,Insourcing - Answer -assigns a project to employees within the organization. Insourcing
generally requires the development of new operations and processes, making it an
expensive option.
The project management life cycle is represented differently in various models, but
projects generally include four phases: - Answer -initiation, planning, execution, and
closure.
Project initiation - Answer -broadly defines the project. It usually begins with a business
case, followed by a feasibility study. During the feasibility study, research assesses
whether the business case will lead to a reasonable, feasible solution. Project
stakeholders provide input in the analysis of the business case, resulting in a project
charter, or project initiation document, that outlines the business needs, the
stakeholders, and the business case.
Project planning (1 of 2) - Answer -includes developing a road map that everyone
follows. This phase starts with setting the project goals, commonly using the SMART or
CLEAR frameworks, both of which are described below.
Specific: Set a specific goal that answers the questions who, what, where, when, which,
and why.
Measurable: Create criteria that can be used to measure the success of the goal.
Attainable: Ensure the goal is attainable given the resources.
Realistic: Assess the willingness to work toward the goal.
Timely: The goal should be achievable within the available timeframe.
Collaborative: The goal should encourage employees to work together.
Limited: The goal should be limited in scope and time to keep it manageable.
Emotional: The goal should tap into the passion of employees and be something they
can form an emotional connection to. This can optimize the quality of work.
Appreciable: Break larger goals into smaller tasks that can be quickly achieved.
Refinable: As new situations arise, be flexible and refine the goal as needed.
Project planning (2 of 2) - Answer -defines the project scope and drafts a project
management plan. The project management plan identifies project resources, including
cost and time estimations. A project generally has each of the following documents by
the end of the planning phase:
scope statement outlining the objectives, deliverables, and milestones
work breakdown structure (WBS) breaking the project into manageable segments for
the team
milestones defining high-level goals to meet throughout the project's duration
communication plan outlining the frequency and methods of communicating with
stakeholders
,risk management plan identifying foreseeable risks, including cost overruns and delays
Project Execution - Answer -During project execution, project deliverables are
developed and completed. A kickoff meeting usually marks the start of this phase.
Tasks typically include developing the project team, assigning resources, setting up
tracking systems, conducting status meetings, and monitoring the project timetable.
Project performance is constantly observed during the execution phase. Key
performance indicators, or metrics, are used to monitor the progress of the project,
determining whether the project is on track to meet the defined milestones.
Project Closure - Answer -At the project closure phase, the project is declared complete
and the project team is dissolved. Project managers complete the final project
documentation, including financial reports. Generally, meetings are also a part of this
phase, allowing members of the project team to reflect on strengths and opportunities
for improvement.
Risks in execution - Answer -typically revolve around budget, people, technology,
equipment, and stakeholder support. Issues that can deem a project unsuccessful
include cost overrun, insufficient staff, inadequate tools to support the project, and lack
of support from project stakeholders. Planning in advance is one of the best ways to
mitigate risks of execution.
Risks of integration - Answer -The outcome of a project will likely affect other systems
and processes in an organization. Risks of integration can be mitigated by assessing
potential disruptions, ensuring adequate support from stakeholders, and having a
shared understanding of the project's complexity.
Two key strategies to successfully identify risks are frequent monitoring of project
parameters and milestones and sound communication between project participants.
Scope creep - Answer -uncontrolled change of a project's scope, typically adding tasks
and increased, unplanned costs to the project
Budget risk - Answer -budget control issues, such as underestimated or improper
allocation of cost
Resistance to change - Answer -departments and individuals resist organizational
changes resulting from the project
Resource risk - Answer -inability to secure sufficient resources for the project
ex.
Mei is concerned that some team members may become unavailable during the project.
, Contract risk - Answer -a vendor fails to deliver on contractual obligations
Disputes risk - Answer -Disputes or disagreements between project participants
Project dependencies - Answer -especially when completion of some tasks is
dependent on the completion of other tasks
Project assumptions risk - Answer -when assumptions about the project are invalidated
during project development
Benefit shortfall - Answer -the project meets the requirements but delivers fewer
benefits than outlined in the business case
Requirements quality risk - Answer -requirements have not been properly validated or
documented
Force majeure risk - Answer -the chance of a major negative event beyond human
control, such as a natural disaster
Software Development Life Cycle - Answer -Planning,
Design,
Implementation,
Testing,
Deployment,
Maintenance
System Development Life Cycle - Answer -Requirement Analysis,
Design,
Implementation,
Testing
The goal of the requirements analysis is - Answer -to determine what services the
system will provide, identify any conditions (such as time constraints and security), and
define how users will interact with the system.
Requirements analysis requires - Answer -significant input from stakeholders, such as
potential users, as well as those with other ties, such as legal or financial interests. In
cases where the beneficiary is an entity, like a company or government agency,
requirements analysis may start with a feasibility study. The feasibility study determines
whether development is possible under the given constraints and whether the
development aligns with the organization's mission. In the case of producing
commercial off-the-shelf (COTS) systems for the mass market, requirements analysis is
likely to begin with a market study by the system developer.
The requirements analysis process consists of three steps: - Answer -1). Compiling and
analyzing the needs of the system use
