2 Creating a new project Select traditional template and click OK. The Project Properties window opens as shown in the figure bellow. Software Requirement Specification and Rational RequisitePro2

3 Creating a new project Enter the name of the project, select a directory, select a database, and optionally provide a description. Use the built-in Microsoft Access database. This is also the location where you would select a suitable SQL Server or Oracle solution. Click Properties to define the login and database identities. Software Requirement Specification and Rational RequisitePro3

4 Packages Once the project template has been copied into your new document, a window similar to the one shown in the figure below appears. Software Requirement Specification and Rational RequisitePro4

5 RequisitePro explorer window The figure below shows a document with the software requirements section expanded. Software Requirement Specification and Rational RequisitePro5

6 Project packages The packages within a RequisitePro project are used to organize the different components in the project. Packages can contain one or more of information: Requirements: the main data type in the project. Documents: based on a template, a bare document or the requirements list. Views: views, based on separate queries, of the list of requirements. For example, in the traditional project template there are three packages used to record different requirement information: Software requirements: the final list of requirements that are used for the project. Features and vision: the list of features for the project. Stakeholder requests: the list of requests for features from stakeholders. Software Requirement Specification and Rational RequisitePro6

7 Creating a new package To create a new package to help track developer requirements in the project: Right-click in the explorer and select New > Package or select the same option from the File menu. A window opens, as shown in the figure in next slide. Give the package a name. You're creating a Developer Requirements section so enter Developer Requirements into the Name field. In the Description field, enter Requirements specified by the developer based on stakeholder and user requirements. Software Requirement Specification and Rational RequisitePro7

8 Package properties Software Requirement Specification and Rational RequisitePro8

9 Creating requirements within RequisitePro Start by building a list of requirements. The steps below show you how to add the first of the recipe database requirements to the project; add the other three using the same method. To create the first recipe database requirement: Right-click within the tree and select New > Requirement, or select the same menu option from the main File menu. A window like the next figure opens. Software Requirement Specification and Rational RequisitePro9

10 Creating requirements within RequisitePro (cont…) Specify the requirement type. This is a notional marker that highlights the requirement as a specific type but has no bearing on where the requirement is stored. The type affects what attributes are stored with the attribute and ultimately that information is used in queries and views to link and trace the sequence and source of information through the system. For the purposes of this walk through, use the Software Requirement type. Give the requirement a name. This should be enough to identify the item within the system. Enter Recipe Entry in the Name field. You can also attach a more detailed description in the Text field. Cut and paste the text “ The user should have the ability to enter a recipe into the database into this field.” Software Requirement Specification and Rational RequisitePro10

11 Requirement properties All requirements are recorded within a folder. This can either be the root folder (not generally recommended) or one of the packages. Because you are creating basic software requirements at this stage, click Browse and select the Software Requirements folder. Software Requirement Specification and Rational RequisitePro11

12 Adding further requirements Repeat this sequence with the remaining requirements from the list, as outlined in this table. All the requirements should be stored within the same Software Requirements folder and all should be of the Software Requirement type. NameText Recipe data A recipe consists of the recipe name, a number of servings, a subtitle/description, a list of ingredients and a list of methods. Recipe search The user should be able to search for a recipe by name, description or ingredients. Recipe scaling The user should be able to change the number of servings for a recipe and have the ingredient quantities re-calculated. Software Requirement Specification and Rational RequisitePro 12

13 The final list of requirements The list should look like the one shown in the figure bellow. Software Requirement Specification and Rational RequisitePro13

14 Adding further requirements You can see from the previous figure that each requirement is given a unique reference number. These numbers are used to help track and trace requirements through the system. Software Requirement Specification and Rational RequisitePro14

15 Alternative requirement types The project template you are using includes a number of pre-defined requirement types: Requirement types define the attributes and other information that is stored with a requirement in the database. Requirement types are configured on a project-by- project basis or within a project template. Software Requirement Specification and Rational RequisitePro15

16 Add or change requirement type: Project properties To add or change the type definitions: Open the properties for the project either by right- clicking on the project and choosing Properties or by double-clicking on the root project. A project properties window appears like the one shown in the figure bellow. Software Requirement Specification and Rational RequisitePro16

17 Add or change requirement type: Requirement types tab Click the Requirement Types tab. Software Requirement Specification and Rational RequisitePro17

18 Add or change requirement type: The requirement types tab To add a new type, click the Add or edit an existing type. You can see from the previous figure that a Developer Requirement type has been added. The basic properties for this type are shown in the figure below. Software Requirement Specification and Rational RequisitePro18

19 Add or change requirement type: alternative requirement types Duplicate the information in the previous window to create the Developer Requirement type. The color and style are used when viewing the requirements in reports and documents so you can use this to help identify the type. Software Requirement Specification and Rational RequisitePro19

20 Requirement attributes Flowing is a list of the attributes defined within the project for the Software Requirement: Priority: High, Medium or Low. Type: the type of requirement (usability, performance, etc). Status: whether the requirement has been approved or incorporated into the project. Difficulty: a rough guide to the difficulty that would be experienced to achieve the requirement. Stability: a guide to the stability of the requirement within an active project. Software Requirement Specification and Rational RequisitePro20

21 Requirement attributes (cont…) Risk: a guide to the risk associated with implementing the project. For example, there might be a high developmental risk if the requirement would require changes to other parts of the system (thereby reducing stability). Enhancement Request: the information sourced from a Rational project if this RequisitePro project is part of a Rational project. Defect: generated by a Rational project during defect management/testing. Contact Name: for the source of the requirement. Obsolete: an indication of whether the requirement is obsolete. Software Requirement Specification and Rational RequisitePro21

22 Specifying the attributes for a requirement type Add a development team field to the Developer Requirement type: Open the project properties. Change to the Attributes tab (shown in the figure in the next slide) and then select the Developer Requirement type from the window. A list of the attributes currently defined for the type will shown. Software Requirement Specification and Rational RequisitePro22

23 Specifying the attributes for a requirement type Software Requirement Specification and Rational RequisitePro23

24 Adding an attribute to a requirement type Click Add. Attributes have a label (the field name you'll populate when you create a requirement), a type, and an optional list of values that are used within a popup or list. The type is a field type just as in a database and can be an integer, floating point, text string, date, time, URL or a list, either single or multiple selection. Select the List (Single Value). Populate the list using the information shown in the figure in the next slide. Use Return to separate the values. Software Requirement Specification and Rational RequisitePro24

25 Adding an attribute to a requirement type Software Requirement Specification and Rational RequisitePro25

26 Creating requirement documents If you select to generate the requirements in Word, it is probably a good idea to generate and record all requirements directly within Word, although it's certainly not a requirement. To generate requirements from within a Word document: Generate a new document, or open an existing document if one was created as part of an existing project template. To create a new document, select File > New > Document or right-click on the tree view of the project and select the same options. A window opens as shown in the figure in the next slide. Software Requirement Specification and Rational RequisitePro26

27 Document properties window Software Requirement Specification and Rational RequisitePro27

28 Creating requirement documents Enter a name for the document (as it appears in the project) and provide a description of what the document contains. You'll be using a document for your Developer Requirements specification so name the document accordingly. As you can see from the sample, this document was created in a new package that has not been created yet, so create it in the root package. For the document type, select the Software Requirements specification. This creates a document using the corresponding Word template. Click OK to create the document and open the template within Word. Software Requirement Specification and Rational RequisitePro28

29 Populating the document Software Requirement Specification and Rational RequisitePro29

30 Adding requirements from within Word A new toolbar is available within Word when you are editing a RequisitePro document (see the figure below). You'll need this― or the RequisitePro menu― as you create requirements directly in the document. Software Requirement Specification and Rational RequisitePro30

31 Adding requirements from within Word (cont…) To create a requirement within the document: Enter the text description for the requirement directly into the Word document. Enter “The Database will hold information about the recipe, recipe ingredients and recipe method” for this example. Select the text you just typed into the document and then click New Requirement (the first square bracket ([]) button), or select New Requirement from the RequisitePro menu. Enter a name for the requirement, specify the requirement type, and ensure that the Package and Location information within the requirement properties are correct (see the figure in next slide). These last two properties should automatically be populated based on the location of the document you are editing. Software Requirement Specification and Rational RequisitePro31

32 Adding requirements from within Word (cont…) Software Requirement Specification and Rational RequisitePro32

33 Adding requirements from within Word The document text you selected is replaced with the requirement text - specially tagged within the document so that it can be updated by RequisitePro. Meanwhile, the text you selected is submitted into the RP database. Note that the item is marked as pending until you save and close the document within Word. Part of the save process imports all of the information into the RequisitePro database. Software Requirement Specification and Rational RequisitePro33

34 Importing an existing requirements document To import an existing document into a project: Click File > Import in RequisitePro. Select the Microsoft Word Document radio button and use the browser to locate the document you want to import. To parse the document contents and import requirements into the project, select Requirements only. To import the requirements and then add the document as a document within the project, select Requirements and document. Alternatively, use RequisitePro to trace and track changes to any Word document that might be related to the project. Either way, select Document only. Software Requirement Specification and Rational RequisitePro34

35 Importing an existing requirements document (cont…) Click Next. If you've chosen either of the Document options, then you need to specify the same document options as if you were creating a new document, such as the document name, package location, and document type. Click Next to continue the import process. If you have opted to import requirements and parse the contents, the Import Wizard window appears as shown in the figure in next slide. Software Requirement Specification and Rational RequisitePro35

36 Importing an existing requirements document (cont…) Software Requirement Specification and Rational RequisitePro36

37 Importing an existing requirements document (cont…) Specify how the system parses the content. Use keywords to identify paragraphs and sentences that define requirements and text delimiters, or use Word styles to identify the requirements in the source document. Once you've selected the system to use, click Next. You'll be asked to approve each matched requirement. Select Yes to all to accept all of the matching requirements once you have verified the basic layout. Software Requirement Specification and Rational RequisitePro37

38 Exporting requirements into a Word document To generate a Word document based on the database contents, click File > Export. You must first choose a View from the explorer to select which requirements are exported into the document. Views are discussed next. Software Requirement Specification and Rational RequisitePro38

39 Views Views in RequisitePro use standard query techniques on the database of requirements to show information and relationships. Each view is composed of the query that generates the information to be displayed and the view type. There are four predetermined formats for viewing the information as follows: Traceability Matrix: a matrix table, showing the relationship between two requirements lists. For example, you might want to show the relationship between the stakeholder requests and the main software requirements. Software Requirement Specification and Rational RequisitePro39

40 Views (cont…) Traceability Tree (Traced into): a tree showing how requirements relate to the specified requirement. For example, you might want to show a tree that describes how stakeholder, developer, and other requirements related to the main software requirements. Traceability Tree (Traced out of): a tree showing the requirements traced from the specified requirement type. For example, you might want to show all the requirements traced from a stakeholder request. Attribute Matrix: a simple table of requirements and their attributes. Software Requirement Specification and Rational RequisitePro40

41 Creating a new view Views can be created anywhere within the project structure, but typically they are created to show specific information within a package. These packages can either be those relating to specific requirement types, as in Stakeholder Requests or Developer Requirements, or they can be packages specially designed to collate and view information. To create a new View: Right-click anywhere in the tree view and click New > View or select the same option from the File menu. The view properties window will be shown as shown in the figure in the next slide. Software Requirement Specification and Rational RequisitePro41

42 Creating a new view (cont…) Software Requirement Specification and Rational RequisitePro42

43 Creating a new view (cont…) You're creating a simple Attribute Matrix view for the Developer Requirements type created earlier in this tutorial, so name the view All Developer Requirements and for the description, enter Developer Requirements attribute view. Make sure the Developer Requirements package has been selected. Select Attribute Matrix as the View Type. Select Developer Requirement for the Row Requirement Type. This option selects which requirement types to show within the view. Click OK. Once the view has been created, RequisitePro explorer changes to this view as shown in the figure in next slide. Software Requirement Specification and Rational RequisitePro43

44 Creating a new view: the RequisitePro explorer Software Requirement Specification and Rational RequisitePro44

45 View queries Queries within a view allow you to customize the information that is being displayed. To create a view that displays only the high-priority developer requirements: Right-click anywhere in the tree view and select New > View or choose the same option from the File menu. Name the view High Priority Developer Requirements. Select the Developer Requirements package. Select Attribute Matrix as the View Type. Select Developer Requirement for the Requirement Type. Click Query to get the query builder window. Click Cancel in the initial window to focus on the query building process (see the figure in the next slide). Software Requirement Specification and Rational RequisitePro45

46 View queries: query row requirements window Software Requirement Specification and Rational RequisitePro46

47 View queries: selecting the requirement type and attribute to filter Add new criteria to the query by clicking Add and selecting the requirement type and attribute to filter. Make sure Developer Requirement is selected and then choose the Priority attribute from the list (see the figure bellow). Software Requirement Specification and Rational RequisitePro47

48 View queries (cont…) Specify the expected value. The Priority attribute has a fixed list of values, so you are provided with the list of these values: You can select All or None of these, or make multiple selections by clicking on each option as shown in the figure in the next slide. Make sure only High is selected. You can also select a sort order (only applicable if you are selecting multiple list values or working with a value attribute such as text, integer, or date). Software Requirement Specification and Rational RequisitePro48

49 View queries: list of values for the priority attribute Click OK. Software Requirement Specification and Rational RequisitePro49

50 Managing priorities, goals, and other attributes You can 'bulk' set attributes on a range of requirements by clicking the Set Attributes button in the toolbar. This sets the attribute value for the selected attribute column on all the requirements in a given view to a single value (see the figure bellow). Software Requirement Specification and Rational RequisitePro50
