Which of the 7 phses is most important to HP?
All are equal.
-
What might happen if HP used the waterfall method to develop ERP?
The chance of success for the waterfall method is 10%, therefore failure would be likely
-
What are the 6 Primary Reasons for Failure?
- 1. Software problems affect the entire business
- 2. Unclear or missing requirements
- 3. Skip any phases
- 4. Project scope (layout) is bad
- 5. Failure to manage project plan
- 6. Changing Technology
-
As an Organization's reliance on software grows, so do the business-related consequences of software and failures including: (4)
- 1. Incr or decr in REVENUE
- 2. Repair or damage brand REPUTATION
- 3. Prevent or incur amount of LIABILITIES
- 4. Incr or decr PRODUCTIVITY
-
Define: Systems Development Life Cycle (SLDC)
the overall process for developing info systems from planning and alaysis through implementation and amintenance.
-
What are the first 4 steps of SLDC?
- 1. Planning
- 2. Analysis
- 3. Design
- 4. Development
-
Define: Business Requirement
detailed set of business requests that the system must meet in order to be successful
-
What are the last 3 steps of SLDC?
- 5. Testing
- 6. Implementation
- 7. Maintenance
-
T/F it is cheaper and easier to fix errors in SLDC process if it is done later in the process
False- it is more expensive and more difficult. It is better to take care of errors as early as possible.
-
Define: Waterfall Methodology
a sequential activity, based process in which each SLDC phse is performed sequentially from planning through maintenence (been here for 30 years, 10% success rate)
-
What are the 4 Challenges of Systems development?
- 1. Difficult and Risky
- 2. Many projects are never finished
- 3. Some projects finish 200-300% over budget
- 4. Some Projects finish on shedule and on budget, but do not meet their goals
-
What are the 5 promary reasons for failure for Systems Development?
- 1. Unclear or missing business requirements
- 2. Skipping SDLC phases
- 3. Failure to manage project scope
- 4. Failure to manage project plan
- 5. Changing technology
-
Define: Scope creep
occurs when SCOPE INCREASES
-
Define: Feature Creep
occurs when extra features are added
-
T/F- the later in the SDLC an error is found, the more expensive it is to fix
True
-
Define: Rapid Application Development (RAD)
emphsizes extensive user involvment in the rapid and evolutionary construction of working protoypes of a system to accelerate the systems development process
-
T/F- the Prototype is an essential part of the analysis phase when using RAD
True
-
Define: Prototype
a smaller scale representation or working model of the users requirements or a proposed design for an information system
-
T/F- The Prototype is essnetially the same as the actual SLDC process
True
-
SLDC- Investigation/ Analysis Stage
End users identify thier business needs and assess the feasibility of several alternative info system solutions
-
SLDC- Analysis/Design Stage
End users and or IS specialists use application development tools to interactively design and test prototypes of information system components that meet end user business needs.
-
Define: Project Management:
the application of knowledge, skills, tools, and techniques to project activities in order to meet or exceed stakeholder needs and expectations from a project
-
What are the 3 Interdependent variables or Project management?
- 1.Scope (increase scope, increase cost/time)
- 2.Time (decrease time, decrease scope)
- 3. Cost
-
What are the top 3 reasons why IT projects fall behind schedule or fail?
- 1. Poor planning or poor proj. management
- 2. Change in business goals during project
- 3. Lack of suppor from business management
-
Define: Project Plan
A formal, approved document that manages and controls the project execution
-
Preparing a project plan has to be prepared by: a team or an individual?
always a team
-
What is the 4 Criteria for a well defined project plan?
- 1. Easy to understand
- 2. Communicated to all key participants
- 3. Appropriate to the project's size, complexity and critiacality
- 4. Prepared by the team rather than the individual project manager
-
The Top 5 successful project management strategies
- 1. Define project success criteria
- 2. develop a solid project plan
- 3. Divide and conquer
- 4. Plan for change
- 5. Manage project risk
