1. Process patterns are abstractions of recurring processes and components that help develop object-oriented software. They range from general techniques to specific tasks and activities, ordered from least to most abstract. Examples include creational, structural, and behavioral patterns. 2. Software estimation models and techniques help achieve reliable cost and effort estimates during project planning. Estimation models include algorithmic and non-algorithmic models. Techniques include expert judgment, analogy, and parametric modeling. 3. An empirical software solutions company faced challenges like a lack of standardized development processes and documentation. Suggestions included introducing a reuse framework, gaining management support, and setting up a reuse program with associated costs and risks. Software reuse classifications and

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.

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.

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.
