Question

An application that computes the velocity of a plane b. A case management system for detecting potential terrorist activity c. An electronic trading network between vendors and suppliers d. An integrated set of tools for designing commercial heating/cooling systems e. An electronic voting system In several chapters, we have emphasized the importance of efficient change management as a key component of the ability to cost-effectively maintain an application. Discuss the various types of changes one should anticipate in choosing an application architecture for each of the applications listed in Exercise 1. For example, one might expect to have to deal with new types of thermostats when designing commercial heating/cooling systems. What generalizations could one make about which types of application architecture are best suited to different types of applications?

Explanation / Answer

Application

Application architecture

Change Management

Application to compute velocity of a plane

Distance between the source and the destination city divided time may be 1 way to find the speed.

Implementing the new application means the parties involved will need to get familiar with the application screen, understand the presentation of data.

The Fuel consumption rate * time is another way pilot can calculate the speed

It is needed to have parallel run of applications with the methods that pilot have been using for a long time, compare the results and train the all involved staff.

Vector arithmetic can be another way to calculate the speed.

It may be needed to set some parameters and initiate the application for each plane.

Getting the vector positions by radar and then preparing the clock time matrix there can be an application to calculate the accurate speed. The wind speed sensor can provide additional inputs.

Detecting potential terrorist attack

Inputs based on social media, online chats/ discussion forum

The traditional way of having smart and intelligent police-force shifting to having a knowledge management based process and solution leads to conflict between the senior team and the process oriented team.

Inputs based on material movement

It is important to utilize the methods used by the senior team and keep everyone in the sync about the changes.

Inputs based on tracking suspicious people

Activities that are different than usual as tracked by imaging and recording software

Electronic trading network between vendors and suppliers

The changes may be notified in terms of requirements and prices digitally.

Digitally savvy people who respond fast to the information that is received in the notifications will be leading suppliers/vendors

The traditional method of telephone calls or being physically present might get replaced by digital document workflows.

The traders who have been in the network for long must adapt to the new system where the responses need to be sent online on-time.

The supplier/Vendor should have product specifications/prices etc in the form that can be circulated easily over the digital network.

Electronic Voting System

To have the digital boxes at all the places

The people need to have trust in the new method

The internet/intranet/or a way to upload the data from each voting booth to the centralized system in a secure and a cost-effective way

Education and transparent information and thorough testing of the new system is necessary.

The generalization that can be made is:

1. Prototyping works in some cases to make sure that before purchasing equipments for every location complete testing and changes need to be done at prototype level

e.g. size and type and design of the voting machine at selected booths, gather feedback from users and then implement.

2. Changes are needed in the way inputs are collected. There may be sensors used and people need to have complete understanding of how to work with the new system. e.g. not switching on certain sensors or not configuring them properly will lead to the change being ineffective and project failure.

3. Robust processes: As the process and workflows are important it is needed that all the involved members are happy to use the new methods e.g. in potential terrorist detection

4. Notifications and online data is important and standardization across various involved members plays key role e.g. SKU numbers are understood by all vendors and suppliers in the notebook.

5. Digitally Savvy members e.g. use of mobile devices, pdas, notebooks etc for fast response
