Critical path analysis identifies the most efficient and cost effective way of completing a complex project. The various activities which together will make up the project are identified, and the order of these activities are identified. Then, the duration of each activity is estimated and these factors are then arranged as a network or graph, showing the whole project from start to finish, and showing which tasks can happen at the same time. The sequence of tasks which have to be done one after another with no gaps in between is called the Critical Path.

Key outputs in this phase are the Projects Requirements definition, the capability and capacity assessment, project delivery strategy and the Project Management plan. The role of the construction/ project manager in this phase is, once project authorized, it is the project manager’s responsibility to implement the project. In terms of the Project Requirements Definition the, the project manager refines and details the project authorization and details what the project is required to accomplish in terms of the products/services the project will deliver and the scope of work that needs to be done. The project manager must provide project team members, corporate sponsors, and other stakeholders with a common understanding of what the project is all about, and is the authoritative reference document that defines the project.

The project will follow a series of phases during production. Each phase will reflect a goal in achieving a particular task and also the resources needed to

(TCO A) Which step of the project life cycle produces all of the project deliverables?

The first step will be to look at the goals of the project, and align them with the mission of the company. Systematically, the project will be broken into phases: Planning, Organizing, Staffing, Directing, Coordinating, Budgeting, Evaluating, and Reporting. Each phase will be further broken down into tasks and placed into a work breakdown structure. From this view, one is able to see the entire project duration, critical path, and milestones. The Planning phase is integral in any project. This phase of the project defines project objectives, mission, goals, and approach. In addition, outlining key elements of the project is critical: performance expectations, risks analysis, and contingency plans. However, after completion

In almost every business, project management is critically important. The critical path method (CPM) will provide a timeline for the project manager for when tasks should be completed. In addition, providing a deadline and the negative effects it will have on the following successors if not completed on time. These many task are interdepended. Therefore, the CPM provides the start and finishes times of the tasks, and identifies the few tasks on the critical path that the project manager should observe to determine which task needs the most attention. Already discovering and incorporating the details the task or assignments may require, CPM calculates all task times, which can be measured in hours, days, weeks, and months. For any unintended manually input errors, a warning message will be provided. Including an automatic successor generator, task numbering comment, and data validation, makes it easier on the project manager.

To better illustrate this concept figure 2 depicts the subtasks identified as Milestones. The project management has estimated the time required to complete the 1st phase of the project (Project Preparation) would require 10 days. Completion of the phase is signaled by the development of the Statement Of Works. The project management team could measure the performance of the project resources or team members by comparing the actual time required to complete the Milestone against the estimated time to complete the Milestone.

The project life cycle consists of the conceptualization phase, the planning phase, the execution phase, and the termination phase.

(Project definition: Planned set of interrelated tasks to be executed over a fixed period and within certain cost and other limitations)

Specific plans and projects. Scheduling is concerned about the implementation of activities necessary to achieve the laid down plans. The function of control is to institute a mechanism that can trigger a warning signal if actual performance is deviating (in terms of time, cost and some other measures of effectiveness) from the plan. If such a deviation is unacceptable to the concerned manager, he will be required to take corrective action to bring performance in conformity with the plans. The PERT and

In the define phase proposals are formulated, estimated and tested for feasibility. The results will be presented to the senior management in order to receive a "go" for the project which often is in the form of a contract.

In this stage, whatever comes out from plan phase get executed and the project work gets complete. Most of the time and depend on the project type, this is the longest

The nature and scope of a project is determined at the initiation stage. This involves analyzing the business needs, developing goals, budgets, tasks, deliverables, and the stakeholder analysis. The project planning stage determines the planning team, develops the scope, and identifies work breakdown structure and activities that will be needed to complete deliverables. The planning stage also estimates time and cost activities, develop schedule and risk plan, and gain formal approval for work to begin. The executing stage involves all processes used to meet the project requirement and involves managing people and resources. The process that entails the identification of potential problems and

c After the acceptance of all stakeholders is achieved, actual growth begins and a project management methodology needs to be selected based on the major areas seeking improvement. A project tracking and monitoring system has to be in place for improved estimation of project life-cycle.

This is the phase where the requirements are noted, feedback regarding requirements are obtained from users
