SNET and FNLT — explicit constraints that flag instead of block.
In many PM tools, constraints silently force the schedule into impossible states or mysteriously prevent changes. In Consequent, constraints flag violations instead — you see the problem clearly and decide how to address it.
What is SNET?
SNET constrains when a task can begin. If set, the task won't be scheduled before this date — even if all dependencies are satisfied earlier.
Example
"Install solar panels" depends on "Roof completion" (which finishes March 10). But panels won't be delivered until March 20. Set SNET = March 20 on the installation task.
What is FNLT?
FNLT is a deadline. If the task's calculated finish date exceeds this date, Consequent highlights the violation — the cell turns red, and you can see immediately that action is needed.
Example
"Launch marketing campaign" has a contract deadline of April 1. Set FNLT = April 1. If dependencies push the calculated finish to April 5, you'll see a red flag — and know you need to find 4 days somewhere.
Transparency
When constraints block, they hide problems. You don't see that a deadline is missed — the tool just refuses to show you the real schedule. Flags make problems visible so you can address them.
Reality Reflection
The schedule should show what will happen, not what you wish would happen. A constraint violation is information — it tells you the current plan won't meet requirements.
Actionability
When you see a violation, you can decide: shorten durations, add resources, parallelize work, or renegotiate the deadline. The tool doesn't decide for you.
Some PM tools have a "Must Start On" or "Pin to Date" feature. In Consequent, you achieve this explicitly by setting both SNET and FNLT to the same date.
This makes your intent fully auditable: anyone reviewing the schedule sees exactly what you constrained and why.
Constraints are often abused when they hide logic. By using SNET and FNLT as visible, non-blocking flags, Consequent keeps the schedule honest and explainable.
The planner stays in control, while the tool provides immediate, visible warnings.
