ProjectManagement• WaterfallMethod– Moretraditionalstyleofprojectmanagement.Asequentialdesignprocessinwhichprogressisseenasaflowing,steadilydownwards(likeawaterfall)throughthephasesofConception,Initiation,Analysis,Design,Construction,Testing,Production/Implementation,andMaintenance.

• AgileMethod– Agroupofsoftwaredevelopmentmethodsbasedoniterativeandincrementaldevelopment,whererequirementsandsolutionsevolvethroughcollaborationbetweenself-organizing,cross-functionalteams.

WaterfallMethod

WaterfallMethod• Pros

– Longerdesignandplanningstageallowsformorepotentialforeseeablebugavoidance.

– Emphasisondocumentationreducesmiscommunicationandemphasizesaccountability.

– Designpassesthrougheasilyunderstandableandexplainablephases.

• Cons– Impossibletopredicteveryminuteproblemduringpre-

production.– Clientsmaynotknowexactlywhattheywantthefinal

productorfeaturelisttobeuntiltheyseeaworkingprototype.

– Designmustadapttothetechnology.

AgileMethod• Pros

– Workingsoftwaretopresenttoclientsearlierinproduction– Clientscanvisualizefinalproductmorequickly(andmakechanges

asnecessary).– Short“time-boxes”keepfocusontheshorttermgoals.– Minimalbugsattheendofeachiteration.

• Cons– Canbeinefficientinlargeorganizationsorverylargeprojects.– Clientresistancetonon-traditionalmethod(hardertotrack

milestones).– Hardertoadapttooffsiteoroffshoreteammembers.

Agileterms• SCRUMMaster- Thepersonaccountableforremovingimpedimentsto

theabilityoftheteamtodeliversprintgoals/deliverables.• ProjectOwner- Primaryauthoroftheuserstories,ownstheproduct

backlog,prioritizesthestories,writesacceptancetestsandacceptsworkcompletedbytheteam.

• Backlog- Anever-evolvinglistofproductrequirements,prioritizedbythecustomer(orcustomerrepresentative),thatconveystoanagileteamwhichfeaturestoimplementfirst.

• Sprint- TheuninterruptedperiodoftimeduringwhichanAgiledevelopmentteamperformswork,mostcommonly1-4weeksinlength,atwhich,theteamdeliversa“potentiallyshippable”product.

• Stand-Up-Ashort,daily,all-handsmeetinginwhichmembersofanAgileteamaddressthreequestions:– Whatdidyougetdonesincethelaststand-up?– Whatwillyoudobeforethenextstand-up?– Whatimpediments standinyourway?

MilestoneTerminology

• Prototype- Anearlysampleorreleaseofaproductbuilttotestaconceptorprocess.

• Build- Acompiledversionofaprogram.• Pre-Alpha- Allactivitiesperformedduringthesoftwareprojectbeforetesting.SomecontractswillrefertothelastmilestonebeforeAlphaas“Pre-Alpha”.

• Alpha- Releasestageinwhichallessentialfeaturesareplannedandwillbeaddedinthenearfuture.Nonewfeatures/contentcanbeaddedtothedesignatthispoint.

MilestoneTerminology

• Beta- Releasestageinwhichallfeaturesarecompleteandwherebugfixingismostimportant.

• ReleaseCandidate(RC)- Abetaversionwithpotentialtobeafinalproduct,whichisreadyunlesssignificantbugsemerge.

• GoldMasterCandidate(GMC)- Alsoreferredtoas“Releasetomanufacturing”orRTM.Asoftwareproductthatisreadytobedeliveredorprovidedtothecustomer.

Prototyping

• WhyPrototype?– Fast– Cheap– Easy– Workoutmajorproblems– Getteamonthesamepage– Workoutbugs– Motivate!
