Question 1: Problem Specification Currently, the Advantage Energy Technology (TEA) data centre is located on the second floor of a renovated old bank building. The company is moving to a new, one-level building located in the recently developed industrial complex. On February 1st, Brian is formally assigned the task by the UP of Operations with the following guidelines: From start to finish, it is anticipated the entire project will take three to four months to complete. It is essential that Eats 235 clients suffer no downtime.
The UP advises Brian to come back to the Executive Committee on February 15, with a presentation on the scope of the project that includes costs, “first cut” timeline, and proposed team members. Brian had some preliminary discussions with some of Teat’s managers from each of the functional departments and then arranged for a full day scope meeting on February 4 with a few of the angers and technical representatives from Operations, systems, facilities, and applications. The scope team determined the following: Three to four month is a feasible project timeline.
First-cut cost estimate is $80,000 – $90,000. Critical to the “no-downtime” requirement is the need to completely rely on Teat’s remote disaster recovery “hot” site for full functionality. Brian will serve a project manager of a team consisting of one team member each from facilities, operations/systems, operations/telecommunications, systems & applications and customer service. Briar’s report on this to the Executive Committee was approved. He recruited his team and scheduled their first team meeting (March 1) as the initial task of his project planning process.
Once the initial meeting is conducted Brian can hire the contractors to renovate the new data center. During this time Brian will figure out how to design the network. Brian estimates that screening and hiring a contractor will take about one week and that the network design will take about two weeks. The new center requires a new ventilations system. The manufacturer’s requirements include an ambient temperature of 67 degrees to keep all of the data servers running at optimal speeds. The ventilation system has a lead time of three weeks.
Brian will also need to order new racks to hold servers, switches, and other network devices. The racks have a two week delivery time. The data center supervisor requested that Brian replace all of the old power supplies and data cables. Brian will need to order these as well. Because Brian has a great relationship with the vendor, they guarantee that it will take only one week lead time for the power supplies and the data cables. Once the new ventilation system and rack arrive, Brian can begin installing them. It will take en week to install the ventilation system and three weeks to install the racks.
The renovation of the new data center can begin as soon as the contractors have been hired. The contractors tell Brian that construction will take 20 days. Once the construction begins and before Brian installs the ventilation system and racks, the city inspector must approve the construction of the raised floor. The city inspector will take two days to approve the infrastructure. After the city inspection and after the new power supplies and cables have arrived, Brian can install the power supplies and run the cables.
Brian estimates that it will aka 5 days to install the power supplies and one week to run all of the data cables. Before Brian can assign an actual date for taking the network offline and switching to the hot remote site, he must get approval from each of the functional units (“Switchover Approval”). Meetings with each of the functional units will require one week. During this time he can initiate a power check to ensure that each of the rack has sufficient voltage. This will require only one day. Upon completion of the power checks, he can take one week to install his test servers.
The test servers will test all of the primary network functions and act as safeguard before the network is taken offline. The batteries must be charged; ventilation installed, and test servers up and running before management can be assured that the new infrastructure is safe, which will take two days. Then they will sign off the Primary Systems check, taking one day of intense meetings. They will also set an official date for the network move. Brian is happy that everything has gone well thus far and is convinced that the move will just go as smoothly.
Now that an official date is set, the network will be shut down for a day. Brian must move all of the network components to the new ATA center. Brian will do the move over the weekend (two days) when user traffic is at low point. Key Notes: C] A working day is Monday, Tuesday, Wednesday, Thursday and Friday (am pm). D Staffs work Mondays through Friday. C] A penalty of $1 0,000 per day of delay beyond August 25, 2014, is entered into the contract. њ The last Friday of every month is a sports day for the company.

Bill suspects that the system may not be completely secure, though he has not had the opportunity to inspect it as thoroughly as he would like. Bill’s manager however instructs Bill to give a favorable report to the court, since his manager has good elation’s with the company that designed the security features for that company. Bill does as he was instructed.

That is identify the relevant clauses from the six values described in the code of ethics. (10 marks) Hint: Your answers must appear similar to how the case studies in the ACS Code of Ethics Case Studies document have been discussed. Question b): Engineer A is an electrical engineer working in quality control at a computer chip plant. Engineer Ass staff generally identifies defects in manufactured chips at a rate of 1 in 150.
The general industry practice is for defective chips to be repaired or destroyed. Engineer B, Engineer Ass supervisor, recently announced that defective chips are to be destroyed, because it is more expensive to repair a defective chip than it is to make a new chip. Engineer A proceeds on the basis of Engineer Bi’s instructions. A few months later, Engineer B informs Engineer A that Engineer Ass quality control staff is rejecting too many chips, which is having an effect on overall plant output and, ultimately, company profitability.
Engineer B advises Engineer Ass staff to allow a higher percentage of chips to pass through quality control. Engineer B notes that in the end, these issues can be best handled under the company’s warranty policy under which the company agrees to replace defective chips based upon customer complaints. Engineer A has concerns as to whether this approach is in the best interest of the company or its clients. Required: i. What are Engineer Ass ethical obligations under these circumstances. [Using the above case study discuss the aspects of ethical behavior with references to relevant clauses of the PENN Code of Ethics.
