Specification Snowball
We need something to replace a simple pager = simple just needs some old Nokias and sms.
Then everybody involved will add their own requirement because otherwise how do they justify being involved.
So as well as text messages it will have to be able to send 4d video and feature smello-vision
Security is important so it will have to be designed from scratch to the highest levels of military grade magic and so use no COTS parts
It will need to interoperate with 6 other "not yet totally designed" emergency services comms systems.
It will have to be built by approved suppliers in several deprived areas by companies whose brother in law is a cabinet minister
It will be delivered late, if at all, won't work and the handset will have a battery life of 10mins and will need a fork lift to lift.
