- #5 Gaps in translating work Which list are you operating from? Difficult to manage project change Team is disconnected People working on stale info Status from team members is pulling teeth Inefficiencies between team members Tracking, not managing Tools stand apart from systems Gathering metrics is cumbersome Difficulty correcting systemic problems Hard to find when you need them Process changes aren’t followed Painful translation from requirements to actual work. I spend all my time mapping and remapping data Gathering metrics from all over the place. Its a manual and time intensive exercise My metrics, your metrics Managing project change becomes a translation nightmare Where is the project, overall? Separate out the high level from the noise Choose areas that will have the most impact Want to use best practices Hard to find when you need them Cannot correct systemic problems in the team with systemic solutions People need to go out of their way to follow the process Need for more communication /Team is disconnected. People working on stale info From team members – what have I completed? In between team members – can I start work yet? Why don’t those people
- #12 Introducing Visual Studio Team System Visual Studio Team System consists of: Visual Studio Team Foundation an extensible team collaboration server that enables all members of the extended IT team to effortlessly manage and track the progress and health of projects Visual Studio Team Architect, visual designers that enable architects, operations managers, and developers to design service-oriented solutions that can be validated against their operational environments Visual Studio Team Developer, advanced development tools that enable teams to build reliable, mission-critical services and applications Visual Studio Team Test, advanced load testing tools that enable teams to verify the performance of applications prior to deployment The Visual Studio award-winning developer tool forms the core of the Visual Studio Team System and is included in each of the three products listed above Visual Studio Team Suite, bundle of Visual Studio Team Architect Edition, Visual Studio Team Developer Edition, and Visual Studio Team Test Edition Proven process guidance, prescriptive architectural guidance, and solution accelerators that assist organizations in improving the predictability and reliability of delivering mission-critical solutions. Here’s what we’re building… We’ve designed our tools from the ground up to… Reduce the complexity of delivering modern solutions by constructing intuitive user interfaces and baking the process guidance directly into the product Facilitate communication and collaboration among members of a software delivery team through deep integration of features Enable a vibrant partner ecosystem through a set of Web service-based APIs for ISVs and businesses to plug into
- #20 Team Foundation is server software for managing collaboration and assets across teams. Team Foundation includes enterprise-grade change management tools for managing assets and work items. This is not SourceSafe, it’s built from the ground up on the .NET Framework and Web services to support large teams. We’re already using it inside of Microsoft and will roll it out broadly once we ship the product. It includes all the facilities for branching, changesets, merging, diff, etc. that you’d expect. The Work Item tracking system is a productization of the same tool that all of Microsoft already uses to manage bugs and track work items. We’ve integrated with Microsoft Project and Microsoft Excel as well, so that if you’re a casual stakeholder in the project, or just someone who prefers to work in Office, you can do so. The data in Office and the data in Team Foundation are always synchronized. As you work and check in, resolve work items, resolve bugs, etc., the Team Foundation gathers a lot of metrics on your project and developers. This information is stored in a SQL 2005 data warehouse. All of this information can be accessed via SQL Reporting Services. We’ll actually ship 50+ reports in the box, and all the reports have associated Web parts which can be displayed in the Project Portal. The Project Portal is Sharepoint-based. It’s created for every project portfolio so that you can manage developers, source code, and project status.
- #22 Team Architect Edition enables software architects and infrastructure architects to collaborate more effectively on delivering service oriented applciations. We will deliver three major designers in VSTS: The AD: enables you to visually author your Web services and service oriented architectures The LDD: enables you to visually author your network infrastructure The DD: enables you to define hosting relationships between your application design and datacenter design Now, these three designers are great in and of themselves. However, the “secret sauce” of VSTS is that these designers work well with one another. First, the diagrams you author in the AD are always synchronized with code. Most importantly…the architecture you describe in the AD can be immediately validated against the network infrastructure you describe in the LDD. This saves a lot of time when it comes time to deployment as you can have the confidence in knowing that the application you’ve built will, in fact, work in the network topology you’ll need to deploy in. This is what we refer to as “designing for operations”, and it’s a key component of our Dynamic Systems Initiative.
- #32 Team Developer Edition enables advanced developers to verify the performance and quality of the code they write. Static code analysis: think of Static Code Analysis as grammar checking for your code. Compilers check your syntax, similar to spell checkers. But, static code analysis tools analyze the semantic meaning behind your code and can detect performance problems, security errors, and more. This is a productization of tools that we’ve used internally for years. Code profiling analyzes your code as it’s running to give you more information on how your application is running. We’ll actually ship two code profilers in VSTS: a sampling based profiler and an instrumented profiler. A sampling profiler polls your application and retrieves information about it. Once you get that data, you can use the instrumented profiler. The instrumented profiler injects probes into your code at compile time. As your application runs, those probes fire off data which is collected by the profiler. This is a productization of tools we’ve built and used internally for years. Code coverage and unit testing work hand in hand. Unit testing is an attribute based unit testing framework similar to JUnit and NUnit. But, unit testing only tells you how well your code has been tested. It doesn’t tell you how effective your testing is. Code coverage tells you how much of your code has been exercised by unit tests. Optional anecdote about code profiling: Last year, we brought a very large ISV up to Microsoft to profile their code. They used our code profiler after using several others already in the marketplace and were able to see an immediate 10-15% performance gain. We’ve always considered our code profiling tools as one of our competitive advantages. We’re productizing it and putting it in the box for you to use.
- #39 Team Test Edition is load testing software for Web professionals to test the performance capacity of their Web applications and services. Load testing includes a Web test recorder that records interaction between the user and the browser which can then be replayed on a test infrastructure The Load Testing solution itself enables you to customize how you execute distributed load tests on a test infrastructure. Team Test Edition also includes test case management tools for organizing load tests, unit tests, and manual tests in one location. The Load Testing software will work on any HTTP or HTTPS based application, be it .NET Framework-based or not. Third-parties can customize the load testing software to support other protocols.
- #42 A number of partners, from large and small ISVs to large and small Systems Integrators are integrating on top of Visual Studio.
