Một quyết định đi trong giai đoạn phân bổ bắt đầu phần chính của giai đoạn dự án thực hiện. Sự bắt đầu của giai đoạn này báo hiệu sự bắt đầu để có cường độ gia tăng nỗ lực và chi phí. Quy hoạch, hành động bắt đầu. | Eight stages 23 loops within each stage. Primary feedback involves costs but should be costeffective if limited and therefore welcome. Secondary and tertiary feedback loops indicate more costly feedback to be avoided if possible. The execute stage A go decision in the allocate stage initiates the main body of the project the execute stage. The start of this stage signals the start of order-of-magnitude increases in effort and expenditure. The planning is over the action begins. During execution the essential process threat is that co-ordination and control procedures prove inadequate. A common perceived threat in the execute stage is the introduction of design changes but these may be earlier sources of uncertainty coming home to roost including opportunities that should have been spotted earlier to take full advantage of them. Consequent adjustments to production plans costs and payments to affected contractors ought to be based on an assessment of how project uncertainty is affected by the changes and the extent to which revised risk management plans are needed. For most projects repeated iteration will be necessary through the steps within the execute stage. Exceptionally loops back to earlier stages may be necessary. Big surprises including major opportunities missed earlier could take some aspects of the project right back to the concept stage or lead to a no-go decision including project abortion. Both nasty and pleasant surprises are realized sources of uncertainty from earlier stages that were not identified indicating a failure of the risk management process in earlier stages. The rationale for separate deliver review and support stages The project termination phase of Table involves three distinct aspects captured in the deliver review and support stages each encompassing different risk management concerns. The rationale for their separation and no further separation has the same form as the argument for separation of the design plan and allocate .
