Mobile technologies have become cheaper to buy and have greater performance, functionality and capacity than ever before. This can encourage over-complicated products to be used for mobile applications. These will have higher direct costs in maintenance, support or training, and higher indirect costs from the unnecessary complexity of the user experience. This is especially noticeable in the automation of simple, traditionally paper-based, processes. Done well, the use of appropriate mobile technology can pay dividends, but beware the pitfalls.
