In this project, the Total Operations Expense would amount to £50.90/hour or £12216/month for the whole 30 days of operations. The breakdown of the expenses is implicated here on:
Operations Expense:
Personnel cost per hour: £38.40/hour
Project Supervisor x 1: £13.00/hour
Programmer x 2:
Chief programmer x 1: £11.00/hour
Associate programmer x 1: £6.90/hour
Maintenance team x 3:
Maintenance Crew x 4: £7.5/hour
(Latency check, server check, customer response/feedback, prototype testing)
Utilities: £12.5/hour
Food, Electricity, Water, City Services
Total Operation Expense per hour: £50.90 x 30 = £12216/month
Human Factors Consultant 20 days @ 650/day £13000
Original profit from Website per month: £25000
As seen from the breakdown of expense, the total cost of personnel per hour would amount £38.40/hour, which includes a chief programmer, an associate programmer, and 4 maintenance crews working to ensure the stability of the website (latency, server, and prototype testing) and the usability and efficiency of its interface. The role of the prototype tester within the team is important because their main function is to check for any technical difficulties that could present itself after system release. Thus, if changes are to be made after system release, then costs would be higher as compared to implementing changes during the prototype stage. The difference in costs is implicated as follows:
Cost of Change for prototype stage
Hours per change3
Hourly Staff Costs£38.40/hour
Cost of Each Change£115.2
Cost of Change after system release
Hours per change24
Hourly Staff Costs£38.40/hour
Cost of Each Change£921.6
Total savings due to prototype tester £806.4
Also, as stated from the project outline, the consideration of human factors for usability engineering of the website, would is predicted to reduce turnover rates by about 25%. This system, therefore, would help save around 480 hours of effort and £4608 per hours of operation per year, which includes both the training and total personnel cost per hour. The breakdown of the cost for this is implicated below:
Training hours x reduction (25%) 80 (days) x 0.25 = 20 saving in training hours/trainee
Personnel cost per hour (average) £38.40
Trainees x reduction in training time 6 x 20 x 38.40 = £4608 Cost benefit per year
x cost per person
Aside from this, another benefit of the project on usability engineering of the website would be the total service costs for attending to potential technical issues in the long r...
