I would have said what
@Clinton said (except that I would not have used expressions like 'core resilience' and 'strategic path' and to be honest, I wouldn't know a core resilience if it came up and bit me on the nose - and as for a strategic path, you could serve me one of those on a silver platter with watercress round it and I wouldn't be any the wiser - but I digress!)
I think what
@Clinton is banging on about, is that you should offer people more than just fixing their phones. (That'll be all that bit about 'building width and depth'.)
The fact is, the cards are getting reshuffled and re-dealt every few months. What is today a specialist service, is tomorrow's domestic consumer activity. Change is everywhere and the rate of change is accelerating. These are for any business person, very exciting times - but not times for a specialist service that hopes that tomorrow will just go away and leave them alone.
Tomorrow has arrived in the form of one OAP with a screwdriver!
Tomorrow comes on very soft shoes and in different guises. Ten years ago, we bought a machine that does a very specific task for £9,400 plus VAT. Today, every function of that machine can be performed by any one of many free downloads.
Everywhere you look, today is being replaced by tomorrow. VHS was replaced by DVDs which were replaced by BluRay, which was replaced by downloads and streaming in HiDef which is rapidly being replaced by 4K. TV sets will be replaced by projectors and projectors will be replaced by intelligent walls.
Mono was replaced by stereo, stereo was replaced by 5.1 and 7.1 surround, surround is now being replaced by Atmos and a former intern that used to work here, is now working on the replacement for Atmos!
That's the trouble with tomorrow - just when you think you are all ready to welcome in the next day, someone tells you that they are working on the day after the day after that! Intel has teams working on chip designs that are (using today's production technology) actually physically impossible to build - but they know that in six-to-eight years time, it will be possible and they will have the designs ready to fly.
Right now, iPhones look like the last word in technology. I cannot think of a gadget more destined to be replaced. It is bulky, fragile, expensive and technically very limited. Fixing this doomed technology would be the last business I would want to get into!
