𝗣𝗿𝗶𝗺𝗮𝘃𝗲𝗿𝗮 𝗣𝟲, 𝗱𝗮𝘁𝗲 𝗰𝗼𝗻𝘀𝘁𝗿𝗮𝗶𝗻𝘁𝘀 are used to specify when an activity should start or finish.
They help control the scheduling of activities by imposing restrictions based on specific dates.
Here are the main 𝗱𝗮𝘁𝗲 𝗰𝗼𝗻𝘀𝘁𝗿𝗮𝗶𝗻𝘁𝘀 𝗮𝘃𝗮𝗶𝗹𝗮𝗯𝗹𝗲 𝗶𝗻 𝗣𝗿𝗶𝗺𝗮𝘃𝗲𝗿𝗮 𝗣𝟲:
𝟭. 𝗦𝘁𝗮𝗿𝘁 𝗢𝗻 (𝗦):
Activities with a Start On constraint must start on a specific date specified by the user. This constraint locks the start date of the activity to the specified date.
𝟮. 𝗙𝗶𝗻𝗶𝘀𝗵 𝗢𝗻 (𝗙):
Activities with a Finish On constraint must finish on a specific date specified by the user. This constraint locks the finish date of the activity to the specified date.
𝟯. 𝗦𝘁𝗮𝗿𝘁 𝗢𝗻 𝗼𝗿 𝗔𝗳𝘁𝗲𝗿 (𝗦𝗔):
Activities with a Start On or After constraint must start on or after a specific date specified by the user. This constraint allows the activity to start later than the specified date but not earlier.
𝟰. 𝗙𝗶𝗻𝗶𝘀𝗵 𝗢𝗻 𝗼𝗿 𝗕𝗲𝗳𝗼𝗿𝗲 (𝗙𝗕):
Activities with a Finish On or Before constraint must finish on or before a specific date specified by the user. This constraint allows the activity to finish earlier than the specified date but not later.
𝟱. 𝗦𝘁𝗮𝗿𝘁 𝗢𝗻 𝗼𝗿 𝗕𝗲𝗳𝗼𝗿𝗲 (𝗦𝗕):
Activities with a Start On or Before constraint must start on or before a specific date specified by the user. This constraint allows the activity to start earlier than the specified date but not later.
𝟲. 𝗙𝗶𝗻𝗶𝘀𝗵 𝗢𝗻 𝗼𝗿 𝗔𝗳𝘁𝗲𝗿 (𝗙𝗔):
Activities with a Finish On or After constraint must finish on or after a specific date specified by the user. This constraint allows the activity to finish later than the specified date but not earlier.
𝟳. 𝗠𝘂𝘀𝘁 𝗦𝘁𝗮𝗿𝘁 𝗢𝗻 (𝗠𝗦):
Activities with a Must Start On constraint must start on a specific date specified by the user. If the activity cannot start on the specified date due to dependencies or resource constraints, the activity will be delayed until it can start.
𝟴. 𝗠𝘂𝘀𝘁 𝗙𝗶𝗻𝗶𝘀𝗵 𝗢𝗻 (𝗠𝗙):
Activities with a Must Finish On constraint must finish on a specific date specified by the user. If the activity cannot finish on the specified date due to dependencies or resource constraints, the activity will be delayed until it can finish.
These date constraints help project managers control the 𝘀𝗰𝗵𝗲𝗱𝘂𝗹𝗶𝗻𝗴 𝗼𝗳 𝗮𝗰𝘁𝗶𝘃𝗶𝘁𝗶𝗲𝘀 and ensure that they 𝗮𝗹𝗶𝗴𝗻 with project requirements and constraints.
However, it’s important to use date constraints judiciously and consider their impact on the overall project schedule. 𝗢𝘃𝗲𝗿𝘂𝘀𝗲 𝗼𝗳 𝗰𝗼𝗻𝘀𝘁𝗿𝗮𝗶𝗻𝘁𝘀 can lead to 𝗶𝗻𝗳𝗹𝗲𝘅𝗶𝗯𝗶𝗹𝗶𝘁𝘆 and 𝗶𝗻𝗮𝗰𝗰𝘂𝗿𝗮𝗰𝗶𝗲𝘀 in the schedule.
