Projects are generally complex attempts to achieve something. However, a precise schedule model allows the project to be abridged into manageable groupings or phases. Project performance is reported and monitored when progress against these activities and milestones is recorded. The different types of activities are relevant to scheduling and forms of changing and crashing (accelerating) a schedule. This practice standard is organized in five main sections:

The development of a good schedule model is accomplished through the rational application of sound practices. Experience acquired over time helps to select proper responses to the design requirements for the schedule model. One of the key steps is to define the Project's Activities which is equal to create a list of activities that need to be implemented to complete the project, based on the WBS and expanded by the team responsible for the execution of the work. These activities should represent the expected sequence of the activities and represent the manner of how the work will occur. An activity is a measurable and discrete element (or block) of work that is a tangible element of the project scope. Reference!!!Activities are specific actions that are performed to produce the project deliverables. The characteristics of a well-defined activity include:
+
−
*Activity owner. Multiple resources may be required to accomplish the activity; however a single person is responsible and accountable for its performance. That individual should also report progress on the activity.
+
−
*Activity description. Activities describe the work that needs to be accomplished. As such, the description for each activity starts with a verb and contains a unique, specific object. Despite the fact that `pour concrete to the wall` may be descriptive of a task, the activity description needs to be more specific. Adjectives may be helpful to clarify uncertainties. Each activity description should be unique and leave no room for confusion, that is, it can be identified without ambiguity and it should be independent of the schedule presentation grouping or organization.
+
−
*Continuity of work activity. The work represented by an activity, once started, should be capable of proceeding to completion without interruption (except for naturally occurring nonwork periods in the calendar). When the work on an activity postponed or delayed, it is often beneficial for the activity to be split. This is noted by a single summary bar shown above the activities to reflect what is shown under that bar and coded to the appropriate group. Note that the start and finish dates reflect the early start date and the early finish date-not the late dates. Also the duration reflected on the summary bar matches the elapsed time from start to finish of the group activities. Some software programs accomplish this summarization automatically within the software. In doing so, the software rolls up the data according to specific rules and depicts it as a bar extending over the specific duration. Another example of a summary activity is an activity that can take longer than 2 or 3 update periods such as a procurement activity performed by someone outside the project and expected on the site at a particular date. The status of the work effort can not be incorporated in the schedule other than accounting for time until the event occurs.

The different types of activities are relevant to scheduling and forms of changing and crashing (accelerating) a schedule:

Contents

[edit] Resource-dependent activities

  • Duration can be changed.
  • The duration of the activity can be halved if the resources are doubled (experienced employees).
  • Examples: programming, digging drawing work
  • Speed up: add more people

[edit] Process-dependent activities

  • Activities where the duration is determined by a process that must be implemented to achieve the desired result
  • Characterized by that it can't be rushed
  • Examples: pregnancy, curing of concrete, training and education of employees
  • Speed up example: Difficult, in some cases through e.g. change of equipment

[edit] Procedure-dependent activities

  • Activities where a certain procedure must be followed
  • The uncertainty related to the outcome of the procedure.
  • Examples: steering committee meetings, consultation of stakeholders
  • Speed up example: Ebola and the change on regulation

[edit] Problem-dependent activities

  • Activities to solve a problem.
  • Innovation is paramount. Can be difficult to estimate the duration
  • Examples: design tasks, development, creative tasks
  • Speed up example: difficult, through intermediary deadlines or forcing an end - 'time boxing'
