Agile
•
This methodology is ideally suited for medium- and long-term projects where
user requirements can change and outputs are required at timed intervals.
•
Understand what is involved in each phase of the methodology, including:
o
iteration 1 phase – where potential projects are analysed before being selected
for development, funding provided, and roadmaps produced
for technology
and the business
o
iteration 0 phase – where the initial modelling, planning and organisation takes
place, e.g. prototypes of the products are created and initial requirements and a
release plan are defined
o
construction iterations phase – a series of time-constrained iterations consisting
of prioritised work items in a ‘sprint’ where a product is produced, daily
meetings to discuss team progress and end of iteration reviews to demo to
stakeholders
o
transition and release phase – where the product is released into production as
a working system
o
production phase – where the product is delivered to the customer, including
the phases of support
and maintenance
o
retirement phase – where the product is removed from development.
•
Benefits, to include flexibility in constantly changing applications, clear visible
outputs during each iteration of development and appropriate planning of
resources ensures first to the market and continual releases.
•
Limitations, to include teamwork from all stakeholders required to ensure the
process is successful, full commitment and effort is required in projects and the
need for experienced development teams to make decisions during the project.
