Runninga project

• Methodology–Waterfall– Agile=>seeitasatoolbox,pick&choose,andmuchofitiscommonsense

• Progresstracking– Createsclarity– Allowsdecisions

Waterfall

Waterfall• Traditionally,ITprojectswerebasedonanengineeringapproach– Largecostofchange– Abilitytospecifyoutcome– Languageforspecification

• Everythingdesignedanddefinedatthebeginningoftheproject

WhyAgileforresearch?

• Earlyvalidation• Lotsofadjustment

• MVPapproach• Smallteams

ADailyStand-updoesnotanAgileProjectmake

AgileSoftwareDevelopment

• Backlogofsmallpieces(features)– decomposition

• Prioritization(“grooming”)• DeliverandDemo• Reviewandadjust– nextiteration• Done• RinseandRepeat– Danger:don’tkeepreworkingthefirstbitandnevergettotheendbit

Scrum

• Prioritizedbacklog– Features– Acceptancecriteria

• Fixedtime(typically2weeks)– “Sprint”• DefinitionofDone• Teamcommitstoselectingdoableprioritiesandgettingthemtodone

• Somethingalmostdoneisnotdoneandmovestothenextsprint

Sprint

Othertypicalaspectsofagile• Collaboration– selforganizedteams• Colocation• Frequentquickgroupmeets(dailystand-ups,5-10mins)

• Roles– Productmanager->productfocus– Team(dev&test)->deliveryfocus– Scrummaster->processfocus

• Crossfunctional• Plan&retrospective– continuousimprovement

Kanban

• Workmanagementapproach• Workispulledwhencapacitybecomesavailable

• Fromprioritizedlist(“backlog”)• Progress(nextbit)shownonkanban board

Progresstracking

• Helpscommunicationintheteam• Usesscheduleandbudgetresponsibly• Allowsforadjustment• GreatforPR
