Some part is related to design where middle level or fresh experienced personnel enters with large numerical abilities to codify the system requirements and usually does not require management skills (Sommerville, 2004).
Some part is related to support issues which are trusted to fresh graduates who are assigned to understand the various system support issues and does not require enough management experience.

Problem: 2
Answer: a Figure 1: Task List Figure 2: Gantt chart Figure 3: Task Evaluator Figure 4: The red lines denote the critical activities
Answer b) The task “write use cases” does not fall under the critical path so allotting less time for the task would not reduce the overall time at all.
The tasks or activities along the critical path determine the project timing and its finish. The time critical activities must be capitalized so as to reduce the overall time for the entire project.
Problem 3: Answer: a
Answer: b
Problem 4. 1
Answer: a Not all programs are compatible to every installation which is why this proposal cannot be fully accepted. Program configurations which work in some installations may not work similarly to others. However, there are some independent programs that functions in all installations and does not need specific configurations. Read about Evolution of Job Design
In this case, skipping of desk checking is advised.
Answer: b Link testing with large amounts of data types of varied nature is an excellent proposal as it would bring about more precise decisions for data and its dependencies. The larger the amount of data included in the testing, the larger the scale of differences to be determined, hence, easily bringing about conditions and decisions for the system.
Answer: c A system testing with large amount of live data is also a great proposal as it would provide an in depth understanding of the basic features that strengthens the system’s functionality.
Testing is used for verification and validation of the system. Only exhaustive testing can show that a program is free from defects. However, exhaustive testing is somehow impossible because it is the Testing Policies that define the approach to be used in the system test. These policies include:
• all functions accessed through menus should be tested,
• combinations of functions accessed through the same menu should be tested,
• when user input is required, all functions must be tested to determine correct and incorrect input. The system testing also ensures validation and verification of the system.
Verification is demonstrating conformance to the specification whereas validation is checking that the system meets the customer’s needs. Validation is difficult because there are many different stakeholders with different needs who may use the system. Therefore, a system that meets one user’s needs may not meet the needs of a different user.
Problem 4. 2
Answer: a There are certain requirements that are needed before utilizing the system. First and foremost, the systems input and output should be analyzed as it may not be in its desired process.
In addition, the hardware and software must be compatible to the system requirements. And a system evaluation should be carried out to determine the different processes to handle every unique situation. This process would enable the system to function at its best and ensure greater usability and scalability. Therefore, if the system is not evaluated systematically then tasks to be checked such as consistency and scalability for final system response and proper output mechanism will be overlooked and disregarded.
