasion though it was more like x times 5 time spent ratching around looking for stuff.

The job involved mainly 10mm bolts (approx 3/8″?). I had no bother finding a 10mm spanner, in fact I had a couple. But a socket would have been much better for this job. Pictured is an 11mm socket – I found 2 of them, but I could not find the 10mil. In fact I think I have (had) at least 2 of them too, although it looks like I need another.

I spent a fair bit of time wielding the spanner thinking how much easier it would be with the socket. Both when I took it to bits, and again when I rebuilt it.

I find software dev to be similar, whether to go with the known, known to be poor approach, or spend an unknown amount of time and effort searching for a better way.

How might you describe that?

If (time/effort poor way) > (time/effort best way + time/effort to find it) * (1/chance of finding it)) then best way else poor way.

Or

If (time/effort saved best way – time to find it) * chance of finding it > 0 then try the best way.

In my case I reckoned the time taken to find it (if possible) would be way more than the saving so I just did it with the spanner.

I guess there is also a ‘preference’ factor (prefer researching to working badly), and maybe a ‘pressure’ factor too?

Do you have the same though process? how would you describe yours?

cheers

    You need to factor in the sheer intellectual pleasure of discovery. I’m often tempted to offer clients a discount if I’ve learnt something exciting during a project, though I’m going to admit that I’ve never actually carried it through.

    I always keep my socket sets in their original cases. It’s tempting when you’ve finished a physical job just to chuck your tools randomly back in the shed and forget about them. You’ll buy yourself a couple of minutes in this way, and cost yourself hours in the future. I sound like someone’s dad, don’t I?

    I think I get what your saying, I got a bit lost in the maths :-)

    I tend to go:
    How long the way I know, if it’s ages then think about a better way?
    How long to learn the better way?
    Use once or use many?
    New way intresting/cross training?
    Pleasure of Intellectual Discovery? (PID)*

    I run this all though the Mclean super computer (very fast core processor) and then make my choice.

    P.S. You get your sockets from Halfords?!?!

    spod

    If you must know, its a replacement for the other 11mm I lost, although the original set was nowt special (draper).
    Don’t tell me you’re a snap-on snob?

    use once or many is a good point

    BTW I’m waiting for Nick to send me some of these:

    Dad indeed. I don’t just chuck them in randomly – I put them somewhere clever to improve efficiency on the next job. Which is much harder to recover from.

    lol!
    To be fair, my Dad was a engineer so i did have some decent kit growing up, I tend to get my spanners from the pound shop now!

  7. Rob Bruce Says:

    Aren’t pound shop spanners generally made out of cheese?

  8. ross Says:

    Yeah they are, but they cost a pound, lol!
    I only need them to tighten up my tabel legs!
