Feasibility Criteria Wt. Candidate 1 Candidate 2 Candidate 3 Candidate ..

Operational Feasibility

Functionality. A description of to whatdegree the candidate would benefit theorganization and how well the systemwould work.

Political. A description of how wellreceived this solution would be fromboth user management, user, andorganization perspective.

30% Only supports MemberServices requirements andcurrent business processeswould have to be modified totake advantage of softwarefunctionality

Score: 60

Fully supports user requiredfunctionality.

Score: 100


Score: 100

Technical Feasibility

Technology. An assessment of thematurity, availability (or ability toacquire), and desirability of thecomputer technology needed to supportthis candidate.

Expertise. An assessment to thetechnical expertise needed to develop,operate, and maintain the candidatesystem.

30% Current production release ofPlatinum Plus package isversion 1.0 and has only beenon the market for 6 weeks.Maturity of product is a riskand company charges anadditional monthly fee fortechnical support.

Required to hire or train C++expertise to performmodifications for integrationrequirements.

Score: 50

Although current technicalstaff has only Powerbuilderexperience, the senioranalysts who saw the MSVisual Basic demonstrationand presentation, has agreedthe transition will be simpleand finding experienced VBprogrammers will be easierthan finding Powerbuilderprogrammers and at a muchcheaper cost.

MS Visual Basic 5.0 is amature technology based onversion number.

Score: 95

Although current technicalstaff is comfortable withPowerbuilder, management isconcerned with recentacquisition of Powerbuilderby Sybase Inc.MS SQL Server is a currentcompany standard andcompetes with SYBASE inthe Client/Server DBMSmarket. Because of this wehave no guarantee futureversions of Powerbuilderwill “play well” with ourcurrent version SQL Server.

Modeling Application Architecture & Information System Processes

Physical Data Flow Diagrams

Physical Processes:

Process names use the action verb + object clause convention,

however, the name is preceded or followed by an

implementation method. The format is:

• implementation method : action verb + object clause

• action verb + object clause : implementation method

If a logical process is to be implemented partially by people and

partially by software, it must be split into separate physical

processes and appropriate data flows must be added between

the physical processes.

• The name of a physical process to be performed by people, not

software, should indicate who will perform that process.

Modeling Application Architecture & Information System Processes

Physical Data Flow Diagrams

Physical Data Stores:

Each data store on the logical DFD now represents a data entity

on a normalized entity relationship diagram.

Most physical data stores represent a single file or a single

database or table in the database. Additional physical data

stores may be added to represent temporary files or batches

necessitated by physical processes.

The name of a physical data store uses the following format:

• file or database implementation method : file, database, or table

name

• file, database, or table name : file or database implementation

method

MODULUS 11

The following procedure is used to assign a check digit to a key field:

STEP 1: Determine the size of the key field in digits.

2 4 1 3 5 = 5 digits

STEP 2: Number each digit location from right or left beginning with the number “2.”

2 4 1 3 5

6 5 4 3 2

STEP 3: Multiply each digit in the key field by its assigned location number.

2 X 6 = 12

4 X 5 = 20

1 X 4 = 4

3 X 3 = 9

5 X 2 = 10

STEP 4: Sum the products from step 3.

12 + 20 + 4 + 9 + 10 = 55

STEP 5: Divide the sum from step 4 by 11.

55/11 = 5 Remainder 0

STEP 6: If the remainder is less than 10, append the remainder digit to the key field. If

the remainder is equal to 10, append the character “X” to the key field.
