The Breakdown Structure (IWBS) is required to ensure

principles need to be followed throughout the project life cycle, with each
phase involving the
planning of the work for the next and execution phases, as well as execution of
the EVM deliverables for the current phase.

The referred
items and activities above will initially (at the beginning of each phase) be
based on the latest phase-gate approvals for budgets and time-frames, and on the
best information available. It

contracts are placed or work is allocated to the performing parties. The work
should be kept in summary or planning packages, rather than holding back the
EVM process until the most accurate information is available, as this will be
detrimental to the Project Control’s EVM.
