Today we explain about the project calendar & resource calendar.
##########################################
1. Project Calendar
###############################
The project calendar is a division rule between working hours and non-working hours.
It is equivalent to continuing to subdivide the schedule planning, and can be distinguished from unavailable time periods according to working days, work shifts or available development time periods (in days or smaller units).
In schedule planning, even if we are based on the estimated activity duration, the current time + activity duration! = End time.
It is also necessary to distinguish which time is available, and those times are not available, in order to fully estimate the project end time.
###############################
1. Project Calendar Definition
In the project calendar, the available working days and work shifts in which progress activities can be carried out are specified .
The project calendar distinguishes between periods of time (in days or smaller time units) that can be used for progress activities and periods of time that are not available.
2. Note:
In a schedule model, it may be necessary to use more than one project calendar to prepare the project schedule, because some activities require different working hours.
There may be a need to update the project calendar.
2. Application fields of project calendar
Project calendar (6.5.1, 6.5.3, 6.6.1)
Progress area
Make a schedule
Control progress
3. Resource calendar background
1. Resource calendar definition
The resource calendar records the available time period of each project resource in the project .
2. Resource calendar associated documents
(1) Schedule management plan
Develop a reliable schedule based on a good understanding of the availability and time constraints of various resources (including time zones, working hours, vacation time, local holidays, maintenance plans, and working hours in other projects)
3. Resource calendar execution time
The resource calendar needs to be gradually detailed and updated throughout the project .
The resource calendar is the output of the resource acquisition process and is available at any time when the process is repeated.
4. Content of resource calendar (time resource)
During planning activities, potential available resource information (such as team resources, equipment and materials) is used to estimate resource availability.
1. The resource calendar identifies each specific resource
(1) Working days when available
(2) Shift
(3) Normal business hours
(4) Weekends and public holidays
2. Resource calendar properties
Specifies the team and physical resources identified during the project
(1) When is it available
(2) How long it can be used
This information can be established at the activity or project level, which takes into account
(3) Resource experience
(4) Skill level
(5) Different geographic locations
5. Application field / process of resource calendar
Resource calendar (see 6.1.3.1, 6.5.1.2, 6.6.1, 6.6.3, 7.1.1, 9.2.1, 9.3.1, 9.3.3, 9.4.1.2, 9.4.3.4, 11.5.1.2, 12.2. 3.5)
Progress area
Control progress
The resource calendar shows the availability of team and material resources.
Resource area
Construction team
The resource calendar defines when project team members can participate in team building activities and helps to illustrate the team's availability throughout the project.
Risk areas
Planning risk response
The resource calendar determines when potential resources are available for risk response.
6. Update the resource calendar field / process
Progress area
Control progress
Update resource calendars to reflect resource calendar changes due to resource optimization, schedule compression, and corrective or preventive actions.
Resource area
Construction team
Update the resource calendar to reflect the availability of project resources.
Procurement area
Implement Procurement
The resource calendar related to the schedule may need to be updated based on the availability of the seller.
