A task constraint in Project.net allows the start and finish date of a task to be set no later than, no earlier than, or on a specific date.
You may want a task to have both a start and a finish constraint. In many cases, Project.net supports these joint constraints directly. In addition, many constraint combinations can be supported through a combination of constraints and dependencies. This article talks about how to implement combined constraints in all of these ways, as well as how to arrange that tasks start and/or finish in between a pair of dates.
Tasks in Project.net have constraints that require that the start and/or finish date of a task be no later than, no earlier than, or on a specific date.
Constraints are not enforced at all for manual tasks, and for automatic tasks, they are only enforced when the workplan is rescheduled. See the article on Automatic Tasks for more details about how automatic tasks are scheduled in general.
This article talks about how constraints can be set, and how they can be visually identified in a workplan.
1. Setting Constraints
Project.net has two kinds of leaf tasks – manual and automatic.
Manual tasks are manually scheduled. They should be used when you want to explicitly set a task's start and finish dates and not allow it to be changed automatically by the scheduler based on changes to other tasks.
In this article, we're going to talk about how the duration and scheduled start and finish dates are tied to one another, and how changing any one of them affects the others.
1. Duration and Start & Finish Dates
Project.net has two kinds of leaf tasks – manual and automatic. Automatic tasks are automatically scheduled. They should be used when you want the project.net workplan scheduler to automatically set the start and finish dates of a task, based upon its work and duration, its constraints, and its dependencies on other tasks.
In New/View/Edit Task, the Dates section shows Calculated Scheduling if the workplan supports automatic tasks. And the task is then automatic, unless the user checks the checkbox to force it to be manually scheduled.
In this article, we're going to talk about how automatic tasks are scheduled by the scheduler.
Project.net, like Microsoft Project, supports 3 calculation types – fixed-work, fixed-duration, and fixed-units. In this article, we're going to talk about how they affect work and duration, and which one you should use.

1. Using Work & Duration Fields
It isn't long before even the best project plan is rendered obsolete by new realities. And in an environment of shared resources and common strategic goals, the impact can spread like a virus. To succeed, organizations must apply collaborative tools and practices that go beyond planning and bring enterprise-wide project execution to the forefront.
In a famous FedEx TV commercial, a lowly shipping clerk is on the phone getting the parameters of a critical project — namely, sending a very important package overnight to an impatient customer. After each instruction, he confidently responds, "I can do that! I can do that!" Then he hangs up the phone with a horrified look and asks himself, "How am I gonna do that?"
The Program and Portfolio Management Maturity Model is an effective tool for organizations to quickly decide what PPM improvements they should make to enhance their organizations' abilities to optimize investments, execute big changes and deliver value.
The Standish Group's "CHAOS Summary 2009" report shows a marked decrease in IT project success rates, with 32 percent of all projects succeeding. It's one thing to know that 68 percent of all IT projects don't succeed. But it's another to look across your company and realize you have no way of knowing which of your projects might be in the 68 percent bucket and which have the potential to be in the 32 percent bucket.
Project Portfolio Management is gaining respect for effecting successful project outcomes, creating a discipline of informed, confident decision-making and better stewardship over scarce resources.
