Continuous Integrations and Distributed Teams

Implementing Continuous Integrations

The practice of Continuous Integrations (CI) relies on certain pre-requisites being in place.

·        Version Control

Everything in your project must be checked in to a single version control
Repository

·        An Automated Build

You must be able to start your build from the command line. You can start off with a command-line program that tells you IDE to build your software and then runs your tests, or it can be complex collection of multistage build scripts that call one another.

·        Agreement of the Team

If people don’t adopt the discipline necessary for it to work, your attempts at continuous integration will not lead to the improvement in quality that you hoped for.

Automated testing is one very useful side effect of implementing CI.
With CI, we can detect Integration issues much earlier in the process
All the stakeholders including the business partners can see the small
Changes deployed into pre-production environment. This provides early
Feedback on the changes to software

Jenkins is one of the software that allows continuous integration.

Distributed Teams

Using continuous integrations with distributed teams is, in terms of process and technology, largely the same as in any other environment. However, the fact that the team is not sitting together in the same room – perhaps are not even working in different time zones does have an impact in some other areas.

· For Distributed teams within the same time zone, the continuous
Integration is much the same.

· For distributed teams in different time zones, there are more issues to deal with. If the team in USA breaks the build and goes home, this can be a serious handicap for the team in India. The process does not change bit
The importance of adhering to it is magnified.

· Some of the more powerful continuous integration servers have facilities
Such as centrally managed build farms and sophisticated authorization
Schemes that allow you to provide continuous integration as a centralized
Service to large and distributed teams.

· It is also worth considering to move to a distributed version control system such as Git that allows people to check in even when there is no link to the conventionally designated “master” server. In Git, contributions are made first by forming the repository of the project you wish to contribute to, making your changes and then asking the owners of the original repository to pull your changes if they are working all-right.

· Having a local version control system can also be an option in worst of
Circumstances. However it should be avoided as much as possible.

What are Important Roles in Scrum-Agile Teams?

The Primary Team roles in scrum are named as • Product Owner  • Scrum Master • Development Team Scrum Master, Product Owner, and Team are considered as people who are committed to the project while customers and executive management are considered as involved but not committed to the project. Scrum Teams are self-organizing and cross-functional. Self-organizing teams choose how best to accomplish their work, rather than being directed by others outside the team.  Cross-functional teams have all competencies needed to accomplish the work without depending on others not part of the team. The team model in Scrum is designed to optimize flexibility, creativity, and productivity. Scrum Teams deliver products iteratively and incrementally, maximizing opportunities for feedback. Incremental deliveries of “Done” product ensure a potentially useful version of working product is always available. All the roles are based on the concept of “S...
