Roark has just joined the company and in his role as lead analyst, he will be responsible for determining which systems development method the team uses to create the new application for a major medical supplier.It is a new day at the firm. Roark has been in place for a few weeks, strengthening the communications skills of his employees, getting them to work much better together. Now, the challenge that he faces is not an internal one; it lies with the client, which is increasingly showing itself to be incapable of sticking with decisions. Roark, based on his past experience with other clients like this, is afraid that the client will throw them a curveball and want to make changes late in the game — but that they also will be unwilling to absorb the costs of those changes. For this reason, Roark eliminates which of the following methods of development?

Project assessment is part of post-implementation.True

What is NOT normally part of transitioning to a new system?Developing the user interface screens

Which is NOT a step in Lewin's model for managing organization changeProgram

Lewin's Change Management ModelUnfreeze- first stage of change involves preparing the organization to accept that change is necessary, which involves break down the existing status quo before you can build up a new way of operating.

Change- the change stage is where people begin to resolve their uncertainty and look for new ways to do things. People start to believe and act in ways that support the new direction.

Refreeze- the organization is ready to refreeze when the changes are taking shape and people have embraced the new ways of working, The outward signs of the refreeze are a stable organization chart, consistent job descriptions, and so on. The refreeze stage also needs to help people and the organization internalize or institutionalize the changes. This means making sure that the changes are used all the time; and that they are incorporated into everyday business. With a new sense of stability, employees feel confident and comfortable with the new ways of working.

Plans to handle potential business disruption due to technical problems during conversion are covered in the:

Business Contingency Plan

One of the problems with a parallel conversion is:the users have to enter data into both systems

If a trainer has been hired to train all staff before the new system goes 'live', it might be best to use:phased conversion

Frequently, as people get used to certain ways of doing things, they view their job in terms of those processes rather than in terms of the business goals of serving customers.True

Knowing that sometimes things happen due to technical problems when implementing a new system is a great reason to have a business contingency plan.True

Part of the migration / transition plan should include helping people adopt the new system.True

Post-implementation activities include:Support: providing assistance in the use of the new systemMaintenance: continuing the refine and improve the systemProject Assessment: analyzing the project to understand what activities were done well- and should be repeated-and what activities need improvement in future projects.

The three key roles in any major organization change are:

1. Project sponsor is the person or organizational unit that wants the change. 2. Change agent is the person or group who leads the change effort.3. Potential adopter is the person or group who must actually do the changing.

Two basic strategies to motivating adoption:Informational strategy- to convince potential adopters that the change is for the better. (works best when more benefits than costs)Political strategy- organizational power, not information, is used to motivate change. (this is used when the cost-benefit set of the target adopters has more costs than benefits)

Change requests typically come from five sources:1. most common is problem reports from the operations group that identifies bugs in the system that must be fixed.2. enhancements to the systems from users. 3. other system development projects4. those that occur when underlying software or networks change. 5. Senior management. (driven by changes in the organization's strategy)

Four types of databases that are likely to be encountered during a project:legacy, relational, object, and multidimensional.

Legacy- use older and sometimes outdated technology and are rarely used to develop new technology.Relational- most popular kind of database for app dev. today. (based on collections of tables that are related to each other through common fields known as foreign keys) Object- contain data and processes that

are represented by object classes, and relationships btw object classes are shown by encapsulating one object class within another and are mainly used for multimedia applications (graphics, video & sound)Multidimensional- popular with the increase in data warehousing. it stores pre-calculated quantitative information (totals, averages) at the intersection of dimensions (time, salesperson, product) to support appl that require data to be sliced and diced.

Direct Conversion strategy stylestopping the old system and starting the new system on a given date (high risk, Low resources, Low time, Hi Cost)

Parallel Conversion strategy styleusing both old and new systems until it is evident that the new system performs correctly. (Low risk, high Resources, Hi potential/time , Hi Cost)

Pilot Conversion location styleimplementation process that introduces the new system in one part of the organization on a trial basis; when new system is working properly, it is introduced in other parts of the organization. (Med Risk, Med resources, Med time, Med cost)
