As answered by people managing Trello and PHASI.
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:
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.
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:
The PHASI Advantage
PHASI helps engineering teams answer four essential questions:
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.
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:
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.
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.
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.
