Question

Based on System acquisition process from the software development life cycle through contract negotations. What approaches might be used to select a system?

Regardless of the approach which stakeholders need to be involved in the requirements and selection Process?

Answer 1

The model is potentially beneficial for improving communication and collaboration among life cycle of
stakeholders in that it embeds action items from the IS, marketing and organizational realms. Many of
these action items are performed using improvisational skill. The addition of the outsourced human resources as a descriptive characteristic of the customer’s users. An iteration is one cycle in the spiral
model during which work activities—analysis, design, implementation—are used to complete a version

Approaches for selection of approaches Incudes:

? structured approach – system development using structured analysis, structured design, and
structured programming techniques
? structured programming – a programming approach where each module has one start point
and one end point and uses sequence, decision, and repetition constructs only
? top-down programming – the concept of dividing a complex program into a hierarchy of
program modules
? structured design – the design process of organizing a program into a set of modules and
organizing those modules into a hierarchical structure
? structure chart – a graphical diagram showing the hierarchical organization of modules
? structured analysis – a technique to determine what processing is required and to organize
those requirements by using structured analysis models
? data flow diagram (DFD) – a structured analysis model showing inputs, processes, storage,
and outputs of a system
? object-oriented approach – system development based on the view that a system is a set of
interacting objects that work together
? object – a thing in an information system that responds to messages by executing functions or
methods
? object-oriented analysis (OOA) – the process of identifying and defining the use cases and the
sets of objects (classes) in the new system
? object-oriented design (OOD) – defining all of the types of objects necessary to communicate
with people and devices in the system, showing how objects interact to complete tasks, and
refining the definition of each type of object so it can be implemented with a specific language
or environment
? object-oriented programming (OOP) – programming using object-oriented languages that
support object classes, inheritance, reuse, and encapsulation
development into more manageable mini-projects.
The core processes are
used to group a set of related activities together, much like a phase does in the predictive approach. In
fact, you can think of each iteration as a mini modified waterfall project with a very narrow scope.
Within the iteration you will do the various activities of the core processes much like a predictive
project.
was done in tandem with the addition of the same variable in the vendor’s descriptive variables. This
is possible, as in many closed and highly specialized industries, many of the organizational employees
today are outsourced employees, who are often sent from a common pool of HR outsourcing companies
and employees.
