ISDS 406; Midterm 1; Ch. 2 (PlanningPhase)
Agile development - correct answer ✔Agile development7 is a group of
programming-centric methodologies that focus on streamlining the SDLC.
Much of the modeling and documentation overhead is eliminated; instead,
face-to-face communication is preferred. A project emphasizes simple,
iterative application development in which every iteration is a complete
software project, including planning, requirements analysis, design, coding,
testing, and documentation (Figure 2-8). Cycles are kept short (1-4 weeks),
and the development team focuses on adapting to the current business
environment. There are several popular approaches to agile development,
including extreme programming (XP)8, Scrum9, and dynamic systems
development method (DSDM).
CASE repository - correct answer ✔The central component of any CASE tool
is the CASE repository, otherwise known as the information repository or data
dictionary. The CASE repository stores the diagrams and other project
information, such as screen and report designs, and it keeps track of how the
diagrams fit together....As the project evolves, project team members perform
their tasks by using CASE and have access to each project team member's
additions to the CASE repository.
Chief information officer (CIO) - correct answer ✔Oversees all uses of IT and
ensures the strategic alignment of IT with business goals and objectives
Computer-aided software engineering (CASE) - correct answer ✔CASE is a
category of software that automates all or part of the development process.
Some CASE software packages are primarily used during the analysis phase
to create integrated diagrams of the system and to store information regarding
the system components (often called upper CASE), whereas others are
design-phase tools that create the diagrams and then generate code for
database tables and system functionality (often called lower CASE).
Integrated CASE, or I-CASE, contains functionality found in both upper-CASE
, and lower-CASE tools in that it supports tasks that happen throughout the
SDLC. CASE comes in a wide assortment of flavors in terms of complexity
and functionality, and there are many good programs available in the
marketplace, such as Visible Analyst, Oracle Designer, Rational Rose, and
the Logic Works suite.
Design prototype - correct answer ✔A design prototype is not intended to be
a working system. It contains only enough detail to enable users to
understand the issues under consideration.
Documentation - correct answer ✔A technique that project teams put in
place during the planning phase is good documentation, which includes
detailed information about the tasks of the SDLC. Often, the documentation is
stored on a file server available to the entire team—a sort of electronic project
binder. Stored in this location are all deliverables and all internal team notes
and communication—the history of the project.
Estimation - correct answer ✔Estimation is the process of assigning
projected values for time and effort.
Feature Creep - correct answer ✔As systems are developed more quickly
and users gain a better understanding of information technology, user
expectations may dramatically increase and system requirements may
expand during the project (sometimes known as scope creep or feature
creep).
Functional Lead - correct answer ✔A functional lead usually is assigned to
manage a group of analysts
Group Cohesiveness - correct answer ✔Group cohesiveness (the attraction
that members feel to the group and to other members) contributes more to
productivity than do project members' individual capabilities or experiences.
