This flexibility is especially helpful if your team has a eed it must address immediately. oe set of tools that are tested ad updated together i each Suite release. 14 Itroducig Ratioal Suite

Icorporate Best Practices ito Your Team s Process Oe of the first steps whe solvig commo developmet problems is to evaluate your team s software developmet process. Ratioal advocates followig a set of software-egieerig practices based o its ow experiece as well as the experiece of its may customers. All Ratioal Suite editios are desiged to support these six best practices: Develop software iteratively. Iterative developmet meas developig the software i plaed icremets. The project team plas, develops, ad tests oe subset of system fuctioality per iteratio. The team develops the ext icremet, itegrates it with the first iteratio, ad so o. Each iteratio results i either a iteral or exteral release. I the project lifecycle, there are multiple iteratios. Each iteratio focuses o oe of these developmet phases: Iceptio Defie scope of project. Elaboratio Pla project, specify features, baselie architecture. Costructio Build ad test product. Trasitio Trasitio product ito ed-user commuity. Welcome to Ratioal Suite 15

The followig diagram represets the full developmet lifecycle. Notice the multiple iteratios withi each phase. The height of each workflow shows whe the work becomes more itese for each phase i the project. The followig diagram illustrates the steps i a iterative process: Requiremets Aalysis, Desig, Codig, ad Uit Testig, ad Subsystem ad System Testig. Iteratio 1 Iteratio 2 Iteratio 3... Requiremets Aalysis Requiremets Aalysis Requiremets Aalysis Desig Desig Desig Codig, Uit Testig Codig, Uit Testig Codig, Uit Testig Subsystem ad System Test Subsystem ad System Test Subsystem ad System Test 16 Itroducig Ratioal Suite

These steps correlate with the resposibilities of specific team roles: aalyst, architect ad developer, ad tester. Although these activities are preseted as liear steps, each role performs these activities as early as possible ad throughout each iteratio. Requiremets aalysis, for example, is emphasized at the start of a iteratio; however, the aalyst tracks requiremets throughout the iteratio ad throughout the project lifecycle. Maage requiremets. Requiremets defie what the customer ad other stakeholders eed. Other sources of requiremets are your orgaizatio s competitive eviromet, legal costraits, ad performace criteria. Requiremets chage throughout the project. Maagig requiremets ivolves evaluatig these chages ad determiig their impact. Use compoet-based architectures. A compoet is a o-trivial, early idepedet, part of a system that combies data ad fuctios to fulfill a clear purpose. You ca build compoets from scratch, re-use compoets you have previously built, or eve purchase compoets from other compaies. These compoets form the architecture the fudametal framework for your software project. Visually model software. Visual models improve your team s ability to maage software complexity. Creatig a graphical blueprit of the system's architecture coveys complex iformatio i a commo laguage that all members ca uderstad. A visual model helps team members detect icosistecies ad mistakes i the product architecture. From a model, you ca quickly uderstad the impact of chages over the course of a project. Verify software quality. Verifyig quality meas testig how well the project meets its requiremets. It also meas testig reliability ad performace. With iterative developmet, you ca start testig early. This early testig eables you to discover ad resolve problems as early as possible i the developmet cycle. Cotrol chages to software. It is importat to maage chages i a trackable, repeatable, predictable maer. Ehacemet requests ad defect reports help facilitate clear commuicatio amog team members. Your team should also defie repeatable processes for chagig requiremets ad code. Welcome to Ratioal Suite 17

Adoptig these Practices Ratioal has developed the Ratioal Uified Process, a Web-eabled, searchable kowledge base that helps you aalyze your ow developmet practices ad helps you icorporate these software egieerig practices ito your developmet pla. The Ratioal Uified Process is a team-uifyig tool. It is icluded i every Ratioal Suite editio. The Ratioal Uified Process provides the followig liks betwee process guidelies ad the tools cotaied i Ratioal Suite: Tool Metors provide step-by-step istructios for performig Process activities usig Ratioal tools. Exteded Help is available i Ratioal tools ad provides pathways to parts of the Process, icludig Tool Metors. You ca add your ow cotet to Exteded Help to tailor it to your team s work. 18 Itroducig Ratioal Suite

Customizig the Ratioal Uified Process The Ratioal Uified Process is ot a static resource. You ca easily customize the Process by addig iformatio from your project, such as guidelies ad stadards. Moreover, you do ot have to take a all-or-othig approach to the Ratioal Uified Process. You ca start by usig a subset of the Process, perhaps to address a area that presets difficulties to your team. Whe you are ready to tackle aother area of difficulty, you ca icorporate aother part of Ratioal Uified Process ito your developmet practices. What s Next? The remaider of this book: Illustrates how the aalyst, developer ad architect, tester, ad project leader beefit by usig the Ratioal Suite. Shows how the tools fit ito a effective iterative process by focusig o requiremets maagemet, desig, codig ad uit testig, ad subsystem ad system testig.

Are your users dissatisfied with your product? Bridgig the Gap betwee the Customer ad Your Team As the aalyst, you iterpret requests from stakeholders ad determie what the system will do. You represet the customer by collectig, maagig, ad commuicatig requiremets to the rest of the developmet team. It is essetial that all stakeholders clearly uderstad the system s objectives ad requiremets eve as these objectives ad requiremets chage durig the project. Requiremets Aalysis: The First Step i Iterative Developmet I iterative developmet, your project team plas, develops, ad tests oe subset of system fuctioality. Each iteratio results i either a iteral or exteral release. I the ext iteratio, your team develops the ext icremet of fuctioality, itegrates it with the first release, ad the cycle cotiues. At the start of a iteratio, you prioritize, schedule, ad assig resposibilities for requiremets. Throughout the iteratio, you track these requiremets ad evaluate how well the team has met them. 21

Iteratio... Requiremets Aalysis Desig Codig, Uit Testig Subsystem ad System Test Durig developmet, requiremets ca chage ad evolve. For example: Your competitors have released ew or updated versios of their products. To stay competitive, you add requiremets for ew features to your project. The customer was uclear or udecided about some requiremets at first, so you might add, remove, or clarify requiremets later o. Techology advaces after you start product developmet. You eed to determie if you ca icorporate these ew features ito your project without jeopardizig the schedule or other deliverables. You discover that a requiremet is too expesive to implemet or that your team caot implemet it i the time allotted, ad you decide to drop the requiremet. Maagig Requiremets with Ratioal Suite AalystStudio Ratioal Suite AalystStudio is the complete solutio for developmet professioals who gather ad maage project requiremets. This Ratioal Suite editio icreases customer satisfactio by helpig your team build a system that meets your customers eeds. 22 Itroducig Ratioal Suite

Defiig Requiremets for Your Team Ratioal RequisitePro ehaces team commuicatio by helpig the aalyst articulate ad maage requiremets i a form accessible to all stakeholders. It combies the familiar ad flexible eviromet of Microsoft Word with the power of a relatioal database. You, as the aalyst, ca use Microsoft Word to documet project requiremets. You the store ad track this iformatio i the RequisitePro database. The database allows you to specify requiremet attributes, ad to sort, filter, ad relate requiremets to other requiremets. RequisitePro s comprehesive features eable you to quickly assess the impact of ay chages o requiremets. Because every team member eeds the same uderstadig of project goals ad objectives, you have to keep your team up to date o requiremets activities. RequisitePro makes this easy by providig RequisiteWeb. This Web capability eables UNIX users ad other team members who do ot have RequisitePro o their desktops to review ad update requiremets. Trackig Requests for Your Project Ratioal ClearQuest ecourages collaboratio by trackig ew feature, ehacemet, or chage requests from team members ad other stakeholders. The ClearQuest Web iterface esures that UNIX users ad other team members who do ot have ClearQuest o their desktops ca participate i this collaboratio. Your team ad other stakeholders ca evaluate requests, determie their impact o the system, ad whe applicable, validate the chages. To establish how chage request fit ito the structure of features ad mai requiremets, you ca lik requests to a existig or ew project requiremet i Ratioal RequisitePro. Chapters 3 ad 4 discuss ClearQuest s defect trackig features. Buildig a Bridge: The Aalyst 23

SoDA ca work with oe Ratioal tool, such as RequisitePro, or combie iformatio from more tha oe tool, such as Ratioal RequisitePro ad ClearQuest. These reports provide a way for your team to commuicate more efficietly ad cosistetly. SoDA s reportig features provide templates i either Microsoft Word for Widows or Adobe FrameMaker o UNIX. You ca easily customize these templates or create ew oes. Optimizig Your Work with the Ratioal Sychroizer The Ratioal Sychroizer automatically creates items i your project based o the existece ad status of related items. This tool helps your team maage project elemets by esurig that all related items exist at the right time, ad that oe of them are lost. For istace, i Ratioal Suite AalystStudio, oce you've captured feature ad use case requiremets i the RequisitePro database, you ca use the Sychroizer to geerate test requiremets. You ca also use the Sychroizer to geerate a sequece diagram i Rose. Summary Ratioal Suite AalystStudio provides a itegrated set of tools to help you effectively maage ad commuicate requiremets to your project group. Ratioal RequisitePro, the primary tool i AalystStudio, helps you iterpret requests from stakeholders ad determie what the system will do.

INTRODUCING RATIONAL SUITE Maagig Complexity: The Developer Maagig a Complex Process Ca you build the system right the first time? Do you discover desig flaws too late to fix them? Do project modules itegrate properly? Ca you maitai the itegrity of the system s architecture? Ca you easily exted the system s desig? Ca you reuse project compoets? Architects ad developers defie how the system works. I the architect role, you desig the system architecture. You must desig a flexible system that ca be modified as customer eeds chage. As the developer, you create, modify, ad maage code for the system o the basis of this model. Desig, Codig, Uit Testig: The Next Steps i Iterative Developmet As the architect, you review project requiremets ad the make decisios about the structural elemets ad iterfaces of the system. As requiremets chage ad ew problems arise i each iteratio, you must refie the system architecture. I the system desig, you lay out the compoets of the architecture. These idividual compoets are idepedet, replaceable parts of the system that have clearly-defied fuctios ad iterfaces. Whe you work with compoet-based architectures, your project team ca create ew compoets or reuse, ad eve customize, existig compoets from previous projects or commercially available sources. 27

Iteratio... Requiremets Aalysis Desig Codig, Uit Testig Subsystem ad System Test As the developer, you produce executable code that ca be evaluated agaist the project requiremets durig each iteratio. As a resposible developer, you test your code before you release it to other developers or to your testig group. This approach allows you to discover ad respod to problems early eough to miimize their impact o the project. Creatig Compoet-Based Architectures with Ratioal Suite DevelopmetStudio (Widows ad UNIX) Ratioal Suite DevelopmetStudio is the complete solutio for software architects, desigers, ad developers. This Suite helps your team desig ad build the project right the first time. Ratioal Suite DevelopmetStudio RealTime Editio is further tailored for practitioers who focus o real-time ad embedded developmet.

Commuicatig Visually Ratioal Rose (Eterprise Editio) helps you visualize, specify, costruct, ad documet the structure ad behavior of your system s architecture. With Rose, you ca provide a visual overview of the system usig the Uified Modelig Laguage (UML), the idustry-stadard laguage for visualizig ad documetig software systems. Rose uifies the team by helpig you create models that all team members ca share, test, ad revise. It esures that all members have the same uderstadig of the project. Durig desig ad code reviews, team members use project models to see the ramificatios of ay chages they wat to make to the code. Logical View of Architecture i Rose Maagig Complexity: The Developer 29

Jump-Startig Code Implemetatio You ca jump-start the codig process by geeratig code frameworks from the models developed i Ratioal Rose. This process is called forward egieerig. Rose supports may laguages, icludig Microsoft Visual Basic, Visual C++, Visual Java++, IBM Visual Age for Java, HP Workbech, ad Su Workshop. Note: The Ratioal Rose Modeler Editio i AalystStudio does ot geerate code, update code, or update models. Keepig Code ad Models Cosistet Oce you chage code, you ca direct Rose to update the model, esurig that your model ad code remai cosistet throughout the project. This process is called reverse egieerig. Revisig your visual models helps you see the impact of chages o the architecture. It is importat to assess these chages because they may violate project stadards or architectural decisios. If they do, they eed to be reworked. If they do ot, they must be reflected i the software architecture ad commuicated to the etire project team. Evaluatig Requiremets Visually Ratioal RequisitePro provides up-to-date requiremets data i a form accessible to all stakeholders. This access is provided with RequisiteWeb, a Web iterface that eables all stakeholders to review ad update requiremets. Whe you, the architect, see additios or chages to requiremets i RequisitePro, you ca icorporate these chages ito the project Rose models. As you chage these models, you gai a uderstadig of the impact these chages have o the system. 30 Itroducig Ratioal Suite

Validatig Chages to the System Ratioal ClearQuest tracks ew feature, ehacemet, or chage requests from team members ad other stakeholders i a form accessible to everyoe. The ClearQuest Web iterface esures that UNIX users ad other team members who do ot have ClearQuest o their desktops ca review ideas ad feedback. Usig Rose models, you ca determie the impact of these requests o the system, ad the if applicable, validate the chages. Keepig the Team Up to Date Ratioal SoDA (for Microsoft Word or for Adobe FrameMaker) allows you to geerate up-to-date project reports for the etire team by extractig data from oe or more tools. SoDA ca work with oe Ratioal tool or combie iformatio from more tha oe tool. Its reportig features provide templates i either Microsoft Word o Widows, or Adobe FrameMaker o UNIX. You ca easily customize these templates or create ew oes. Testig Code Early ad Ofte As a developer, you perform code testig while you implemet code. Ratioal Suite provides testig tools to use as soo as you have a workig program. Ratioal Purify checks every active C++ compoet i your program for ru-time errors ad memory leaks, the most difficult errors to fid. They are the most importat to correct, though, because they ofte remai udetected util triggered by some radom evet. A program ca seem to work correctly for a log time before these types of errors are discovered. Ratioal PureCoverage checks every compoet i your program for lies of code that the program fails to exercise. Ratioal Quatify detects performace bottleecks, which are places where the code is ruig iefficietly. It pipoits where the applicatio is spedig its time, ad why a specific fuctio is particularly slow. Quatify helps you improve system performace so that you ca deliver efficiet software. Maagig Complexity: The Developer 31
