Note: Answer all questions. Kindly note that answers for 10 marks questions should be approximately of 400 words. Each question is followed by evaluation scheme.

Q. 1 Process patterns are the results of applying abstraction to recurring processes and process components. Process patterns are collections of general techniques, actions, and/or tasks (activities) for developing object-oriented software. Justify the above statement. Explain with an example for each, the different types of process patterns in the ascending order of abstraction level.

Ans : Process patterns relate to the strategies that software professionals employ to solve problems that recur across organizations . Each process pattern describes a collection of general techniques, actions, and/or tasks for developing object-oriented software. An important feature of process patterns is that they suggest what to do, but not details of how to do something. Hence process patterns are reusable building blocks from which

Q. 2 Software estimation is the first phase of project planning and it is the process of judging a software product and solving the problem associated with the software project. We follow some important steps to achieve reliable cost and effort estimates. Explain the different estimation models and estimation techniques.

Ans : Different estimation models:

There are many models for software estimation available and prevalent in the industry. Researchers have been working on formal estimation techniques since 1960. Early work in estimation which was typically based on regression analysis or mathematical models of other domains, work during 1970s and 1980s derived models from historical data of

Q. 3 Empirical software solutions is a small manufacture based company who have a single product in the public access and security domain. The information system which they possess gives details pertaining to the presence of individuals at specific locations and also checks and issues security badges.

The software of the system is connected to specially designed hardware peripherals along with a well-defined LAN network connection. The system handles several aspects ranging from computing from database manipulation, peripheral hardware ti image handling. This company uses both software as well as hardware, and incorporates latest technologies, like networking and device drivers.

Due to the pressure from customers and the competition, they were in need of a structured software process. There was no standardized development process. Most of their work was based on customer requests. Every time a new request from customer came in, more additions were made to the product. A new version of the software was installed at the customer’s site when requested by the customer. All the queries related to technical support, modifications made to the system were handled by the development team. There was no specific design methodology followed and each developer used his own method of working. Apart from the user manual, there was no other documentation found held.

Challenges:

Introduction of reuse framework and method into the company

Gain support from the top management for the reuse program, as introduction of reuse program can affect all parts of the software production process.

Suggestions were made to set up the reuse program along with the associated cost and risk involved in setting up the reuse program.

a. Explain the challenges faced by the empirical software solutions

b. Give some suggestions to overcome the challenges.

c. Explain the classifications and advantages of software reuse.

Ans:  Challenges faced by the empirical software solutions :

• The major challenge faced by the empirical software solutions was lack of standardized development process.
• They need to made additions to the products on the basis of the need of the customer.
• They had to bring such kind of changes over and over again.
• Introduction of reuse framework and method into the company
• Gain support from the top
•  
• Q.4 Suppose you are assigned the task to analyse the various factors involved in your project, explain how will you gather information and analyse the task

Ans : System analysis :

Systems analysis is the study of sets of interacting entities, including computer systems analysis. According to the Merriam-Webstre dictionary, system analysis is the process of studying a procedure or business in order to identify its goals and purposes and create systems and procedures that will achieve them in an efficient way. Analysis and synthesis, as scientific methods, always go hand in hand; they complement one another. Every synthesis is built upon the results of a preceding analysis, and every analysis requires a subsequent

Q.5 Write short note on

a. Unit testing

b. System testing

c. Debugging

d. Verification and validation

Ans :  a. Unit testing :

Unit testing, also known as component testing, refers to tests that verify the functionality of a specific section of code, usually at the function level. In an object-oriented environment, this is usually at the class level, and the minimal unit tests include the constructors and destructors.

These types of tests are usually written by developers as they work on code (white-box style), to ensure that the specific function is working

b. System testing :

System testing of software or hardware is testing conducted on a complete, integrated system to evaluate the system's compliance with its specified requirements. System testing falls within the scope of black box testing, and as such, should require no knowledge of the inner design of the code or logic. As a rule, system testing takes, as its input, all of the "integrated" software components that have passed integration testing

c. Debugging :

Debugging is a methodical process of finding and reducing the number of bugs, or defects, in a computer program or a piece of electronic hardware, thus making it behave as expected. Debugging tends to be harder when various subsystems are tightly coupled, as changes in one may cause bugs to emerge in another. Many books have been

d. Verification and validation:

In software project management, software testing, and software engineering, verification and validation (V&V) is the process of checking that a software system meets specifications and that it fulfills its intended purpose. It may also be referred to as software quality control. It is normally the responsibility of software testers as part of the

Q.6 Briefly describe the concept of polymorphism by using the automobile class as an example.

Ans : a. Example of automobile class :

The Vehicle class would include instance variables such as registration Number and owner and instance methods such as transfer Ownership(). These are variables and methods common to all vehicles. The three subclasses of Vehicle -- Car, Truck, and Motorcycle -- could then be used to hold variables and methods specific to particular types of vehicles. The Car class might add an instance variable number Of Doors, the Truck class might
