Effective lifecycle management improves with strong version control and deep integration needs

There is room for improvement in implementing features fully. The user interface is inconsistent and outdated. It appears that different departments or locations have implemented features differently, leading to inconsistency. There is a significant need for improved integration, particularly using OSLC for connecting with other tools like SAP ERP or ALM tools. The version control, while consistent, lacks flexibility regarding changes in CAD data and requires manual intervention for BOM management analysis.

Useful for creating build-outs and architecture views, but requires a publisher add-on for some detailed reports

I don't use the tool or know a lot. It is going to have some shortcomings. When it comes down to publishing, we just found out this week that they actually have a publisher add-on. So, what we were trying to publish was not giving a detailed report about the architecture, views, etc. I just wish they had sent these to UNICOM and contacted them about add-on features for the publishing part of the tool.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:

Pros

"The version control maintains consistent versions, which is beneficial."

"The strong point of Windchill is its close connection between the CAD structure and the bill of materials structure."

"I like how the product integrates with other technical solutions."

"It is useful for creating build-outs and architecture views and for publishing reports and stuff like that for different programs."

"It has good end-to-end metamodel interrelationships."

Cons

"I would not recommend doing business with PTC regardless of the product."

"There is room for improvement in implementing features fully."

"Some parts of the system are exclusive, so we can't work with them."

"They need to add reports that show the enterprise architecture perspectives, and the dashboards should be comfortable for the senior enterprise architects so that they can view the complete landscape."

"I don't use the tool or know a lot. It is going to have some shortcomings. When it comes down to publishing, we just found out this week that they actually have a publisher add-on. So, what we were trying to publish was not giving a detailed report about the architecture, views, etc. I just wish they had sent these to UNICOM and contacted them about add-on features for the publishing part of the tool."

Pricing and Cost Advice

"I rate PTC Windchill's pricing a seven out of ten since it is pricey."

"I don't remember the price. It is a different cost for just buying it, and then you have a maintenance cost, which you need to renew every year."

Overview

Manufacturers have never needed real-time information sharing, dynamic data visualization, and the ability to collaborate more than they do today. With easy, secure data access for multi-disciplinary and geographically-distributed teams, quality-focused processes, and a data driven approach to manufacturing, Windchill is elevating how product development gets done.

Windchill’s open architecture enables easy integration with other enterprise systems, including IoT, providing a solid foundation for a product-driven digital thread. PTC's PLM application provides comprehensive out-of-the-box functionality and highly configurable role and task-based apps. Expand self-service access of traceable product data to non-experts who don’t typically use PLM, while avoiding over-customization and complexity.
