GM
IT/Business Architect at a financial services firm with 51-200 employees
Lots of valuable features, especially the metamodel customization
In terms of what could be improved, we did not take the whole package with all the modules, and I think that the integration with other platforms like Office could be better. The reverse engineering of the database is already there, but in the next release I would like to see some pilot supplied with the solution in order to address any database.

Unified data models have supported end‑to‑end lineage and governed multi‑layer architectures
Synchronization is vital since I experience multiple problems, such as mismatched models and manual DDL handling. Improving the synchronization between models and databases can enhance integration and mitigate weak implementations. Additionally, enhanced version control integration with tools like Git would facilitate better management of changes and provide greater control over the modeling process. Regarding pricing, SAP PowerDesigner is relatively high-cost compared to other tools, though its extensive capabilities justify the expense. While many freeware options exist, SAP PowerDesigner stands out as a robust tool that handles various aspects of data standardization, lineage tracking, and modeling efficiently. Although access can be limited to a select number of users, SAP PowerDesigner is worthy of its price tag given its performance compared to alternatives like Erwin or Oracle Database Designer.

Quotes from Members

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

Pros

"The user interface is good. It's both clear and comprehensible. It's easy to work with."
"There are a lot of features I find valuable, but I think that the metamodel customization is one of the best features that the solution offers."
"The solution is pretty stable."
"The main advantage of the solution and its most valuable aspect is the customization of the meta-model."
"We have seen ROI with this solution over the years that we have used it."
"The System Architect Product has greatly assisted the corporate strategic planning process in two areas: the simulation of scenarios for Enterprise Transformation Projects and providing a global view of Enterprise Capabilities and Functional Gaps."
"What I appreciate best about SAP PowerDesigner is that it is a very detailed and comprehensive tool."
"I like the connectivity or the lineage between the models and usability."
"The physical database model is definitely the most valuable feature because it describes normalization exactly the way you understand the data, and it deploys it perfectly with open source systems."
"The most valuable feature is that it is a very fast reverse engineering process. It does a very expansive comparison."
"In summary, this product gives you all of the features that a modeler would require to produce both logical and physical data models."
"SAP PowerDesigner enhances the clarity of our data management significantly, as around 80% of data can be searched quickly and maintained in our SAP systems."
"The main valuable features are the logical and physical data modeling capabilities, and our main purpose is to keep the data model in a repository and then be able to generate DDL files for Oracle."
"SAP PowerDesigner stands out as a robust tool that handles various aspects of data standardization, lineage tracking, and modeling efficiently."
 

Cons

"It was sold separately and it is not very easy for somebody who wants to use the solution for modeling to think that you have to select specific modules in order to use the product."
"This solution can be more user-friendly and easier to use, with better dashboards."
"There needs to be more information at the outset about how to use the solution and how to deploy it. The deployment process needs improvement."
"Integration with all other software, like Microsoft, to facilitate an exchange, is not great."
"The solution needs to better integrate with other products, like Microsoft."
"The reverse engineering of the database is already there, but in the next release I would like to see some pilot supplied with the solution in order to address any database."
"We are not happy with this product and are not planning to continue with it."
"Some aspects of the user interface lack a common navigational or functional framework."
"Better support for integration with open-source technologies is needed. For example, I try to use open-source databases such as Postgres and MySQL instead of Microsoft, DB2, or Oracle, however, I think it's lacking in capability from the tool to the database."
"One issue is the cost, as it is a high-priced tool coming from SAP."
"In terms of improvement, the pricing is a bit high."
"SAP PowerDesigner can improve the ease of use. It is not the best tool on the market because it is tough to navigate and use. A beginner would not be able to use it well, it requires some experience. If the solution was more user-friendly it would be able to be used by more audiences. I do not think many people are aware of this solution and they should use it."
"Regarding improvements, I suggest enhancing the connection between objects in process and data models. It's crucial to define the structure of objects, especially when dealing with standard frameworks like VMM. There should be better visualization of arrows between BPM and data modeling objects, specifying their structure and impact. For future versions, a feature similar to Bizagi, allowing users to see forms or SQL representations of objects, would be valuable for demonstrating and presenting project details to stakeholders."
"Although the presentation for viewing the models is good, I think it could be better."
"I have found the solution not easy to use. When publishing you have to download the HTML, make adjustments against the updated HTML, convert it to HTML, then finally paste the HTML. There is not an on-the-fly function available to bypass the step-by-step converting process that other solutions have."
"SAP PowerDesigner is not a product that's really actively developed anymore in the sense that the user interface is outdated."
 

Pricing and Cost Advice

Information not available
"I bought the software outright and do not pay a licensing fee."
"SAP PowerDesigner is cheaper than eriwin."
"I would like SAP to prove free licenses to professionals that are using the solution. The free version is limited."
"The price of the solution is low."
"The ROI has been 43%."
"The pricing varies based on functionality and users."
"Regarding costs, SAP PowerDesigner is pricey, as I've heard from my team manager, which is why the company has been thinking of bringing another solution on board."
"When you purchase the license for SAP PowerDesigner, you have to buy one year of support. The tool is worth the money."
