The system modelling tool can be avoided since most established SysML modelling tools support the synchronisation of requirement elements with their counterparts in an external requirements management tool repository, including traceability information. By representing requirements in the system model, it is.

NoteSome versions of Visual Studio support dependency validation and read-only versions of code maps for visualization and modeling. To see which editions of Visual Studio support this feature, see. Understand and communicate information about the systemThere is no prescribed order for using the Visual Studio modeling diagrams, so you can use them as they fit with your needs or approach. Usually, teams revisit their models iteratively and frequently throughout a project. Each diagram offers particular strengths to help you understand, describe, and communicate different aspects of the system under development.Dinner Now and Lucerne communicate with each other and with project stakeholders by using diagrams as their common language. For example, Dinner Now uses diagrams to perform these tasks:.Visualize existing code.Communicate with Lucerne about new or updated user stories.Identify changes that are required to support new or updated user stories.Lucerne uses diagrams to perform these tasks:.Learn about the Dinner Now business process.Understand the design of the system.Communicate with Dinner Now about new or updated user requirements.Document updates to the system.The diagrams are integrated with Team Foundation Server so the teams can plan, manage, and track their work more easily. For example, they use models to identify test cases and development tasks and to estimate their work.

Lucerne links Team Foundation Server work items to model elements so that they can monitor progress and make sure that the system meets the users' requirements. For example, they link use cases to test case work items so they can see that use cases are fulfilled when all the tests pass.Before teams check in their changes, they validate the code against the tests and the design by running builds that include dependency validation and automated tests. This helps make sure that the updated code does not conflict with the design and break previously working functionality. Identify Changes to the Existing SystemDinner Now must estimate the cost of meeting the new requirement.

This depends partly on how much this change will affect other parts of the system. To help them understand this, one of the Dinner Now developers creates these maps and diagrams from existing code: Map or diagramShowsCode mapSee:-Dependencies and other relationships in code.For example, Dinner Now might start by reviewing assembly code maps for an overview of the assemblies and their dependencies. They can drill into the maps to explore the namespaces and classes in those assemblies.Dinner Now can also create maps to explore particular areas and other kinds of relationships in the code. They use Solution Explorer to find and select the areas and relationships that interest them.Code-based class diagramSee.Existing classes in codeFor example, the developer creates a code map. She adjusts its scope to focus on the areas that will be affected by the new scenario. These areas are selected and highlighted on the map:Namespace code mapThe developer expands the selected namespaces to see their classes, methods, and relationships:Expanded namespace code map with visible cross-group linksThe developer examines the code to find the affected classes and methods.

To see the effects of each change as you make them, regenerate code maps after each change. See.To describe changes to other parts of the system, such as components or interactions, the team might draw these elements on whiteboards. They might also draw the following diagrams in Visual Studio so that the details can be captured, managed, and understood by both teams: DiagramsDescribesCode-based class diagramSee.Existing classes in code.Keep Code Consistent with the DesignDinner Now must make sure that the updated code stays consistent with the design. They create dependency diagrams that describe the layers of functionality in the system, specify the permitted dependencies between them, and associate solution artifacts to those layers. DiagramDescribesDependency diagramSee:-The logical architecture of the code.A dependency diagram organizes and maps the artifacts in a Visual Studio solution to abstract groups called layers. These layers identify the roles, tasks, or functions that these artifacts perform in the system.Dependency diagrams are useful for describing the intended design of the system and validating evolving code against that design.To create layers, drag items from Solution Explorer, code maps, Class View, and Object Browser.

To draw new layers, use the toolbox or right-click the diagram surface.To view existing dependencies, right-click the dependency diagram surface, and then click Generate Dependencies. To specify intended dependencies, draw new dependencies.For example, the following dependency diagram describes dependencies between layers and the number of artifacts that are associated with each layer:Dependency DiagramTo make sure that conflicts with the design do not occur during code development, the teams uses dependency validation on builds that are run on Azure DevOps. They also create a custom MSBuild task to require dependency validation in their check-in operations. They use build reports to collect validation errors.See:.General Tips for Creating and Using Models.Most diagrams consist of nodes that are connected by lines. For each diagram type, the toolbox provides different kinds of nodes and lines.To open the toolbox, on the View menu, click Toolbox.To create a node, drag it from the toolbox to the diagram. Certain kinds of nodes must be dragged onto existing nodes. For example, on a component diagram, a new port must be added to an existing component.To create a line or a connection, click the appropriate tool in the toolbox, click the source node, and then click the target node.

Some lines can be created only between certain kinds of nodes. When you move the pointer over a possible source or target, the pointer indicates whether you can create a connection.Plan and track workVisual Studio modeling diagrams are integrated with Team Foundation Server so that you can plan, manage, and track work more easily. Both teams use models to identify test cases and development tasks and to estimate their work. Lucerne creates and links Team Foundation Server work items to model elements, such as use cases or components. This helps them monitor their progress and trace their work back to the users' requirements. This helps them make sure that their changes continue to meet those requirements.As their work progresses, the teams update their work items to reflect the time that they spent on their tasks. They also monitor and report status on their work by using the following Team Foundation Server features:.Daily burn down reports that show whether they will complete the planned work in the expected time.

They generate other similar reports from Team Foundation Server to track the progress of bugs.An iteration worksheet that uses Microsoft Excel to help the team monitor and balance the workload between its members. This worksheet is linked to Team Foundation Server and provides focus for discussion during their regular progress meetings.A development dashboard that uses Office Project to keep the team informed about important project information.See:.Test, Validate, and Check In CodeAs the teams complete each task, they check their code into source control and receive reminders from Team Foundation Server, if they forget. Before Team Foundation Server accepts their check-ins, the teams run unit tests and dependency validation to verify the code against their test cases and the design. They use Team Foundation Server to run builds, automated unit tests, and dependency validation regularly. This helps make sure that the code meets the following criteria:.It works.It does not break previously working code.It does not conflict with the design.Dinner Now has a large collection of automated tests, which Lucerne can reuse because almost all still apply. Lucerne can also build on these tests and add new ones to cover new functionality.

Both also use Visual Studio to run manual tests.To make sure that the code conforms to the design, the teams configure their builds in Azure DevOps to include dependency validation. If any conflicts occur, a report is generated with the details.See:.Update the System Using Visualization and ModelingLucerne and Dinner Now must integrate their payment systems. The following sections show the modeling diagrams in Visual Studio help them perform this task:.See:.Visualize Existing Code: Code MapsCode maps show the current organization and relationships in the code. Items are represented by nodes on the map, and relationships are represented by links. Code maps can help you perform the following kinds of tasks:.Explore unfamiliar code.Understand where and how a proposed change might affect existing code.Find areas of complexity, natural dependencies or patterns, or other areas that might benefit from improvement.For example, Dinner Now must estimate the cost of updating the PaymentProcessing component.

This depends partly on how much this change will affect other parts of the system.

In the past couple of weeks, I’ve been asked about methods to capture and track important or essential performance parameters, generally referred to as “technical measures” in a model-based environment. This post is dedicated to understanding technical measures and how to identify them in the operational and system architecture.In my research on this topic, I have found two general approaches to key performance parameter (KPP) identification and management. One approach is documented in the (Garry Roedler and Cheryl Jones, Dec 2005, INCOSE-TP-2002 -020-01). The INCOSE publication was authored in 2005 and based on a set of Department of Defense definitions in use at the time. Since this publication, the Department of Defense management of technical measures has evolved, introducing new terms and definitions. The latest thinking by the Department of Defense can be found on the Defense Acquisition University (DAU) writings accessible through the.
