John can change and improve the way he works using different technologies such as,

PDA: A PDA can be used to easily take down information and data, it has a touch screen that can be signed by his clients, this reduces the amount of paperwork that he has to carry around, it also has the ability to connect to the internet, this could prove useful if John needs directions or needs information on something. PDAs are seen as obsolete now as smart phones are able to do just about everything they are able to do.

GPS: A GPS or Global Positioning System are able to locate where he is on the map and give him directions based on where he is and where he wants to go, this could be very helpful as it would mean he wouldn't need to carry around a map all the time. And a GPS is easier to follow than a map so there's less of a chance that he will get lost and end up being late. So a GPS is also able to improve his punctuality. It will most likely come with a built in calculator, further reducing the amount he has to carry.

Laptop: A laptop is useful for many things, it can be a way to easily give information and get directions, or it can be a good way to spend free time on, as you're able to connect anywhere as long as there is free wifi. He is also able to use software such as Excel to help him with managing clients, decreasing the amount of paperwork he has to carry around with him, or Word to help with general documents he might have, he will no longer have to carry around his bulky sales catalogue, he is also able to use a calculator on his laptop.

Mobile Phone: A mobile phone, or even better, a smart phone can help him massively with his work and with general activities, it even makes listening to music easier, with a smart phone he is able to call clients and update them on where he is and will be able to inform them if he is going to be late. he is also able to browse the internet on it and take notes as well, there is also a calculator built into it. He is also able to download all his music digitally and and play them off his phone which would save him the hassle of bringing all his cds with him. he's also able to use gps on his smart phone, saving him money on buying one.

Disadvantages for emplying a lot of IT would be that it's very expensive, to buy up to date technology could mean that you will be paying thousands of pounds and they might not always be reliable and are prone to breaking, and if you were to lose any on the job, it will end up costing a lot more than just losing some paperwork.
