Question
1) What strategy (SDLC, RAD, outsourcing, etc.) did Arizona State University use to develop its new ERP system? What were the pros and the cons of the strategy?
2) What approach was used to implement its new ERP system (parallel, plunge, pilot, or phased)? What were the pros and the cons of the implementation approach?

Explanation / Answer
Question:- 1) What strategy did Arizona state university use to develop its new ERP system?What were the pros and cons of the strategy?
Answer:- If you are thinking about implementing ERP system , you may be wondering , What are the different ERP implementation stratgies? and which is best for my unversirty.
As per you university the big-bang ERP stratgies is most suitable.
About Big-Bang:-
This is like ripping off the band-aid; it may hurt, but only for second! ERP implementation happens in one big action. All users move to the new system on a given date.

Question 2) What approach was used to implement its new ERP system (parallel,plunge,pilot, or phased)?what were the pros and the cons of the implementation approach?
Answer:- Parallel :-
In a parallel changeover, the new system runs simultaneously with the old for a given period of time. Of all the techniques, this tends to be the most popular, mainly because it carries the lowest risk. If something goes wrong at any point, the entire system can be reverted back to its original state. A primary disadvantage in running two systems at the same time is higher costs. The parallel changeover process also can be quite time-consuming.
Plunge:-
Plunge changeover, also referred to as immediate replacement, tends to be the least favorite of the changeover techniques. In a direct changeover, the entire system is replaced in an instant. Basically, as soon as the new system is powered up, the old system is shut down. This type of changeover carries the most risk because, if something goes wrong, reverting back to the old system usually is impossible. Using the direct changeover technique tends to work best in situations where a system failure isn't critical enough to result in a disaster for the company.
Phased
The phased changeover technique is considered a compromise between parallel and direct changeovers. In a phased changeover, the new system is implemented one stage at a time. As an example, consider a company working toward installing a new financial system. Implementing the new system one department at a time, the company converts accounts receivable, accounts payable, payroll, and so on. Advantages to phased changeovers are their low cost and isolated errors. The main disadvantage is the process takes a long time to complete because phases need to be implemented separately.
Pilot
With a pilot changeover, the new system is tried out at a test site before launching it company-wide. For example, a bank may first test the system at one of its branches. This branch is referred to as the pilot, or beta, site for the program. Since parallel changeovers tend to be expensive, using the pilot changeover technique allows companies to run the new system next to their old but on a much smaller scale. This makes the pilot changeover method much more cost-effective. After the kinks are worked out of the system at the test site, companies usually opt to use the direct changeover technique to launch the system company-wide.
Question 3) Discuss the ethics associated with a system implementation strategy that accepts employee and customer pain and confussion in order to accelerate implementation and cost savings.
