【 Weak current College 】 project time management (2)

Milestone: note can be divided into levels, such as milestone milestone. In order to monitor project progress performance, set of checkpoints is also a form of the milestone.
Leading and lagging (LeadandLag): advance often rapid root into when you approach it.
3. the activities of the resource estimation
Note resources including equipment, raw materials and human resources. Once the activity definition and the sort is complete, the activities of the resources required and the number of types and resources are defined. Activities resource estimation of input is active inventory and activity properties, another input comes from the human resources management team formation process group of available resources, some organizations may have a resource pool, you can use the resources in the resource pool. Activities resource estimation and cost estimation process closely, since efficient resources often costs are very high.
Activities resource estimates results it is necessary to identify each activity uses the resources of the number of types and resources. In addition the resource breakdown structure is also an important output, this is mainly used for levels of raw material resources estimates.
The resource calendar is also an important resource estimation, output for different types of resources you can define different resource calendars.
4. the active duration estimates
Complete all the work is to determine the active duration. Many factors will influence the duration of the activity, such as the resources of the level of productivity, input the number of resources. Therefore the active duration estimate is a complex estimation process. Estimation methods can take parameters estimation, to compare estimates or three-point method for estimating, but accumulated enough data is still the recommended parameters estimation method for better precision.
Here it is necessary to pay attention to cost estimate is the active duration estimation of one input, instead of active resource estimation of input. Basic description of such a relationship between the activities of the resource estimation successively-> activities cost estimation-> active duration estimates.
5. the development schedule
Activities continued to estimate is completed you can start on the network map, calculate the critical path above to start the row of progress, by rush or quick follow-up on the progress of the compression, the analog or key chain method on resource assessment, taking into account the specific resource calendars to schedule can reach the final. So the Planner must consider the resource calendar.
Activities resource estimate direct follow-up activity list. Therefore the project scope statement is time management all other input, in addition to the activities of the resource estimate and schedule control. In the development of a schedule of when you need the following content:
What needs to be done on the project work of understanding (range specification)
Define activities (WBS, WBS dictionary and active listings)
Work order (activity sorting)
Need resources estimates (activity resource estimate)
Each active duration (active duration estimates)
Progress development is a comprehensive consideration of multiple factors, including stakeholder priorities, resource balancing, balancing the three factors and constraints, dependencies, and assumptions of the project, resources for other projects, relations and conflicts, etc.
In the development of the tools mentioned in the progress meter and technology: progress network analysis, critical path method, key chain, resource assessment, progress compression, PERT and what-if analysis, etc. Critical path is a network diagram, the longest path can be the shortest cycle is completed, on the critical path to float and float are zero. If you want to compress project progress must be compressed on the critical path, but to prevent the emergence of a critical path. Resource assessment and focus of critical chain method is in progress plan when to consider specific resource constraints. Critical path calculation determined first by pushing ES and EF, again based on backstepping determine LS and lF.
The total free float and float: the total float is valid on the entire path, there is a general floating currently active late-the earliest you can get LS1-ES1, total float does not affect the end time of the entire project. Free float is not to affect downstream get early start to have the free float floating, need to get up and down two to calculate LS1-EF0. takes note of the value of the total float is greater than or equal to the value of the free float. Note the float is can also be negative.
Rapid follow-up and progress made in the compresses rush is often used in two ways, but there is a difference between the two, rapid follow-up tend to adjust the Lead and Lag time, adjusted for sorting often increase the risk of the project. And catch the progress generally put more resources or overtime, so often is to increase the cost of the project.
Develop schedules have two important output, a schedule, the schedule by the bar chart, milestones and activities depend on the formation of the three superimposed. Another important output is progress benchmarks for progress benchmarks is late progress performance measurement and an important basis for progress tracking.
