Schedule Update

4. Problem Definition Requirements gathering is time consuming
Each new tool requires a new station controller
Each individual user will have different functionality the SC needs to provide
Requirements gathering is a time consuming process in software engineering, and it is no different for station controllers. SC developers have to produce an SC for each new manufacturing tool to be used in a Intel facility. Each tool has a user, and each user will need different functionality to use the tool efficiently.

5. Project Description
Goal: Help station controller developers gather requirements
SCST (Station Controller Survey Tool)
SC developers feed SCST questions
SCST produces executable for tool users
Tool users answer questions, sending results back to SC developers
CSCP (Customizable Station Controller Prototype)
Tool users manipulate a clone of real SC
The finished custom SC will be used by SC developers to provide the desired functionality

6. Design Methodologies SCST CSCP
We will use the classic Waterfall method
Reason:
Requirements well known
CSCP
Waterfall with Prototyping
Reasons:
Requirements may change (new SC under Development)
Highly GUI-centric program

7. Architecture Design Overview
SCST
Functional View
Logical View
Data View
CSCP

8. SCST Functional View Works like a Wizard Users step through questions
Functionality:
Forward
Back
Load
Save
Finish

9. SCST Logical View Parser QuestionList Saver QUI SCSTDocWriter
Reads input question file, creates QuestionList
QuestionList
Contains questions and answers
Saver
Writes questions and and answers for parser to read
QUI
Question User Interface (the “Wizard”)
SCSTDocWriter
Writes a “pretty” text file of answers for SC developers

10. SCST Data View Questions Radio Checkbox Text
Answer is one of the input choices
Checkbox
Each option is either selected or not
Text
Users enter a text response

11. CSCP Functional View

12. CSCP Logical View GUI TextFieldList MenuItemList DemoScript
Drag and Drop TextFields and MenuItems
TextFieldList
List of TextFields in Prototype
MenuItemList
List of MenuItems in Prototpye
DemoScript
Instructions to simulate real operation

13. CSCP Logical View (cont’d)
Reader
Reads files of saved prototypes
Saver
Writes the prototype to a file for later user
CSCPDocWriter
Writes a “pretty” text file to document the users custom prototype

14. CSCP Data View Prototype TextField MenuItem
Consists of TextFields and MenuItems
TextField
Has name, position, and size properties
MenuItem
Has name, and location properties

15. Structural and Physical Views
The tools each stand alone, so there is no interaction with the outside world
Physical
Same with the physical view, they run on a single computer

16. Research Languages: Issues Considered: Visual C++ Visual Basic Java 2
Drag and Drop
Possible web deployment
File I/O

17. Design Decisions Language: Java 2
Availability
Familiarity
Satisfied language requirements
Output text files in lieu of Word format
Separate components (SCST and CSCP)
Design as a stand-alone app, leave room for web implementation

18. Test Plan Unit testing System testing Usability testing
During implementation
System testing
After integration
Usability testing
After other tests

19. Schedule 1/15 Research Phase Complete 1/31 Architecture Complete
2/12 Design Phase 80%
3/5 SCST Impl. 10%
3/28 CSCP Impl. 5%
4/11 Testing 0%
