Waterfall sotware development process: tradiional approach to sotware development, linear progression, requirements up front, saves development costs , soluion built to speciicaions. Major components in the bi life cycle: source systems & etl. Less immediate value-add to biz: dashboard, reports, alerts. Elements requiring change in bi archeritecture: provide periodic release schedule, balance stability & responsiveness, change frequency varies by . Promote flexibility: balance stability & responsiveness, change frequency varies by . A subset of principles from the agile manifesto: our highest priority is to saisfy the customer through early and coninuous delivery of valuable sotware, welcome changing requirements, even late in development. Agile development techniques project plan: agile manifesto" welcomes changes. Opposite of waterfall: broad requirements, prototyping used to reine capabiliies, mock ups built in excel, iteraive process, weeks vs. A development ime, usually a month, in which a set of product capabiliies is delivered. A release cycle may be composed of muliple sprints: product backlog.
