The Digital Seeker is a good book if you want to understand the mindset of your customers for a digital product. This type of product is different than many others and as such requires different considerations from the people developing them. This book provides a good blueprint for how to develop a digital product and be successful in digital business

Good book: interesting content, easy to understand even if you're not an IT professional.
Moreover, Raj K. De Datta explains very well the problem you can face and illustrates them with practical examples.
I recommend! This book is one of my favorite in this domain. I used and quoted it a lot during my pieces of training.
