This gets down to the unavoidable reality that "Software is not Construction". Software estimation is a very risky and difficult task. Johanna offers many strategies to deal with this issue, based on her hard-won experience over several years. I have wrestled with this problem throughout my career and now have some new tools to help with dealing with managers who want fixed time, scope, and cost quotations.
The style of the book is clear and feels very honest. I would definitely recommend this book!

This book is disappointing. Full of generic statements and links to buy other books by same author.
Finally I bought these books after this one:
Estimating Software Costs: Bringing Realism to Estimating
Software Estimation: Demystifying the Black Art (Developer Best Practices)
How do you deal with requests to estimate what will be delivered by what date? Johanna Rothman’s excellent book Predicting the Unpredictable gives you answers.
The title basically gives it away: how do you predict the unpredictable? Rothman gives clear recommendations on how to make, revise, and communicate estimates using proven techniques.
The book is filled with loads of good quotes:
* “Since software is about learning, and we rarely, if ever, do the same project twice, we are always estimating the unknown.”
* “In many ways, estimating project budgets or dates for agile projects turns out to be irrelevant.”
* “Some managers want you to estimate the budget as well as the date. And now, you’re off into la-la land.”
Many readers will find the final chapter most rewarding: Troubleshooting. Rothman explains the dangers of the common practices of multi-tasking and team switching, how to use spikes, how to estimate testing time, and the three big estimation traps.
A must read for product leaders, product managers, and project managers.
