  1. qatestingtips.com WHATIS PROCESS DEVELOPMENT?

  2. qatestingtips.com PROCESSDEVELOPMENT Process Development is to create activities for performing tasks. In other words, this is todesign stages of work, workflow sequence of software development complete cycle and create activities into phases with standardformat.

  3. Process DevelopmentDesign Process Development design is verychallenging task because activities will be followed according to process and if developed process is great then activities will be performed great else might be some mistakes over there with software system.

  4. SoftwareDevelopmentLifeCycle Software Development Life Cycle, SDLC for short, is a well-defined, structuredsequenceofstagesinsoftwareengineeringtodevelopthe intended software product. However, it also involves multiple steps suchasresearch,designingadataandprocessflow,writingtechnical documentation, comprehensively testing, debugging and pushing it iteratively tolive.

  7. Whatisthesoftwaredevelopment lifecycleandwhyisitsoimportant to haveone? Whether you plan it or not, every piece of software goes through a similar path from idea to launch day. Collectively,thestepsofthispatharecalledthesoftwaredevelopmentlifecycle(orSDLCforshort).TheSDLCis thesequenceofstepsthattakeplaceduringthedevelopmentofapieceofsoftware. Traditionally,eachstepcreatesanoutput–whetheranidea,document,diagram,orpieceofworking software–whichisthenusedastheinputforthenextstep.Andsoonuntilyouhityourgoal. Thatbeingsaid,softwareisneverreally“finished.”Eventhereleaseofyourfirstversioncanbeseenasjust anotherstepinthelifecycleofyoursoftware. The importance of having a clear process and knowing your development steps can’t be understated. Even though you can launch software without a clear process in place doesn’t mean you should. Thanks to years of testing,iteration,anddevelopment,modernsoftwaredevelopmentprocessesmakebuildingnewtoolscheaper, more efficient, and lessstressful.

  9. The7stagesoftheSDLC If you’re a project manager, you’re probably already familiar with the different steps in the SDLC. As the shepherd for a digital project, you have to think about everything from requirements to stakeholder communication,development,andongoingmaintenance.Thesestepsareallprettymuchthesameacross any software development process you use. However, as we’ll go into later, the order and sequence they occurin canchangedependingonyourneeds,goals, andprojectandteamsize(forexample,somesteps might be combined, duplicated, or run inparallel). 1.AnalysisandPlanning Onceacustomerorstakeholderhasrequestedaproject,thefirststepoftheSDLCisplanning. Thisusuallymeanslookinginto: Alignment: How does this project connect to your company’s larger mission and goals? Resourceavailabilityandallocation:Doyouhavethepeopleandtoolsyouneedtotakethison? Projectscheduling:Howdoesthisprojectfitwithinyourcompany’sgoalsandothertasks? Costestimation:Howmuchisitgoingtocost?

  10. The7stagesoftheSDLC 2.Requirements The next step is to understand the technical requirements of this project. Every piece of software— whetherit’sanapp,websiteredesign,ornewfeature—needstosolveacustomerproblem.Asyoumove onfromtheplanningphaseandcontinuetofillouttheSOW,askquestionsaboutthespecificsaround this project, suchas: Whatproblemdoesthissolve? Who’sgoingtouseitandwhy? Whatsortofdatainput/outputisneeded? WillyouneedtointegratewithothertoolsorAPIs? Howwillyouhandlesecurity/privacy?

  11. The7stagesoftheSDLC 3.DesignandPrototyping Withtherequirementsinplace,it’stimetostartdesigningwhatthissoftwarewilllooklikeandhowit willfunction.We’renottalkingaboutaestheticshere,butfunctionalityandflow.AsSteveJobsfamously said: Dependingonthesoftwaredevelopmentprocessyou’refollowing,thisphaseoftheSDLCmightmean youcreatesimplewireframestoshowhowinteractionswillworkinthesoftware,ormakemorefull- fledgedprototypesusingatoollikeMarvelorInVisiontotestwithusers.
