Distributed software teams face coordination challenges
Lack of awareness of evolving code dependencies
de Souza et al, 2007
Difficulty in maintaining coordination
Cheng et al, 2003

Need for communication
Software gets developed faster when people working on related code communicate with each other
Cataldo et al, 2006

Existing work on improving coordination
Collaboration features, such as extended instance messaging capabilities
e.g., Cheng et. al.
Expertise Recommendation Systems
e.g., Expertise Browser, EEL
Awareness tools
e.g., Palantir

Jazz and Jazz development data
A change set that is associated with a Work Item was delivered
An iteration plan with an initial deadline is created
A process rule: “All JUnit tests must be run before code is delivered” is added
Web client Rational Team Concert client Jazz development data stored in a Jazz repository

Software development governance (SDG)
Businesses need techniques for understanding the value provided by software development and delivery
Businesses need insights into the risks incurred through software development and delivery activities

Tempo
Addresses project scheduling risks
Allowing developers to express uncertainty in task estimates
Computes the probability that tasks given estimates that developers provide
