Since this is the first book on K2 blackpearl, you will find a broad range of topics in this book, from the market in which K2 blackpearl is aimed to the architecture of the platform, from how to approach process design to developing your own custom user manager.

The first part of the book is meant for everyone and provides an understanding of K2 blackpearl and where it fits in the marketplace. It is included to provide a framework for thinking about various aspects of process-driven applications, including how they differ from business process management techniques; identifying processes in your company to automate, the different pieces that make up a process; measuring the success of your efforts; and finally shifting your company's culture in the direction of process efficiency. This section may be the only section you need to read if you are sponsoring a process improvement effort in your company. If you are responsible for leading the effort, make sure to read Chapters 3 and 4.

The other parts are meant to provide details on how to effectively deploy and use K2 blackpearl and include a broad range of topics. Read what you are most interested in, but also make sure to read Chapter 8, which will give you a great foundation to start designing processes with K2 blackpearl. Chapter 14 is also recommended for everyone because it provides an overview of the available K2 Designers and how you can share projects among them.

If you are a developer, you may be tempted to flip through the book looking for code, and you will find some, but we also recommend reading much of the rest of the book to learn how the API and the K2 platform extensions fit within the overall process-driven application environment. Pay particular attention to Chapter 22 and the Appendix, which may save you hours of coding or give you a no-code solution to something that you may have thought would take hundreds of lines of code to accomplish.

If you are an administrators, focus on Parts II and IV, but also take a look at the other chapters to gain an understanding of how your users will be using K2.

K2 blackpearl is the main subject of this book, although we devote an entire chapter, Chapter 23, to the add-on product K2 connect to give you an understanding of how to bring SAP data into your processes. We also talk a bit about K2 blackpoint, particularly in the SharePoint chapters. Since K2 blackpoint is built on the K2 blackpearl foundation, many of the same concepts apply to that product as well, but we do not point out the differences between K2 blackpearl and K2 blackpoint. For that information browse to www.k2.com.

We recommend that you approach this book in parts and perhaps read or reference each part differently. If you are working on a team, each member of the team may find one part more interesting to them than the other sections; that is expected and is how we designed the book.

Last but not least, we've combed through the various K2 blog entries available at the time of this writing to give you what we think are some of the greatest tips and tricks out there for working with K2 blackpearl in the appendix. Of course you could go out and find these yourself (and we give you the links to do so), but we thought that including the best of the best right here in the book would give a complete picture of K2 blackpearl. Also take a look at the "Other Resources" section later in this introduction.

There are some pieces of this book that you can sit down and read without needing a computer or access to K2 blackpearl at all, but much of this book requires you to have access to K2 blackpearl and the supporting applications as well. Whenever we talk about designing processes, we do so in the context of the K2 Designer for Visual Studio. To install this component you will need Visual Studio 2005. Support for Visual Studio 2008 may be available by the time this book is published, so look for that on www.k2.com.

For the server pieces of the platform, you will need a Windows Server 2003 environment (virtual or otherwise) and the additional components required by the K2 server. For detailed information about the K2 blackpearl requirements see the K2 blackpearl Getting Started guide available on the customer portal. For access to the portal you need a customer account, which may be obtained by contacting your nearest K2 representative. If you don't know who that is, browse to www.k2.com and click Contact. Evaluation licenses are available for K2 blackpearl.

There are a great number of resources available to learn more about K2 blackpearl. Here we'll give you some pointers.
