and Correct Answers| Latest Update 2024/2025
What is timeboxing - ANSWER A technique for ensuring the most critical
requirements of the software are deployed in a timely manner, with enhancements
coming later if needed.
Timeboxing - a fixed deadline for a project and delivers the system by that deadline
no matter what, even if functionality needs to be reduced.
How many gathering strategies are there? - ANSWER 8 gathering strategies
(Problem analysis, Root cause analysis, duration analysis, activity-based analysis,
informal benchmarking, outcome analysis, technology analysis, activity elmination
One of the outcomes of using a use case is: - ANSWER describe all the tasks that
users need to perform using the system & giving out instructions in case of
emergency happens outside or the normal course of the system
How many steps does Planning phase have? and what are they? - ANSWER The planning
phase has 2 steps:
1) Project initiation
-system's business value is identified
-system request
-feasibility analysis (can we build it?)(will it provide value?)(if we build it will w=it
be used?)
- enters the approval committee to determine the feasibility
2) after approval it enters project management
,- project manager creates a work
plan -staffs project
-set techniques to help
control -project work plan
* how the project team will go about developing system
How to distinguish level 0 and level 1 diagram? - ANSWER Each level will have 1 extra
decimal. For example, level zero will be 1, level 1 will be 1.1, or level 2 will be 1.1.1, and
so on. In addition, level-one diagrams show the internal processes that comprise a
single process on the level-0 diagram.
Elements of a systems request - ANSWER - Project Sponsor is the person who initiates
the project and who serves as the primary point of contact for the project on the
business side.
- Business need is the business-related reason for initiating the system.
- Business requirements are the new or enhanced business capabilities that the
system will provide.
- Business value is the benefits that the system will create for the organization.
- Special issues or constraints are the issues that pertain to the approval committee's
decision.Fsys
Criteria to consider when selecting a development methodology: - ANSWER Whether
the system has unclear user requirements, has a short time schedule, and is complex
Microsoft named their project management system as? - ANSWER Microsoft Project
which is common in the industry
Manage risks: - ANSWER Ways to manage risks are avoidance, reduction(mitigation),
transfer(insure or share), and retention(accept).
,Two team strategies - ANSWER Working synchronously
Divide and conquer
Is it critically important to reassess feasibility throughout the project? - ANSWER Yes!
We will be working with "living documents" which require change over time. When
new information comes forward, we must reassess and update our information.
Why is it so common for large system development projects to fail? - ANSWER There
may be Missed Deadlines, Scope Creep, Poor Planning, etc.
It all comes down to whether the project was correctly and carefully planned and
whether the organization stuck to the plan.
What are the main categories that should be listed in the Cost-Benefit Analysis? -
ANSWER Benefits, Development Costs, & Operational Costs
How DFDs are organized into levels (Context, Level 0, Level 1, etc.) and how to
number the processes in each level - ANSWER Context Diagram - is always "Process 0"
-Top-level DFD in every process model
-Shows the context into which the business process fits
-Shows the overall business process as just one process (process 'zero')
-Shows all the external entities that receive information from or contribute
information to the system
-No data stores
Level 0 Diagram - are always numbered with integer values (1, 2, 3, etc.)
-Shows all the major processes that comprise the overall system - the
internal components of process 0
, -Shows how the major processes are interrelated by data flows
-Shows external entities and the major processes with which they interact
-Adds stored data via the data stores
Level 1 Diagrams - always have one "dot": parent number "dot" unique number (1.1,
1.2, 1.3, etc.)
-Create one level 1 diagram for every major process on the level 0 diagram
-Shows the internal processes that comprise a single process on the level 0 diagram
-Shows how information moves to and from each of these processes
Names, goals, and general strengths and weaknesses of Waterfall Development -
ANSWER -Based upon SDLC; assumes a project phase is complete before moving to
the next phase. You could go back to the prior phases if you need to make
modifications/refinements. Most traditional method available.
-Goal: Doing each phase thoroughly before moving forward ensures correct and high-
quality outcomes.
-Strengths:
+System requirement identified long before construction begins
+Requirements are "frozen" as project proceeds - no moving targets allowed
-Weaknesses:
+Must wait a long time before there is "visible" evidence of the new system.
+Takes a long time from start to finish.
What is the difference between temporal and external triggers? - ANSWER Temporal
trigger- is a time-based trigger that occurs based on a time frame, rather than an
external event. An example might be sending an email about special offers once a week
on Tuesday morning or paying a monthly bill
