Sr Consultant BI Z Zdesign Center Of Excellence at a energy/utilities company with 10,001+ employees

Targeted stakeholder views have improved decision making and reduced architecture costs

BiZZdesign HoriZZon offers various valuable features. The best ones, besides those I have mentioned, include the AI space with the Diagram Describer and the Explorer functionality. I understand that BiZZdesign HoriZZon is also working on the Diagram Importer, which complements the Diagram Describer feature, providing full import and export functionality. Together with the contributor role and targeted stakeholder management, these features are essential. BiZZdesign HoriZZon introduced the Dynamic Solution Intent, enhancing the solution architecture by engaging diverse stakeholders with architectural artifacts. It supports the development of holistic solutions using reusable repository components. The deployment is hybrid cloud-based, specifically using Amazon Web Services as the cloud provider. I have also seen the implementation of return on investment features that contribute significantly to the organization’s overall effectiveness.

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.

Quotes from Members

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

Pros

"Return on investment is definitely there because we never had a single view of everything."

"BiZZdesign HoriZZon is a fantastic tool for enterprise architecture and capability mapping that helps map capabilities by turning complex engineering data into clear design documents, which is very important for cross-functional alignment and onboarding teams so they can onboard faster and it acts as a single source of truth."

"A big impact that BiZZdesign HoriZZon has on my organization is to improve the overview of the whole system for people around us."

"BiZZdesign HoriZZon stands out from other solutions on the market due to its uniqueness in conformance with the standard."

"One of the main advantages of this solution is that they have representation in the Open Group Forum, which means that any changes in ArchiMate are immediately implemented in BiZZdesign."

"The most valuable features are the application, portfolio, data, architectures, and modeling things."

"BiZZdesign helps us look at everything in our enterprise architecture through a business capability lens, rather than in EA language."

"I used BiZZdesign HoriZZon at two organizations. At Manchester Metropolitan University, I used it with a small team for architectural modeling of the student record system. We modeled teams, process objects, and their interactions with applications. We also used it to model a gradual rollout with plateaus showing migration over time. At the BBC, I used it to model software services for publishing content online. I showed key model views to senior stakeholders using Horizon, allowing them to modify and score applications and services."

More BiZZdesign HoriZZon pros

"The solution is pretty stable."

"We have seen ROI with this solution over the years that we have used it."

"The user interface is good. It's both clear and comprehensible. It's easy to work with."

"The main advantage of the solution and its most valuable aspect is the customization of the meta-model."

"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."

"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."

Cons

"Scalability is a bit of a problem for BiZZdesign. There is always a possibility it will failover."

"Since the accuracy is less, there is not much reliability, which means we need to cross-verify multiple times to ensure the data."

"We tested it, and we had support from BiZZdesign, including patches, but it just didn't do what we wanted."

"It should be more open to integrating with other existing tools. Although there has been progress in the past."

"There's room for improvement. When I finished using it over a year ago, I discussed implementing C4 notation with BiZZdesign HoriZZon.They've likely done this now, but I haven't seen it. Setting up interactive views for stakeholders to score services was a bit difficult."

"The frame, the labeling, the text, everything, they are scattered."

"Integration definitely needs improvement. There are some restrictions. We've seen that it doesn't integrate with everything we might expect."

"There is room for improvement in making it more seamless between the modeling and the analysis pieces. Sometimes you have to do some work in the backend to ensure that the HoriZZon portal really gets all of the information the way you want it. They are working on the seamlessness between what they call Enterprise Studio and HoriZZon."

More BiZZdesign HoriZZon cons

"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."

"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."

"This solution can be more user-friendly and easier to use, with better dashboards."

"Integration with all other software, like Microsoft, to facilitate an exchange, is not great."

"Some aspects of the user interface lack a common navigational or functional framework."

"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."

"The solution needs to better integrate with other products, like Microsoft."

"We are not happy with this product and are not planning to continue with it."

Pricing and Cost Advice

"First and foremost within the scope of improvement for the solution would be the cost. It's very costly..."

"[The] Orbus... pricing model was based on every single functionality having a price. The pricing was comparable but if we wanted to scale, it would have ended up being a lot more expensive. BiZZdesign gave us one price with all of the functionality, and we could scale as much as we needed."

"We were customers and bought licenses from them. We used their remote instance initially but upgraded to the on-device version due to lag. For pricing, we paid about 2200 pounds a year per seat for the client installation at an educational rate. I'm not sure about commercial rates. I managed to get a free copy at BBC since it was for evaluation purposes."

"The pricing model is slightly on the high side and could be more competitive for long-term partnerships."

"I haven't found any issues with the scalability and licensing parts that are access-related."

"If one is very cheap and ten is expensive, I rate the product price as a seven out of ten."

"The price is reasonable."

"In terms of this particular product usage, my clients currently only use per-user licenses."
