Users discuss how they are putting erwin’s data modeling, enterprise architecture, business process modeling, and data intelligences solutions to work
IT Central Station members using erwin solutions are realizing the benefits of enterprise modeling and data intelligence. This article highlights some specific use cases and the results they’re experiencing within the organizations.
Enterprise Architecture & Business Process Modeling with erwin Evolve
An enterprise architect uses erwin Evolve at an aerospace/defense firm with more than 10,000 employees. His team is “doing business process modeling and high-level strategic modeling with its capabilities.” Others in his company are using it for IT infrastructure, such as aligning requirements to system solutions.
For Matthieu G., a senior business process management architect at a pharma/biotech company with more than 5,000 employees, erwin Evolve was useful for enterprise architecture reference. As he put it, “We are describing our business process and we are trying to describe our data catalog. We are describing our complete applications assets, and we are interfacing to the CMDB of our providers.”
His team also is using the software to manage roadmaps in their main transformation programs. He added, “We have also linked it to our documentation repository, so we have a description of our data documents.” They have documented 200 business processes in this way. In particular, the tool helped them to design their qualification review, which is necessary in a pharmaceutical business.
erwin Evolve users are experiencing numerous benefits. According to the aerospace enterprise architect, “It’s helped us advance in our capabilities to perform model-based systems engineering, and also model-based enterprise architecture.”
This matters because, as he said, “By placing the data and the metadata into a model, which is what the tool does, you gain the abilities for linkages between different objects in the model, linkages that you cannot get on paper or with Visio or PowerPoint.” That is a huge differentiator for this user.
This user also noted, “I use the automatic diagramming features a lot. When one of erwin’s company reps showed that to me a couple of years ago, I was stunned. That saves hours of work in diagramming. That capability is something I have not seen in other suppliers’ tools.”
He further explained “that really helps too with when your data is up to date. The tool will then automatically generate the updated diagram based on the data, so you know it’s always the most current version. You can’t do that in things like Visio and PowerPoint. They’re static snapshots of a diagram at some point in time. This is live and dynamic.”
Data Modeling with erwin Data Modeler
He elaborated by saying, “We have an enterprise model being maintained and we have about 11 business-capability models being maintained. Examples of business capabilities would be finance, human resources, supply-chain, sales and marketing, and procurement. We maintain business domain models in addition to the enterprise model.”
Roshan H., an EDW architect/data modeler who uses erwin DM at Royal Bank of Canada, works on diverse platforms, including Microsoft SQL Server, Oracle, DB2, Teradata and NoSQL. After gathering requirements and mapping data on Excel, they start building the conceptual model and then the logical model with erwin DM.
He said, “When we have these data models built in the erwin DM, we generate the PDF data model diagrams and take it to the team (DBA, BSAs, QA and others) to explain the model diagram. Once everything is reviewed, then we go on to discuss the physical data model.”
“We use erwin DM to do all of the levels of analysis that a data architect does,” said Sharon A., a senior manager, data governance at an insurance company with over 500 employees. She added, “erwin DM does conceptual, logical and physical database or data structure capture and design, and creates a library of such things.
We do conceptual data modeling, which is very high-level and doesn’t have columns and tables. It’s more concepts that the business described to us in words. We can then use the graphic interface to create boxes that contain descriptions of things and connect things together. It helps us to do a scope statement at the beginning of a project to corral what the area is that the data is going to be using.”
Data Governance with erwin Data Intelligence
IT Central Station members are seeing benefits from using erwin Data Intelligence (erwin DI) for data governance use cases. For Rick D., a data architect at NAMM, a small healthcare company, erwin DI “enabled us to centralize a tremendous amount of data into a common standard, and uniform reporting has decreased report requests.”
As a medical company, they receive data from 17 different health plans. Before adopting erwin DI, they didn’t have a centralized data dictionary of their data. The benefit of data governance, as he saw it, was that “everybody in our organization knows what we are talking about. Whether it is an institutional claim, a professional claim, Blue Cross or Blue Shield, health plan payer, group titles, names, etc.”
A solution architect at a pharma/biotech company with more than 10,000 employees used erwin DI for metadata management, versioning of metadata and metadata mappings and automation. In his experience, applying governance to metadata and creating mappings has helped different stakeholders gain a good understanding of the data they use to do their work.
Sharon A. had a comparable use case. She said, “You can map the business understanding in your glossary back to your physical so you can see it both ways. With erwin DI, I can have a full library of physical data there or logical data sets, publish it out through the portal, and then the business can do self-service. The DBAs can use it for all different types of value-add from their side of the house. They have the ability to see particular aspects, such as RPII, and there are some neat reports which show that. They are able manage who can look at these different pieces of information.”
