Improving Work Style (Tool Man)

John currently takes a large diary, address book, a large road atlas, a calculator and a bulky sales catalogue. John could invest in a laptop, where the catalogue could be transferred to an online store, where it may also be easier as he wouldnt have to purchase a new catalogue every time there is a new product line, he could also complete the order form online. He could also save the 2 hours he spends every day completing his administration by inputting the information into the laptop after every client. Due to him investing in a laptop, he may be able to spend friday (usually spent in the office ensuring all administration and sales are handled) being more flexible and seeing more clients or working from home. 
   He would also benefit from buying a GPS, where he would be able to input the clients addresses, so could make sure he was on time, and wouldnt need a large diary. This would also be time saving, as would show the quickest route, and would make sure he was on time for new clients, and might be able to steer him away from the busiest route.
   John could buy a PDA (personal digital assistant), where John could input all his information and replace with his large diary. It is much smaller and more conveniant than a bulky diary, and he wouldnt have to take a calculator with him. He could also keep track on what clients are ordering, and when they are going to be in stock.
  John investing in a mobile phone means he would not need to carry an address book around with him and wouldnt have to make sure he had numerous small coins for pay phones. He could also give it to all clients as a business number for if they ever had any enquiries. If John wanted to upgrade to a smartphone, he could do numerous things on there to save him carrying around lots of technology, such as GPS, calculator, phone book, etc.
The possible disadvantages to John employing lots of technology is that it could be very costly, especially if he had to replace any of it, or if anything got damaged. Due to John not using technology along with his work for 20 years, he could have problems with setting up all the ICT, or understanding how to use it to its best ability and benefit his working style. If John does not have the right software on his laptop when inputting the clients personal infomation, he could be attacked by hackers, so to protect the clients he has to make sure he tries to prevent this, and use the apporopriate software.
