Scenario
Please read this scenario prior to answering the question
ArchiSurance senior management, board members, customers and major stockholders have long
been concerned about disaster resiliency in light of the company’s heavy reliance on a single data
center. The data center is located in an area that is prone to flooding and earthquakes, according
to expert assessments done by consultants retained for this purpose. In addition, the data center
is located under a busy cafeteria, and water occasionally leaks through its ceiling.
To adoress these problems, ArchiSurance has developed a plan to move from its current data
center to a pair of ready-to-use data centers in separate cities. The data center move is designed
to reduce the risk of business interruption, reduce both planned and unplanned downtime for
critical applications, and reassure ArchiSurance stakeholders. However, a number of limitations
make theplanned transition to the new data centers particularly challenging. A number of critical
ArchiSurance applications cannot be offline for more than an hour, and any downtime for these
application must only occur in certain four-hour windows each weekend. Also, the move cannot
occur during quarterly or year-end closing periods in order to avoid interrupting critical processing.
Fulfillment of these specific type of requirements will reduce the risk of business interruption from
the data center move activities themselves.
ArchiSurance management has therefore planned a multi-phase data center transformation
program. All of the activities in each phase are necessary to ensure a progression of stable and
fully functional data center configurations. The first phase consists of detailed scheduling and
planning to produce a comprehensive transformation plan that meets ArchiSurance timing and
scheduling requirements During the second phase, ArchiSurance is to contract for the hardware
and software required for the new datacenters,as well for refunds for the hardware and software to
be returned from the current data center once it is shut down. During the third phase, the new data
centers are to be set up, and the new hardware and software are to be tested in parallel with what
is already in production. The actual transition between the old and new data centers occurs in the
fourth phase, and the fifth phase involves shutting down and dismantling the old data center, and
returning its hardware and software for contracted refunds. Phases two through five are each to be
initiated when specific conditions are met in the previous phase.
Refer to the Scenario
The newly hired program manager for data center transformation has asked you to describe the
program implementation plan. You must express each of the plan phases as a separate work
package with specific deliverables. You must also show the relationships between phases along
with how each phase contributes to a particular stable data center state.
