Key dimensions of system
development are support analysis, design, development and deployment. Each of
these involves planning and
testing. The lifecycle provides a roadmap and resources into the steps to
initiate, plan,
execute, control and close or reevaluate
systems. For example, in documentation of initiating authority to
coordinate a team to conduct a
feasibility study into various technologies or establishing terms or reference
to set
up documents for collaboration.
All this planning is given detail on how things are done or accomplished with
regards on matters into resources,
quality standards, financial, metrics/statistic, planning, risk assessment and
procurement. The understanding of
what works and does not work on which existing systems are already in place
warrants or elicts analysis that
gives the perspective to adjust the problem by various sources of data
collection
methods. Designing is the time and
scope of options available and getting feedback development in the actual
building portion that is useful
for client or business solutions. Prior to deployment and implementation,
testing is
critical to the adoption and
scalability of users and work processes. Each phase provides a feed of detailed
information into the next critical step of system
development and is essential to the structure of project completion.
Complexity of the task is defined by
both organization and technology. The typical component list
involves the existing systems,
infrastructure, new technology, user units, stakeholders, the project
team, vendors, and external service
providers. As the number of SD components increases the
difficulty in monitoring, measuring and
controlling the task increases as well. The complexity of any
SD will also be affected by software,
hardware and perhaps the greatrest influence or complexity is
the human component.
