Sorry Stuart, lost track of this one. Our system is Taskmaster by TBS. (Google Taskmaster PDA). My training was 1 day. It takes a while to get to know all the ins and outs though. Like Tomas says, you need to manage your time well, and I think if you're not great with paperwork then you won't be great with this either. I find the best way is to enter each job on the PDA as you complete it, otherwise you spend too much time at the end of the day trying to sort it out. You still need to use a paper diary as a back up, and we also use a paper time sheet. I tend to fill in these first. Our system forces you to at least close down the jobs for the site you are on before going to another. We also have to close jobs at the end of the day. You can close them as awaiting parts, order number etc, and then retrieve them later by a phone call to the office. Management use the figures that the system generates to show customers how efficiently we are performing, so it is important we keep to the rules. There are safeguards built into the system, however. If you "forget" about a job the system doesn't, and emails your Service Manager
