software architecture software architects IT project schedule plan staff project budget software development techniques estimation errors estimation technique planning parameters sources requirements Software estimation project manager software architects Carefully written books are not the rule in computing where the speed of developments often overtakes an author while he still broods over his topic. Much in IT is , for this reason, written in great haste. The present book is a rare exception to this rule. It is the outcome of many years of experience and repeated verification of the techniques presented. Software estimation, i.e. the informed guess at how long some task or project will take and what kind of effort is required, is a necessary prerequisite for steering a projectUnless a project manager has some idea of the schedule ahead, he is not in a position to plan and staff a project, let alone provide the necessary budget. But how does one make reasonable assumptions about an uncertain future? The key, at least in software development, is estimation. Estimation is not a black art, insists the author of the present book, but there are techniques which help making informed and well reasoned assumptions about the future. These techniques are what the book is about. The book has three partsIt starts by examining the the critical estimation concepts. I have in particular enjoyed reading about where estimation errors usually come from. The core of the book is part two, which is devoted to estimation techniques. At their very foundation is 'count, compute, judge', not guess. The last part discusses the various estimation challenges, which include converting estimates into planning parameters, or political issues resulting from contentious estimates. Where much praise is due some criticism is also in order. If there is one aspect of estimation which I think remains somewhat out of focus then it is the question of the sources of requirements. The book, in its larger part, assumes that requirements are given in a form which is accessible to estimation. In actual practice this is not usually the case. And even if requirements are available, estimation usually requires that these requirements should be brought into a formal form which allows one to submit them to 'counting, judging, computing'. There are few hints in this book regarding these two fundamental questions. The first might be delegated to books on requirements engineering, while the second, I think, should have been included, at least in the form of extended examples (the examples of the book are suitably simple for the purpose of the exposition, they remain sub-ideal as applicable templates). The art of estimation is one of the tools that should be in any architects toolbox. Unfortunately, this tool is often forgotten in introductions to (pragmatic) software architecture. As I know no better book on the topic of estimation, I think this book is a must-have for all software architects. Or should I sayA must-read!

Descrizione articolo

Riassunto

Often referred to as the “black art” because of its complexity and uncertainty, software estimation is not as difficult or puzzling as people think. In fact, generating accurate estimates is straightforward—once you understand the art of creating them. In his highly anticipated book, acclaimed author Steve McConnell unravels the mystery to successful software estimation—distilling academic information and real-world experience into a practical guide for working software professionals. Instead of arcane treatises and rigid modeling techniques, this guide highlights a proven set of procedures, understandable formulas, and heuristics that individuals and development teams can apply to their projects to help achieve estimation proficiency.
Discover how to:

• Estimate schedule and cost—or estimate the functionality that can be delivered within a given time frame
• Avoid common software estimation mistakes
• Learn estimation techniques for you, your team, and your organization * Estimate specific project activities—including development, management, and defect correction
• Apply estimation approaches to any type of project—small or large, agile or traditional
• Navigate the shark-infested political waters that surround project estimates

When many corporate software projects are failing, McConnell shows you what works for successful software estimation.
