PHASE 3:

 SYSTEMS DESIGN

Systems design consists of 3 tasks..

• Designing alternative systems
• Selecting the best system 

• Writing a systems design report

I will guide you

in order

to make you easy to

understand...

FIRST,

Please try to look at this below illustration..

This is just to make

you easier to keep in your mind

on 

how this systems design

works..

  

How to design the alternative systems??

For a beginning, 

you need to evaluate each alternative systems 

for feasibility..

In this case,

it includes of 

economic, technical and operational feasibility.. 

You must not familiar with these terms..

similar also with me..

but,

I had already found theirs meaning

from the Computing2010 website..

Since the Computing2010

is the main source

where i can get information

about this IT subject,

thus,

  I need to take advantage

in using its website

to get the meaning..

heheh...

Ok,

Now back to the meaning of each of them.

• Economic feasibility

 

Justifying the costs of a new system

to the benefits it promises.  

• Technical feasibility

 

Making sure hardware, software, and training

will be available

to facilitate the design

of a new system.

• Operational feasibility

 

Making sure the design

of a new system

will be able to function

within the existing framework

of an organization.

After you had come up with those feasibility,

now you need to

Selecting the best system

The selected system must be able being modified or changed over time, flexible enough, fit in with the organization's overall system, and benefits worth the costs.

Lastly, you need to

write the systems design report 

by include the costs and benefits of

all the alternatives and

recommend proceeding alternative.
