Critical Path Modelingv4.12.0 · April 2025

fastProject

An add-in to Microsoft Project and Excel that enables teams to plan, track, and accelerate projects using FTTM methodology. Continuously refined through client feedback since its introduction in 1989. Now in version 4.12.

Featured: Wigglechart™

The Wigglechart is lateralworks' proprietary schedule visualization — a diagonal/vertical chart that plots schedule acceleration over time. At a glance, you can see whether a project is pulling in, holding steady, or slipping. No other tool shows this.

Schedule Trend · Weeks

Wigglechart™

Proprietary schedule visualization that shows acceleration trends over time. The fastest way to see if your project is closing the gap — or falling behind.

Macro-Micro Roll-up

Connect high-level macro plans to detailed micro schedules across multiple projects and teams. One integrated view of a program that could span 50,000+ tasks.

Refresh Planning

The weekly cadence that makes FTTM real. Update actuals, decompose near-term tasks, pull-in the schedule. The habit that changes project behavior permanently.

FTTM Inspector

Diagnose schedule quality issues automatically. Finds common CPM mistakes before they cause missed milestones — the Analyzer that teaches teams to plan correctly.

Portfolio Dashboard

See all active projects in one view. Track relative schedule health, identify which programs need attention, allocate resources to the highest-value work.

Doneness Generator

Forces teams to define completion criteria before planning begins. The discipline that eliminates scope ambiguity and late-stage scope creep.

Decision ModelingActive · AHP-based

fastDecision

A structured decision modeling tool built on Analytic Hierarchy Process (AHP), implemented as a Microsoft Excel add-in. Enables groups to reach agreement faster and more effectively on complex, multi-criteria decisions.

Learn fastDecision →

How it works

01Define objectives hierarchy

02Weight criteria through pairwise comparison

03Score alternatives against criteria

04Generate priority ranking with rationale

05Build group consensus around the model

AHP Decision Engine

Based on the Analytic Hierarchy Process — a mathematically rigorous method for prioritizing complex options across multiple weighted criteria.

Group Consensus Tools

Facilitates multi-participant decision sessions. Surfaces hidden disagreements, quantifies divergence, and builds buy-in through transparent modeling.

Objectives Hierarchy

Structures decision criteria from strategic goals down to measurable attributes. Ensures decisions align with actual business objectives, not just stated preferences.

Portfolio Scoring

Apply decision modeling to entire project portfolios. Score and rank competing programs against weighted criteria to allocate resources rationally.

Cost-Benefit Curves

Generate visual curves showing the optimal combination of alternatives. Spot the point where additional investment stops producing proportional value.

Zero-Based Budgeting

Apply structured decision modeling to budget allocation decisions. Justify every dollar against explicit objectives rather than historical precedent.

Business Case ModelingActive · Excel-based

fastROI

A flexible business case modeling tool built on Excel. Quantifies the cost of delay and models trade-offs — so teams know exactly what a schedule slip costs in profit terms, and what accelerating it is worth.

Learn fastROI →

The cost of delay, quantified

"One project team was unable to close a 10-month schedule gap. They modeled the trade-off: a 2% hit to COGS costing $250M — versus a 12-month pull-in worth $500M. The decision was accelerated by more than a year."

— FTTM System, lateralworks research

Cost of Delay Modeling

Quantify what every day of schedule slip costs in lost profit. The metric that transforms "we're three weeks late" into a business decision with a dollar figure attached.

Trade-off Analysis

Model the financial impact of product and resource decisions. Should you increase headcount? Change the technical approach? fastROI shows the numbers.

Schedule-Finance Integration

Connect project schedule data directly to financial projections. When the schedule moves, the business case updates automatically.

Scenario Modeling

Compare alternative execution strategies side-by-side. Identify which path maximizes NPV, minimizes risk, or hits the target market window.
