tectm vs MS Project and Primavera
Your program is a P&L in disguise. MS Project and Primavera draw the bars without knowing what anything costs. tectm's program is cost-loaded and tied to the budget, so a slip on the critical path is a margin number that day.
WHAT MS PROJECT IS FOR
MS Project and Primavera are scheduling tools, and Primavera in particular is the standard on large infrastructure for good reasons: depth of scheduling logic, resource levelling, and decades of planner familiarity.
If your question is purely "what is the sequence and what is the float", they answer it.
WHAT TECTM IS FOR
tectm runs a full critical-path program, with forward and backward pass, float, baselines and Excel import, and then does the thing a scheduling tool has no data for: it cost-loads it off the same budget the cost report reads.
That loading time-phases spend into planned value, and that phasing is the forecast. Move an activity and the forecast moves itself; nobody rebuilds a cash curve in Excel afterwards.
Dates resolve where the work is, so a Perth job stops being priced on Sydney time and a Queensland one stops inheriting a public holiday it never had.
Can you run both?
Usually as an import. If the client-facing program lives in Primavera, bring it in and cost-load it here; the schedule stays where the contract says it lives and the money question gets answered anyway.
The question that decides it
When an activity slips a fortnight, how long before you know what it did to the margin? If the answer is "at the next monthly report", that is the gap.
