42. Read the need statement of an electronic company below (5 Marks): In September 2004 IDC, a market research firm, reported that the market for portable mp3 players would boom over the next five years into a $58 billion industry. The IDC reasoned that the portable flash players are going to overshadow the much publicized hard drive based players. Due to the falling prices in flash memory and technological breakthroughs that have resulted in higher capacity flash cards the market is raw for portable flash players. IDC reported that 12.5 million flash players were sold in 2003 and predicts that the number will jump four-fold to 50 million units in 2008. Currently there exists a market for portable flash player and our company wants to have a big share of this market. We do not want to be a mere imitator, saturating the market with just another MP3 player. We intend to take this concept a step further. We asked ourselvesWhat would set our player apart from the dozens of players that are already out there in the market? Our solution is to design a portable player that is highly immune to the vagaries and abuses of users. Water proof walkman and shock resistant CD players have been in the market for decades, but there is no portable flash player that can withstand continuous shocks, exposure to water, and exposure to extreme temperatures. Our intention is to fill this void and give customers a player that they can run or jog with, listen to their favorite tunes while swimming or relaxing in a Swedish spa or hiking at great altitudes. 1. Identify all the stakeholders for the above proposed portable flash player. 43. An Early Warning Pothole Detection System (EWPDS) 7 Marks: Below are some need statements for a proposed EWPDS and 2 groups of stakeholders' requirements. Analyze them carefully and come up with 5 Acceptance Criteria and also 3 alternative concepts. Evaluate the 3 concepts for the software and hardware that will drive the detection of the potholes based on the requirements. Use Pugh Matrix for your evaluation and recommend one of the 3 concepts for selection. Need Statement: - "Don't you hate it when you're in your brand new car and you crack a rim hitting a pothole!" - Many of today's cars are equipped with expensive alloy wheels, driving up the cost of car repairs due to pothole - Older steel wheels are stronger, more resistant to bumps on the road, however are less attractive - Alloy wheels selected for aesthetics and light weight - Alloy wheels selected for aesthetics and light weight Stakeholder requirements: (Active/Direct) Customer Requirements Warn a driver of pothole hazards on the road Provide an audio and visual warning when a pothole is detected Pothole warning should occur with ample time for the vehicle to avoid the hazard A pothole warning does not negatively impact a driver's ability to operate the vehicle The system is very accurate at detecting pothole hazards System can be turned on/off from the vehicle cabin When turned on the system does not require user intervention to operate The system does not impact the driving performance of the vehicle (acceleration, cornering, braking) The system does not affect the outward appearance of the vehicle The initial purchase cost of the system is low The maintenance costs of the system are low The system requires infrequent maintenance (Passive/Indirect) Automobile manufactures Vehicle physical designs do not need to change in order to install the system Vehicle physical designs do not need to change in order to incorporate the system The system does not affect the outward appearance of the vehicle The system does not impact the driving performance of the vehicle (acceleration, cornering, braking) The system does not negatively impact the performance of other vehicle systems (HVAC, audio, driver controls) Insurance companies Warn a driver of pothole hazards on the road Pothole warning should occur with ample time for the vehicle to avoid the hazard When turned on the system does not require user intervention to operate A pothole warning does not negatively impact a driver's ability to operate the vehicle The system is very accurate at detecting pothole hazard Acceptance Criteria: (3 marks) Acceptance Criteria: (3 marks) Concept Evaluation (4 marks) 44. Create a set of use cases for an online university registration system. (8 Marks) The system should enable the staff of each academic department to examine the courses offered by their department, add and remove courses, and change the information about them (e.g., the maximum number of students permitted). It should permit students to examine currently available courses, add and drop courses to and from their schedules, and examine the courses for which they are enrolled. Department staff should be able to print a variety of reports about the courses and the students enrolled in them. The system should ensure that no student takes too many courses and that students who have any unpaid fees are not permitted to register. (Assume that a fees data store is maintained by the university's financial office, which the registration system accesses but does not change).
