I love books which go straight to the point and explain you how you can do something step-by-step. And Validating Product Ideas is just like that. It's devided based on problems you're solving during product creating and it suggest you one research technique how you can get feedback from your users. And it describes research techniques really deeply. Only think I wasn't satisfied with was picking the regular research methods, because from the value proposition of the book I expected some new, more guerrilla approach, so if you already know, how to do Usability Study, AB testing, In-depth interviews, Tree Testing, Ethnography this book is not already for you. I would suggest it to Product Owners that never heard about getting feedback from their users and Designers on the beginning of their career.

I love how this book structures each chapter around a key user research question and an ideal method to answer it. For example, there's a chapter to answer "How do people currently solve a problem?" which Sharon addresses by explaining how to set up and run an observation study.

The book is immediately applicable to practice; I found myself referencing earlier chapters in my daily work before I'd even finished reading. (Although I say "finished reading," and I *did* find it worthwhile to read cover-to-cover, the book's introduction says it's not intended to be read cover-to-cover; rather it's structured so that one chapter guides you through the steps of any particular research project.)

The breakdown in the "who are the users?" chapter of common categories of problems with the phrasing of user interview questions is the best guide I've yet encountered for crafting questions that lead to actionable insights. I'm in the process of using the chapters on "What do the users need?" and "What is the user's workflow?" to set up an experience sampling study and diary studies. The final chapter outlines a process for recruiting participants via social media; I'm looking forward to trying it out as a way of finding participants who aren't already familiar with my organization.

I will definitely recommend this book to everyone who wants to get more into the research side of things. Very clear introduction guide to most popular methods, with examples and all the usual caveats like finding participants, getting informed consent, and so on. One of those books you should just have on your bookshelf and look into if you need some inspiration or reminder of certain tools.

Excellent practical guide for getting started and going through the processes that lead to the launching and running of new products. It's a great one to come back to the chapter you need as you do your research.

A light yet dense nice book that covers lean user research technique to answer some questions you might ask on product development phase. the book walks you through several user research techniques to answer questions such as What do people need?, Who are the user?, Can people use the product?.

Author provides step-by-step guide to do each research technique correctly and effectively. I found some repetition on the steps on different techniques, but i supposed it had to be said haha. The book also provides some examples for the tools/documentation that are being used in each research techniques.

The book will be suitable for product people who want to build a product.

When I started reading Validating Product Ideas by Tomer Sharon, I instantly understood what he was trying to do: teach entrepreneurs how to love the problem, not the vision. I’ve been trying to help my clients with this through hands-on, user-research practice. Now I might start assigning reading “homework” from Validating Product Ideas too.

I wrote a more extensive review of this book on The UX Book Club blog.

About a 4.4/5 for me��

Really valuable information. He's right when he says you shouldn't read it cover to cover but just use for reference for what you're currently working on. (This was for a UX book club so I didn't have much of a choice, and as a warning it's a bit of a slog to get through in one go.)

A number of the suggestions I was able to put into practice, as well as a few reminders of best practice to emphasize with my team (such as the the repeated reminders to run a pilot test, please and thank you), and I'm particularly interested in particular in using the lostness metric in the future.

I disagreed on a couple of the minor takes. For example, that you shouldn't use quantitative questions when identifying needs. Quant questions can be hugely helpful for this, not just in contextualizing information, but also giving a sense of how severe an issue is. For example, asking how many times a week someone has to call in for specific information from shelters. If it's once a month, yeah there might be something there, but any new solution would likely more of a hassle than a help. If it's 18 times a day, that's more likely a need that needs to be addressed.

Also minor issue but an MVP is. Literally a "minimal version of a product with the smallest possible feature set." Like it's even in the name. Minimum Viable Product. Though this could also be lack of consistency within the field (or even within a single organization in one past case).

Other takes I heavily endorse. Such as personas are not a research methodology, and their primary use (alongside user stories) is as a communication tool to gain empathy from the product team for the actual users.

I also appreciated the very specific examples and advice, especially around things like expected time for particular analyses when split different ways, artifact templates, or social etiquette during in person interviews that isn't always explicitly taught. Also convenient to have the recommended sample sizes for particular techniques as well (such as the 500 users for the lostness metric or other findability-based quant studies.)

I would be interested to read more about the tie-in with product metrics (KPIs/OKRs), especially on the quantitative side and benchmarking over time.

"One of the hardest things to know in product development is who your target audience is." - Tomer Sharon

If you are about to develop a product or service and ask yourself what people need, this book is for you. Sharon gets straight to the point with clear guidelines about user research designs. In addition, he shares tips and tricks for immediate practice.

The book has 9 chapters: Each of the first 8 chapters answers a specific question product developers have about their users. Then, a step-by-step guide answers each question. This structure allows the reader to read the most relevant chapter without reading the book from start to end.
Chapter 9 is about recruiting participants for research.

And yes, it is hard work to get to know users. User research can also be frustrating, if not hurtful. But Tomer Sharon has valid points about why it should be essential for every business to know their target audience. He is not advocating for using "quick & easy" processes but instead encourages product developers and founders to go "into the field". The author presents a variety of methods and approaches for various situations.

If you choose to read the book from start to finish, you'll find lots of repetition. Some sections are even copied 1:1. I found that irritating at first, but the recurrences make sense if you cross-read the book.

Distills user research into simple and actionable methods based on the higher order question at hand (e.g., "what do people need?", "can people use the product?"). Tomer does not attempt to be comprehensive in technique or strategy, and is silent on the deeper synthesis of insights and design implications beyond answer the question at hand.

Focused and useful as a text or reference for experienced researchers, and an able (if not dry; there's no fluff here) introduction for product-or-designfolk who understand the value of research practice, but don't know how to start.

Along with Steve Portigal's 'Interviewing Users' and Erika Hall's 'Just Enough Research', these three books make up the holy trinity of practical research basics: technique, mindset, and method, respectively. You'll have to look elsewhere for deeper theory or insight into the larger design process itself.

Overall the chapters are well structured, but there's a lot of repetition. It truly wasn't meant to be read from start to finish, as the author outlined in the introduction of the book. I do think that the last chapter (social media participant recruiting) was extremely weak. I expected a well thought through professional approach to effectively recruit participants in a cost efficient way. Instead I thought the approach was quite "spammy" and I'd have my doubts if my or other bigger professional companies would truly consider such approaches. Spamming Facebook groups and pages with screeners? Might do more harm than good for a strong brand...

Reads more like a textbook, but very useful while practicing user research. Great for product managers, product designers, marketing researchers, and user researchers. Would pick this up again the next time I do a deep dive into user research. I especially liked the section about poor interview questions and how to make them better. Everyone could benefit from asking better targeted questions.

In this book, you'll find 8 questions product builders have to answer with how-to guides for every question.

Tomer Sharon provides detailed instructions starting from how to recruit users for each activity, ending with how to analyze the findings.

I’d recommend the book to all product people (managers, designers, builders, founders).

This is a pretty good hands-on-book. It's written with simple and clear explanations of how to work with different design questions in product design. You can easily go back and look up techniques that you can use for specific purposes.

It is a good introduction to user research for those from other fields like product or design. It is written in a format for execution oriented. Hence it can work best when paired with a theoretical foundation, than a sole source.

Admittedly quite useful but any book that states that “observation” can also be referred to as “ethnography” is just perpetuating confusion in the field.

Think it was harder to read on Hoopla, both because it was hard to read the graphics and was harder to flip around to relevant information.

This book is a must read for anyone building a new product/startup or for anyone who already have a product but needs answers from real users. Tomer wrote an easy to read and step by step book with the best user research and product validation techniques. Instead of just showing them he also define which one is best to answer each different question (like "What do people need?", "Do people want the product?", "Which Design generates better results" and many others). For me the detailed step by step and tons of examples to create better questions and observation methods is worth more than gold for any company or startup who wants to really understand its users.

Reads more like a textbook -- would be great for someone practicing UX research to use this as a reference guide. Particularly liked the section on what are bad interview questions and how to change them for the better.
