Milestones, assumption and task (MAT)

• Import functionality (Alpha)

• Adding Comments (Alpha)

• Parser for editing slide (Beta)

• Adding new Slide (Final)

• Adding/Deleting new presentation (Major value add) (Final)

• Testing

Milestone Assumption Tasks

Assumption• One person in team is sick all the time.

This was done to mitigate risk.• No one will work in holidays• Each one will share their knowledge with

team members.

Milestone Assumption Tasks

Task• To study the features of Mediawiki and share

this knowledge among team members

• Divide the components of Wikipres among different team members based on their expertise

• Integrate the work of team members and check in to Tortoise SVN.

Experiences – Cultural Differences

Experiences

Work Hard Party Harder

Experiences

Informal meeting helped in cordial relations among team members.

It not only helped in discussing the problems offline but also increased the productivity of team.

Experiences - Trips

Experiences

Sleepless nights but great achievements

Problems in project

• Because of assignments from other subjects it was difficult to distribute work equally

• Few functionalities needed to sit in pair and develop. (Eg: parser)

Learning and Take Away• Do risk analysis well in advance

• Pair programming is a healthier approach.

• Most critical module in project should be identified first

• Never be egoistic with team members especially when working in distributed environment.
