Software Engineering Answers

Software used in an aircraft has to be developed using a different development process as an e-commerce web page. An operating system has to be developed differently from a word processor. In large software systems different parts may be developed using different process models. Suggest and justify the most appropriate generic software process model that might be used as a basis for managing the development of the following systems:

a) An interactive system for Bus passengers that finds Bus times from terminals installed in stations

b) Smart door lock system with automation and security

An algorithm that request a user to input their name and then stores their name in a variable called first name. Subsequently, algorithm should print out first name alone with the phrase "Hello,World".

Write few notes on the following ( not less than 3 pages 

Question 3 (Marks: 20) Design the interfaces for the new system.

The interfaces can either be drawn or generated using a programming language prototyping tool of your choice.

These interfaces should be provided in such an order that it clearly demonstrates how a student will be able to access the system to view an electronic report card containing their grades of all courses taken by him or her. Also provide an example of what an error message for the system will look like.

Criteria Mark Allocation Affordance: Do the controls on the various dialogs suggest their function? 2 Visibility: In terms of visibility, determine whether all functions that can be performed are clearly indicated so that the user knows what to do next.

(2) Consistency: Are the interfaces consistent in function and appearance? 2 Feedback: Do the interfaces offer feedback to the user?

(2 )Dialogs that yield closure: Are the tasks represented by the dialogs organised so that they have a clear beginning, middle, and end?

Question 2 (Marks: 20)

Question 1 (Marks: 20)

A Work Breakdown Structure (WBS) is a list of all the required individual activities and tasks for the project. A WBS is a very useful tool for estimating the amount of work to be done and to create a detailed work schedule.

NB: Research on the internet and the prescribed material about the WBS. As part of your project team you have been tasked to create the WBS for the SRS system.

Marks will be awarded as follows.

Criteria Mark Allocation All phases of SDLC included in WBS as tasks 5 At least five activities included in each task 5 Start Date

and End Date indicated on all tasks 4 Task Dependencies indicated (where necessary) 4 All activities identified follow a logical flow 2 Total: 20
