2. Contents Introduction Decision Process Groups Spreadsheet Features Review (evaluating the process)‏ Demonstration

3. Introduction Minimum requirements:  Implement a basic Excel  GUI interface  Open and Save  10 Formulas and 5 Graphs  Formatting

4. Introduction Work with 16 people with different skill and abilities Decide language and coding environment Divide up the work  Make groups to accomplish tasks Find ways to communicate and share work Create new features Overcome challenges

5. Decision Process Broke into three groups  Each group had one head person managing and dividing the work in the group  The three groups communicated and integrated work Decided language: Java Decided coding environment: Eclipse

6. Decision Process Communication means:  svn: contained the entire code for the project and any work done by a group member for the project  Google group: to communicate with group members  Lab period: to interact directly with other members and measure progress

7. Groups Broke up into 3 groups  GUI/Graphing  Algorithms/Inner Workings  Integration/Testing

8. Groups GUI/Graphing  Created the GUI interface  Added menu items  Included the formatting  Created graphs and charts

9. Groups Algorithms/Inner Workings  Implemented Formulas  Storage of values in cells  Worked on different features  Worked with GUI group for functionality

10. Groups Integration  Tested and debugged code  Integrated work from GUI and Algorithm group  Came up with install framework  Keeping track of the progress of the project

11. Features Graphing  Scatter plot  Bar Graph  Line Graph  Pie Chart  Y axis bar graph

12. Features Formulas  Sum  Average  Square root  Sine, cosine, tangent, arcsine, arccosine, arctangent  logarithm, natural log  Median, mode

13. Features Formulas  Max and min  Absolute value  Floor and ceiling  balance

14. Features Open, Save Alignment (left, right, center)‏ Italics, Bold Monkey Button

15. Review Testing/Integration:  Testing plans worked from the start Able to find problems/bugs Brought problems to the proper groups’ attention Iron out code

16. Review Testing / Integration  Having a separate group doing integration didn’t work well Communication issues Having to find out who to talk to Lack of communication

17. Review Algorithms  Original plan didn’t work Cell objects to reference another cell Use of vector[][] Difficulties in dependency and referencing

18. Review Algorithms  New plan Use tree map Map the location to the comparable cell

19. Review GUI  Original plan Using built in java classes to manage the cells Difficulty – java made it easy but restricts the number of actions on the cells we could do

20. Review GUI  New plan We created our own classes for columns and cells
