Process: A Process is a set of related activities that leads to the production of the software. These activities may involve the development of the software from the scratch, or, modifying an existing system.

PRODUCT: A product is designed to continually create value for customers by solving their problems. Products have more permanence, are living entities which we deliver quickly, iterate constantly, and are not something that we just walk away from.

ii.            Differentiate between Structured Analysis and Object Oriented Analysis?

ANSWER:

In Structured Analysis, the focus is only on process and procedures. Modeling techniques used in it are DFD (Data Flow Diagram), Flowcharts etc. This approach is old and is not preferred.

Object Oriented Analysis, put more focus on capturing the real world objects in the current scenario that are of importance to the system. It stresses more on data structure and less on procedural structure.

iii.            What is Closed System?

ANSWER:

A system in which the specifications are kept secret to prevent interference from third parties. It inhibits third-party software from being installed; it keeps third-party hardware from interoperating with it, and it prevents third-party enhancements from improving the product.

iv.            Define SCM?

ANSWER:

Software configuration management (SCM) is a set of activities that have been developed to manage change throughout the life cycle of computer software. SCM is a software quality assurance activity that is applied throughout the software process.

v.            What’s a CASE Tool?

ANSWER:

CASE tools are set of software application programs, which are used to automate SDLC activities. CASE tools are used by software project managers, analysts and engineers to develop software system.

vi.            What is SWOT Analysis?

vii.            What is Software Re-Engineering?

ANSWER:

Software reengineering uses analytical techniques to identify potential quality and performance improvements in an information system. Software reengineering is used to simplify operations, reduce costs, and improve quality.

viii.            What is RMMM?

ANSWER:

RMMM is a risk management strategy that can be defined as a software project plan or the risk management steps. It can be organized into a separate Risk Mitigation, Monitoring and Management Plan.

Stakeholders include the management group responsible for the system, the users (sometimes called end users) inside and outside the company who will interact with the system, and IT staff members, such as systems analysts, programmers, and network administrators who develop and support the system.

x.            What’s the difference between testing and debugging?

ANSWER:

Testing is a process of finding bugs or errors in a software product that is done manually by tester or can be automated.

Debugging is a process of fixing the bugs found in testing phase. Programmer or developer is responsible for debugging and it can’t be automated.

xi.            Write down the names of different phases of Rational Unified Process?

ANSWER:

1.      Planning

2.      Modeling

3.      Construction

4.      Development

5.      Communication

xii.            What is System Testing?

ANSWER:

System testing is a final testing process that verifies that all elements mesh properly and that overall system function/performance is achieved. A system test includes all typical processing situations and is intended to assure users, developers, and managers that the program meets all specifications and that all necessary features have been included.

xiii.            What is Gantt chart?

ANSWER:

Gantt chart is a horizontal bar chart that illustrates a schedule.  a Gantt chart is a visual view of tasks scheduled over time. Gantt charts are used for planning projects of all sizes and they are a useful way of showing what work is scheduled to be done on a specific day.

Gantt as a production control technique and still are in common use.

An FDD is a top-down representation of a function or process and you would use one to model a business functions and show how they are organized into lower-level process.

xv.            What is Extreme Programming?

ANSWER:
