Introduction

Minimum requirements: Implement a basic ExcelGUI interfaceOpen and Save10 Formulas and 5 GraphsFormatting

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

Decision Process

Broke into three groupsEach group had one head person managing

and dividing the work in the groupThe three groups communicated and

integrated work Decided language: Java Decided coding environment: Eclipse

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

Groups

Broke up into 3 groupsGUI/GraphingAlgorithms/Inner WorkingsIntegration/Testing

Review

Testing/Integration:Testing plans worked from the start

Able to find problems/bugs Brought problems to the proper groups’ attention Iron out code

Review

Testing / IntegrationHaving a separate group doing integration

didn’t work well Communication issues Having to find out who to talk to Lack of communication

Review

AlgorithmsOriginal plan didn’t work

Cell objects to reference another cell Use of vector[][] Difficulties in dependency and referencing

Review

AlgorithmsNew plan

Use tree map Map the location to the comparable cell

Review

GUIOriginal 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

Review

GUINew plan

We created our own classes for columns and cells

Demonstration

Time to show the real deal
