Architecture repository has strengthened data‑driven decisions and supported risk‑aware planning

BiZZdesign HoriZZon needs to publish its integration scenarios and integration points with other digital transformation tools such as IT service management, risk management, asset management, customer service, and ERP. The company should first build the scenario and define its integration points in business and technology to make customers more confident about having a complete solution. Currently, there is a challenge with the company to offer transparent and documented integration. They offer five integration points at a fixed price, but other things come at additional costs. However, specific information about what those additional items are, what the scenarios entail, what the schemas are, what the workflows include, and what the application integration involves is not provided. The learning portal does not include integration documentation at a high level or in detail. The portal does have comprehensive resources explaining how to make their website, how to create dashboards, and how to publish EA content, which are clear. The high-end tool on the laptop is also explained in detail, covering elements, relations, and everything as standard.

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

"The tool's most valuable feature is that its collaboration part is very good."

"It's a good tool, my colleagues that are making use of it for application, business processes, or data modeling are very satisfied with it, they find it easy to use, and the graphical representation is simple but therefore efficient."

"BiZZdesign Architect separates model from views and has a quite extensive set of analytical stuff built in to be very useful in complex environments."

"We can derive some meaningful insights from whatever data that we have, which is the main thing."

"The powerful editing function in teamwork project-based, common or shared modeling, based on a powerful repository and knowledge sharing in a portal are the most valuable features. These are the most important features for me. I can add the integration of individual modeling notations like Archimate plus BPMN and DMN, and so on. We travel from one location to another and the tool allows us to keep track."

"The most valuable features of BiZZdesign HoriZZon include the diagrammatic representation of BPMN models, which I find good for modeling, and things such as capability maps."

"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."

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

More BiZZdesign HoriZZon pros

"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."

"The user interface is good. It's both clear and comprehensible."

"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."

"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."

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

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

Cons

"This tool is something of a beast - it takes a long time to learn, and it isn't possible for casual users and most architects. Unless a person spends 500 or 1,000 hours on the tool or does very concentrated sessions using all its functionalities, it's very difficult to master."

"It lacks capabilities with regard to infrastructure modeling."

"In HoriZZon, there are different matrices. For example, if I have 10 different matrices, then I need to create an aggregate view out of those 10 matrices somewhere, and that is where we have been struggling a bit."

"There is room for improvement in making it more seamless between the modeling and the analysis pieces."

"It takes a long time to learn and understand, which is a learning curve you have to go through, but once you know how it works, it's very nice to work with."

"The visibility of things and the user experience in HoriZZon are horrible."

"The automatic data collection and interface need improvement."

"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

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

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

"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."

"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."

"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."

"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."

"There needs to be more information at the outset about how to use the solution and how to deploy it."

Pricing and Cost Advice

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

"The price is reasonable."

"[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."

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

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

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

"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."

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