Grigori Melnik: Thoughts on Agile Software Engineering and Beyond : intro

Acceptance Test Engineering Guide, volume 1 BETA2 release

gmelnik — Wed, 01 Jul 2009 03:30:00 GMT

Today I am pleased to announce the release of the beta2 of the first volume of our Acceptance Test Engineering Guide. We are getting closer to “done”.

As it became apparent that the primary reader personas for each part in the original guide (that was released as beta1) were different and the size of the guide was approaching 800 pages, we decided to split it into 3 volumes. It allows us to ship Volume I sooner while finishing Volume II and III. Incremental delivery for the win!

Based on the first round of reviews, Volume I has undergone some serious rewriting (especially, the Gating model, which is now called the Acceptance Process Model) and the entire new chapters were added (Part II – Perspectives on Acceptance).

Here’s the current structure of the guide:

Volume I provides an overview of the acceptance process and how acceptance testing and other key practices fit into the process. This volume is intended to be read from beginning to end. It is subdivided into three main parts:

Part I – Thinking about Acceptance explains six mental models that are useful when thinking about the acceptance process.

Chapter 1 The Acceptance Process
Chapter 2 Decision-Making Model
Chapter 3 Project Context Model
Chapter 4 System Requirements Model
Chapter 5 Risk Model
Chapter 6 Doneness Model

Part II – Perspectives on Acceptance describes the acceptance process from the perspectives of key stakeholders in two different kinds of organizations: the Information Technology Department in a business and the Product Development Company. Most readers involved in the acceptance process should find some commonality with at least one of the roles describes.

Chapter 7 Business Lead’s Perspective
Chapter 8 Product Manager’s Perspective
Chapter 9 Test Manager’s Perspective
Chapter 10 Development Manager’s Perspective
Chapter 11 User Experience Specialist’s Perspective
Chapter 12 Operations Manager’s Perspective
Chapter 13 Solution Architect’s Perspective
Chapter 14 Enterprise Architect’s Perspective
Chapter 15 Legal Perspective

Part III – Accepting Software introduces the practices that are necessary for planning the acceptance process, for performing acceptance testing and for improving the acceptance process.

Chapter 16 Planning for Acceptance
Chapter 17 Assessing Software
Chapter 18 Managing the Acceptance Process
Chapter 19 Streamlining the Acceptance Process

Volume II is a collection of what we call thumbnails that describe the practices introduced in Volume I in more detail. A thumbnail is a short overview of a practice that explains what it is, when you may want to use it, the risks that it mitigates, and an overview of how to perform the practice. Thumbnails also include a list of references to papers, books, and other resources that provide more complete descriptions of the practices in question. The main purpose of a thumbnail is to describe a topic well enough to provide an overview, serve as a mental reminder for someone who has used the practice on how to do it, and give someone unfamiliar with the practice enough information about the practice and its applicability to determine if they want to learn more about it. Some of these topics and practices have entire books written about them that describe the concepts in greater detail and depth than this guide could possibly do. Volume II is intended to be used as a reference; most readers will not read it from beginning to end.

Volume III. This volume is a collection of sample artifacts generated by applying different practices in a fictional but realistic situation for the fictional company Global Bank. These artifacts are embedded in a series of case studies of what the Global Bank team may have produced while building the application. The case studies provide some context to the individual artifacts. They also provide cross-references to the practices described in Volume II. The artifacts are intended to be used as way to learn more about how to perform a practice; they can also be used as templates for your own artifacts.

As always, we look forward to your feedback! Feel free to submit it through the Codeplex site (Issue Tracker or Discussion Forum) or simply email it to me.

Just Released – Hands-on Labs for Enterprise Library 4.1 and Unity 1.2

gmelnik — Thu, 19 Mar 2009 02:38:00 GMT

I know it’s easy to get lost in the plethora of announcements and buzz from MIX’09, but today we are releasing a set of hands-on labs for all the application blocks in Enterprise Library. We believe that this valuable release will not go unnoticed by the community of devoted EntLib users and want to take this opportunity to highlight it for new users as well. After all, the labs are meant to help you get up to speed with EntLib.

This release includes a refresh of the labs for the following blocks:

- Caching Application Block

- Cryptography Application Block

- Data Access Application Block

- Exception Handling Application Block

- Logging Application Block

- Security Application Block

There are also two entirely new hands-on labs covering Interception and Dependency Injection with Unity. The Validation Block hands-on lab was released back in December and the overwhelmingly positive feedback we’ve received on it encouraged the team to produce the rest.

You can download the entire set in both C# and Visual Basic .NET: Hands-on Labs for Enterprise Library 4.1
If you prefer to download the Unity lab as a standalone, it’s also available: Hands-on Labs for the Unity Application Block 1.2

You can do them in any order. They will guide you through common scenarios of using EntLib in various application contexts. Some labs go into advanced topics and you may want do them a couple of times. Also, don’t be shy about improvising and departing from the scenarios written in the lab instructions.

The labs may also be of value to trainers and academics, since they can be used as teaching aids in the classes devoted to Enterprise Library specifically or in courses on Component-Based Software Engineering, Enterprise Application Development, and Aspect-Oriented Programming.

With this release, the EntLib team reiterates its commitment to enhancing learnability and increasing ease of use of Enterprise Library. Please, try them. Whether you love them or feel frustrated (especially if you feel frustrated), please send us your feedback.

Enterprise Library FAQs wiki now open

gmelnik — Wed, 11 Feb 2009 06:13:01 GMT

Greetings, the Enterprise Library user community!

Today the patterns & practices EntLib team together with the EntLib support team from Avanade is pleased announce the Enterprise Library Frequently Asked Questions (FAQs) wiki. We’ve done a sweep of discussion topics through the Codeplex site and our mailboxes and distilled a collection of tips, tweaks, pointers and trouble shooting methods to most frequently asked questions. Check it out!

This is a part of our continuing effort to improve learnability and ease of use of the Enterprise Library.

Importantly, this is a live wiki, not a static document (though if you prefer a printable version, we’ve made one available too). Feel free to comment on any of the answers with your additional suggestions or tricks you want to share. Also, if you have encountered the same question many times and you know how to answer but do not see it on the list, go ahead, add it. Please make sure your answers are meaningful and helpful (an easy way to determine if they are, is whether somebody had thanked you for those answers previously :)

intro

Hello, and welcome to my blog. I've posted an entry on TDD earlier today and completely forgot to introduce myself. Let me do it properly now....

I am Grigori Melnik, a Senior Technical Product Planner with Microsoft patterns & practices. My current portfolio includes:

Enterprise Library, a collection of application blocks designed to assist programmers with common enterprise development challenges (like data access, caching, validation, logging, security, policy injection etc.)
Guidance Automation Extensions (GAX), a runtime for guidance packages, such as those included in Software Factories, for automating key development scenarios from within the Visual Studio),
and The Guidance Automation Toolkit (GAT), an authoring extension to Visual Studio for guidance packages.

I've taken over these from Tom Hollander, the father of EntLib, who's done a fantastic job at taking EntLib to its current high levels of popularity (over 600,000 downloads in 2 years and a solid base of customers standardising their development on EntLib). Though Tom has embarked on a new adventure back home in Sydney, he is still very much connected and involved with EntLib and EntLib Contrib communities. I am glad I can lean on his sholder - thanks, Tom!

In addition, I am involved with researching and revamping Microsoft Solutions Framework (MSF) and its agile instance. One of the tasks is to reconcile the rich body of engineering practices guidance with the MSF process guidance (not a trivial task which probably deserves a separate blog entry).

I'd like to mention and thank colleagues of mine who made my "inauguration" to p&p smooth and painless (so far :): Shaun Hayes, Rick Maguire, Wojtek Kozaczynski, Per Von Nielsen, J.D. Meier, Bill Loeffler, Don Smith, Glenn Block, Andrew Delin, Steve Elston, Mo Al-Sabt, Peter Provost, Ajoy Krishnamoorthy, Chris Tavares, Dmitri Ossipov, Victor Aprea, Bob Brumfield, Kim LaBreck.

They, along with many others, form a great fountain of knowledge and I am honoured to be a part of this talented and capable team!
