Planning system for structured engineering work

PHASI helps project-intensive teams plan around deliverables, work phases, timeline context, calculated completion and project discussions.

How PHASI models structured projects

A project in PHASI starts with what is being delivered. Teams can model assemblies, zones, assets, documents, packages, scopes, service deliverables, supplier packages or other project items.

Each item then moves through reusable work phases on a timeline. These phases can represent requirements, engineering, procurement, fabrication, construction, review, testing, approval, handover or any custom workflow step.

Because phase bars are attached to real project items, completion can be calculated from the model itself. PHASI uses category weights and completed relevant phases to create deliverable-based Percent of Completion instead of a detached manual percentage.

Core features

Project Structure

Build a clear structure of what is being delivered: assemblies, zones, documents, assets, packages, scopes or work items.

Phase Timeline

Plan execution with reusable work phases such as requirements, engineering, procurement, construction, manufacturing, review, testing or approval.

Percent of Completion

Measure progress from project structure, category weights and completed relevant phases.

Timeline Comments

Keep questions, decisions and replies attached to the exact item, phase, owner and date.

Percent of Completion Methodology

How PHASI calculates model-based progress

Percent of Completion in PHASI is calculated from the planning model: project structure, relevant phase bars, category weights and completed work. A completion value is not just a separate opinion field; it is derived from phases that actually exist for each deliverable or work item.

Teams define category weights for the project, such as Requirements, Engineering, Procurement, Construction, Manufacturing, Testing or Approval. The weight for each category is distributed across relevant phases in that category, then rolled up through items, parent items and the top-level project structure.

This keeps progress configurable, but grounded in the plan project controllers maintain. The more accurately the team maintains the structure and timeline, the more accurately PHASI reflects the project’s current state.

The planning model

  1. 1 Structure

    Define the deliverable structure

    Create the hierarchy of what belongs to the project: deliverables, components, modules, buildings, zones, documents, packages, assets, scopes or service items.

  2. 2 Phases

    Configure reusable work phases

    Create phase categories that describe how work moves from start to completion, such as requirements, engineering, procurement, construction, manufacturing, review, testing, approval or handover.

  3. 3 Timeline

    Schedule phases on the timeline

    Place phase bars on the timeline for each project item so teams can see when work is planned, where phases overlap and how the sequence develops.

  4. 4 Progress

    Track model-based completion

    Measure progress through relevant phase completion and project-specific category weights at item, parent item and project level.

Adapt to engineering and project-controls vocabularies

PHASI does not require one fixed industry vocabulary. A project item can be an assembly, zone, work package, document, asset, service item, supplier package, scope or maintenance asset. The team defines the vocabulary; PHASI provides the planning model.
