7COM1024 - Doolan Executive Taxi Service Online (DETO) - Software Measurement and Goal - Engineering Assignment Help

Assignment Task - 

This assessment comprises three tasks and is in two parts as stated below. Part 1: Software Measurement and Goal Question Metric 

Doolan Executive Taxi Service Online (DETO), is a company specialised in providing local  and national taxi services for executives to ferry them to and from private helicopter and  small airplane landing points across the country. The company employs over 40 drivers and  has more than 1500 executive clients. 

They have a website which includes amongst other features a simple web-based email  system which allows users to attach up to five attachments to each new email. In  accordance with their own policy and rules, before the uploading process actually begins,  the system checks that attachments are not larger than 100Mb each, and that no attachment  is a file type which is not allowed (by comparing the file extension against a list of extensions  saved to the system). If the uploads pass both tests, the files can be successfully uploaded  on the mail servers and eventually sent to the recipient(s).  

If either of the above two constraints is breached, an alert message to the user is displayed.  Once the procedure for uploading attachments has been completed, the user is redirected to  the main email system web page, on which a message box is displayed including the  number of attachments, their full name (including extensions) and size, which are to be  enclosed in the email yet to be sent. 

Task 1: To enable a later calculation of the size of this part of the system in Unadjusted  Function Points, use the description above to identify the elements of each of the following  types, stating their names and the total number of each type.  

• Function Type Elements Number of  elements 
• Names of elements 
• User input 
• Reports to the user Prompts and responses 
• Interfaces to external  systems/files 
• Internal Logical Files 

Based on your own judgement, find out the realistic weight for each “Functional Type  elements” and derive the unadjusted Functional Point.  

Note: You can use average weight and do not need to calculate the adjusted Functional  Point. 

Task 2: as an independent consultant, you have been asked to perform a Goal-Question Metric (GQM) analysis into how effective the DETO website is in order to suggest some  improvements to its designers., especially as attracting new customers is a key priority for  the company. 

Identify “the objects under measurement” for the GQM template. 

• Analyze 
• The object under measurement
• For the Purpose of
• With Respect to
• From the viewpoint of
• In the Context of Based on the above GQM template, identify two (consistently derived) measurable goals for  the company. For each goal list two relevant questions. For each question give at least one metric you would want to collect.  

Part 2: Software Process Models 

Task 3: Now the company is considering using a highly sophisticated and leading edge on board navigation system for the next generation of the company’s cars. The company has  heard that rapid development of the software development process may result in a high-quality  product which can be released quickly. This is of interest to this company in order to gain  competitive advantage and quality is of vital importance since if cars are out of use money is  lost and reputation may suffer. 

Senior management have approached you to help them to compare the suitability of TWO software process models that might be used as a basis for the development of the on-board  navigation system and to make sure that this system integrates fully with the company’s  website. 

In no more than 2000 words discuss why your chosen software process models are a suitable  approach for this case study. In your discussion ensure to include the general characteristics  of the process models that make it so and any differentiating characteristics of the proposed  two models compared to others. Include details of the issues that will need to be addressed  for this software development and provide an explanation of the risks and pitfalls in managing  a software project such as this. 

You are required to include an in-depth discussion using your own words and provide a  breadth of references to support your arguments using the Harvard Referencing System. At  the very least 10 sources are expected. You are not permitted to use bullet points, lecture  materials or diagrams for task 3.
