Multi-tenant systems are a common pattern in enterprise software. Multi-tenant systems are designed to provide every tenant a dedicated share of a single system instance (Wikipedia). The key benefit of a multi tenant system is the immediacy of a new (logical) customer instance. In a sense, it's a bit like an apartment building: you don't need to build a new building for each new tenant, but rather house many tenants in a single building, aided by common infrastructure like hallways and shared plumbing.

With all of this data, the team ran statistical models to understand which of the many inputs collected actually impacted team effectiveness. Using over 35 different statistical models on hundreds of variables, they sought to identify factors that:

impacted multiple outcome metrics, both qualitative and quantitative
surfaced for different kinds of teams across the organization
showed consistent, robust statistical significance

BOSH is a tool for deploying software, packaged as BOSH releases, to VMs (virtual machines) in the cloud. BOSH will also monitor the software and recover from failures. Cloud Foundry relies on BOSH for deploying infrastructure.
