This book is brilliant for getting questions answered. I have a small business but it is national and I wanted to find out about apps. I spoke to a few developers and mainly found that they wanted to sell me their services. I almost jumped, but then I realised my depth of knowledge about apps was minimal. I didn't even know if my app idea would be useful at all! Oh yeah, sure I could get it built, but would it do what I needed it to do for my business. Very much a Poor App I suspect.
Simon's book is not focused on selling. It's focused on giving you the information you need to make the right decisions, before you spend out tons of cash. And then walks you through the process to make sure your app is truly your app.
Well worth the investment.
