I want to paint the living room before painting the dining room, although I could do it the other way round, tooĮarly critical path-derived schedules often reflected only on causal (logical) or discretionary (preferential) dependencies because the assumption was that resources would be available or could be made available.It is logically possible to paint four walls in a room simultaneously but there is only one painter.It is illogical to pour concrete before you dig the foundations of a building.It is impossible to edit a text before it is written.There are three kinds of dependencies with respect to the reason for the existence of dependency: It can be easily shown however, that this would only work if resource levelling is not used, because resource levelling can delay a successor activity (an activity, which shall be finished just-in-time) in such a way, that it will finish later than the start of its logical predecessor activity, thus not fulfilling the just-in-time requirement. Microsoft recommends to use SF dependency for just-in-time scheduling. SF is rarely used, and should generally be avoided. Ideally, the sequence of all activities will be defined in such a way that the start of every activity has a logical relationship from a predecessor and the finish of every activity has a logical relationship to a successor". If other types of relationships are used, they shall be used sparingly and with full understanding of how the relationships have been implemented in the scheduling software being used. Sometimes it is necessarily to overlap activities an option may be selected to use start-to-start (SS), finish-to-finish (FF) or start-to-finish (SF) relationships.Whenever possible, the FS logical relationship should be used. The Practice Standard for Scheduling recommends, that "Typically, each predecessor activity would finish prior to the start of its successor activity (or activities)(known as finish-to-start (FS) relationship). (New shift started) SF (Previous shift finished)įinish-to-start is considered a "natural dependency".A SF B means "activity A must start before activity B finishes" (or "B can't finish until A has started").(Project work started) SS (Project management activities started).A SS B means "activity A must start before activity B can start" (or "B can't start until A has started").(Last chapter written) FF (Entire book written).A FF B means "activity A must finish before activity B can finish" (or "B can't finish before A is finished").A FS B means "activity A must finish before activity B can begin" (or "B can't start until A has finished").There are four standard types of dependencies: 3 Advanced cases of activities dependencies.You’ll be able to send effortless email reminders to resources by exporting Gantt chart visuals as PDF attachments.Being a project manager, you can feel that you’re in control by setting global or project-level access controls.You get the full-featured collaborative work facility to invite clients or team members and assign tasks online.
