Study Notes

Bruges til at reducere usikkerhed og gradvist nærme sig en tilfredsstillende løsning
Virkelige problemer er sjældent klare og præcise
Planlægning er usikkert, og prøv og fejl reducerer usikkerhed
Evolution anerkender og understreger usikkerheder
Problemet bliver fortolket og revideret (Iterationer)
Resultatet er en tilfredsstillende version af systemet
Systemet bliver eventuelt videreudviklet (inkrementer)

Fleksibilitet, Brugerinvolvering, Risiko-reduktion (via iterationer hjælper med at identificere og løse problemer tidligt)
Ulemper: Potientiel ineffektivitet, uklar slutstatus, højere omkostninger

Karakteriseret ved en sekventiel og linære tilgang
Fokuserer på iterative og inkrementelle processer, der involverer kontinuerlig feedback og tilpasning
Flexible, Responsive Software Delivery
Little formal, up-front planning
Flexible Scope: Initial Product Backlog
User Stories, Prioritized
Implementation: Combining emergent requirements during iterative (sprint-based) construction
Advantages: Highly adaptability to changes and new requirements, Continuous feedback and involvement from stakeholder, Incremental deliver of working software allows for early and frequent value realization
Disadvantages: Less predictability in terms of overall project scope, timeline and cost, Requires high levels of collaboration and communication, Potential for scope creep if not managed properly

Kombinerer elementer fra både plan-driven og agile metoder
Fordele: Giver mulighed for både forudsigelighed og fleksibilitet, Kan tilpasses forskellige dele af projektet baseret på deres specifikke behov og risici, Både håndtering af komplekse projekter med forskellige krav og usikkerheder
Ulemper: Kan være kompleks at administrere, da det kræver en balance mellem forskellige metoder, Risiko for konflikt mellem plan-dreven og agile dele af projektet, Kræver omhyggelig koordinering og styring for at sikre at de forskellige dele fungerer godt sammen

Agile: Fleksibel og responsiv overfor ændringer, Little upfront planning, Flexible scope, Iterative construction
Plan-driven: Highly predictable Software Delivery, Heavy up-front planning, Fixed scope, Single phase, long-duration construction
Agile advantages: Highly adaptable to changes, Continuous feedback and involvement, Incremental delivery of working software
Agile disadvantages: Inflexibility to changes, High risk if initial requirements and design are flawed, Potential for wasted effort
Plan-driven advantages: Predictability in terms of cost, timeline and deliverables, Clear documentation and structured process, Easier to manage large teams and complex projects
Plan-driven disadvantages: Inflexibility to changes, High risk if initial requirements and design are flawed, Potential for wasted effort
