Questions & Answers

As answered by people managing PHASI and Redmine.

What makes your product unique?

PHASI's answer

PHASI – A Product-Oriented Approach to Engineering Project Management

PHASI stands out through its structure- and phase-based approach to complex Engineering-to-Order (ETO) projects, custom machinery, and industrial equipment manufacturing.

Unlike traditional task-based project management tools, PHASI connects the Product Breakdown Structure (PBS) with Work Breakdown Structure (WBS) activities in a unified, interactive planning environment.

Key Differentiators:

  • Product-Oriented Planning – Organize projects around actual products, assemblies, and components instead of disconnected task lists.
  • Integrated PBS and WBS – Assign relevant work phases directly to product elements while maintaining a consistent project structure.
  • Interactive Phase-Based Scheduling – Create, move, and resize work phases directly on a visual timeline.
  • Calculated Percent of Completion (PoC) – Automatically calculate project progress based on completed work phases and configurable category weights, reducing reliance on subjective estimates.
  • Hierarchical Progress Tracking – Track calculated completion from individual components through assemblies to the entire project.
  • Flexible WBS Work Layers – View engineering, procurement, manufacturing, assembly, and testing activities without restructuring the product hierarchy.
  • Contextual Collaboration – Keep project discussions and working hours connected to relevant project activities.

What makes PHASI different?

PHASI connects what is being built, what work needs to be completed, when it is scheduled, and how much of the project is finished – all within one specialized planning environment.

Visitors can also try PHASI's interactive planning interface directly at phasi.app, without registration.

Why should a person choose your product over its competitors?

PHASI's answer

PHASI is specifically designed for engineering and manufacturing companies managing complex Engineering-to-Order (ETO) projects, custom machinery, and industrial equipment manufacturing.

Unlike general-purpose project management tools that primarily focus on tasks and deadlines, PHASI provides a product-oriented planning approach that connects technical product structures, work phases, schedules, and project progress in one environment.

Key Reasons to Choose PHASI:

  • Built for Engineering-to-Order Projects – Designed around the requirements of complex technical projects rather than generic task management.
  • Product-Oriented Project Planning – Structure projects around machines, assemblies, and components, ensuring that planned activities remain connected to what is actually being built.
  • Integrated PBS and WBS – Combine product structures with relevant work phases without maintaining separate, disconnected planning structures.
  • Interactive Timeline Planning – Create, move, and resize work phases directly on a visual timeline, making project scheduling intuitive and flexible.
  • Calculated Project Progress – Automatically calculate Percent of Completion (PoC) using completed work phases and configurable category weights instead of relying exclusively on subjective progress estimates.
  • Clear Project Readiness Visibility – Monitor calculated completion at component, assembly, and overall project levels.
  • Flexible Planning Across Disciplines – Coordinate engineering, procurement, manufacturing, assembly, software development, and testing within a consistent product structure.
  • Contextual Team Collaboration – Keep discussions, project information, and working hours connected to relevant project activities.

The PHASI Advantage

PHASI helps engineering teams answer four essential questions:

  • What are we building?
  • What work needs to be completed?
  • When is each work phase scheduled?
  • How much of the product and project is complete?

By connecting these aspects in a single planning environment, PHASI provides a structured and transparent approach to managing complex engineering projects.

Try Before You Decide

PHASI offers an interactive demonstration directly on its website, allowing visitors to experience its planning approach without registration or software installation.

How would you describe the primary audience of your product?

PHASI's answer

PHASI – Designed for Engineering and Manufacturing Professionals

PHASI is primarily designed for engineering and manufacturing companies managing complex technical projects, particularly in Engineering-to-Order (ETO), custom machinery, special-purpose machine building, and industrial equipment manufacturing.

The platform is suitable for small, medium-sized, and large organizations that require structured, product-oriented project planning and transparent progress tracking.

Primary Target Audience:

  • Project Managers – Plan, coordinate, and monitor complex engineering projects, schedules, and project progress.
  • Engineering Managers – Oversee technical activities, product structures, deliverables, and completion status.
  • Mechanical and Electrical Engineers – Plan and track engineering work phases associated with specific components and assemblies.
  • Production and Manufacturing Planners – Coordinate manufacturing, assembly, and testing activities.
  • Procurement Teams – Manage procurement phases linked to product components and project schedules.
  • Technical Project Coordinators – Monitor work phases, timelines, and calculated Percent of Completion (PoC).
  • Operations and Project Management Leadership – Gain visibility into project readiness across components, assemblies, and entire projects.

Ideal Use Cases:

PHASI is particularly valuable for companies where engineering, procurement, manufacturing, and assembly activities must be coordinated around a shared product structure.

By connecting Product Breakdown Structures (PBS) with Work Breakdown Structure (WBS) activities, PHASI helps cross-functional engineering teams plan technical projects and maintain a consistent overview of schedules and progress.

What's the story behind your product?

PHASI's answer

PHASI was born from many years of hands-on engineering experience and a problem I encountered repeatedly in real-world projects.

Throughout my career as a design and development engineer, as well as leading engineering teams and complex technical projects, I experienced firsthand the challenges of planning and managing Engineering-to-Order (ETO) projects.

One particular challenge stood out: the lack of suitable software that effectively connects the Product Breakdown Structure (PBS) with the Work Breakdown Structure (WBS).

In engineering projects, what needs to be done is directly related to what is being built. Yet traditional project management tools often treat product structures and work activities as separate elements. This disconnect makes planning, coordination, and progress tracking unnecessarily complicated, especially in custom machinery and industrial equipment manufacturing.

After years of working with these limitations, I decided to develop the solution I had been looking for myself.

That is how PHASI was created.

The central idea was simple: bring product structures, work phases, schedules, and calculated project progress together in one intuitive planning environment.

PHASI is the result of extensive practical experience in engineering, product development, team leadership, and technical project management. It was developed to address real challenges faced by engineering teams, providing a structured, product-oriented approach to planning and managing complex technical projects.

PHASI was built from engineering experience, for engineering teams.

Which are the primary technologies used for building your product?

PHASI's answer

PHASI is built with TypeScript, React, and Vite on the frontend, and Node.js with Express on the backend. It uses PostgreSQL for data storage, Redis and WebSockets for real-time updates, and Docker, Caddy, and Cloudflare for deployment and HTTPS delivery.
