Tool Styles for Architecture

#architecture #clarity #velocity #direction #enterprise #modeling

When doing enterprise architecture as well as systems engineering (or system architecture in detail) the question arises if there can be one meta model like Archimate and one tool that does it all.

That means, supporting the strategic portfolio level (comparable to city planning) as well as the development-oriented system level (architecture for one building at a time).

Roles vs Tool Styles

A very important requirement if talking about ‘enterprise’ is easy access to the captured landscape and its building blocks if for business products, applications, data, or technology as well as blueprints, planned architectures, and governance. This access must be provided for a range of users comprised by many people in the enterprise very probably having various roles and skills.

Since all this architectural information shall not only be consumed but also improved and maintained in a distributed fashion, it becomes clear that a tool focusing on diagram-first modeling style cannot be the answer no matter if based on UML, SysML, Archimate, or any other formal modeling language. The reason is that most of the users are not able to model and only a fraction can be taught due to the costs. Mostly, the focus lies on roles already having a certain skill set you can easily build upon, i.e., mostly roles matching the word ‘architect’. Prominent examples of such expert tools are MagicDraw (Cameo) by No Magic (now Dassault Systèmes), ARIS Architect by Software AG, Adonis by BOC, Innovator by MID, Enterprise Architect by Sparx, and others. But, as we will see, any of these can be part of your overall story.

Since the average user needs a tool that makes live easier and not harder, most EA tool vendors have focused on an approach that is data-first ERP style – typically providing web-based access to collected portfolio information (products, applications, business objects, technologies, and such). That information is presented as profiles or sheets like for each application which can also be updated via data forms. Tools like Alfabet (planningIT) by Software AG, LeanIX by LeanIX, LUY by iteratec, ADOIT by BOC, and others follow this path. From the captured data, they automatically produce dynamic graphical or tabular reports. Some of these tools also support Archimate ranging from basic import over addition to their own metamodels to own metamodels based on Archimate.

But why do EA tools always provide more than Archimate provides? This is because many important aspects in daily life are missing in Archimate like roles and permissions, multi-tenancy, life cycle information (planned, active, deactivated; generally state per date interval), portfolio planning capabilities (as-is, plan, to-be; the later with alternatives), tool integration features (requirements, publication, test management), and a lot more.

Scaled Architecture

On the other hand, the last decade has shown, that focusing only on the strategic portfolio level ignoring the reality on the ground easily leads to the ivory-tower syndrome producing badly accepted plans to change the IT landscape.

In order to avoid this, it is important to couple portfolio data with refined software and hardware architectures. The portfolio acts as the common structure and its content had better reflect the software and hardware inside (compare with reporting). And that’s where the above mentioned architects come into play again. They can bridge this gap by drilling down deeper to system architecture level and even further.

In that case, diagram-first modeling style tools for experts are more appropriate. As mentioned above, these are typically based on UML, SysML, Archimate, another modeling language, or even a combination of those. Modeling tools supporting Archimate as a dialect can make integration with enterprise architecture tools that are also supporting Archimate a little easier.


Being able to address both worlds is an important issue and not an easy task. Common meta models may help, but are not a must. More important is the ability to map high-level enterprise architecture blocks to medium-level system architecture content and that in turn to low-level system design content which can also partly be reverse engineered directly from running systems.

There are also tools that address both tool styles like ADOIT or upcoming versions of Bpanda that might be helpful, too. Let’s call it hybrid data-diagram style. Again, it is not a must, especially if different tools are already set in the organization and shall be integrated. The options are ranging from built-in integration features like export/import capabilities to separate integration tools like Smartfacts which provides a portal merging data from different tools via OSLC or classic synchronization.

Executive Summary: Data Strategy 2.0

#architecture #clarity #velocity #direction 

In my last post Executive Summary: Strategic Data Science, I have summarized what Data Science is and what it consist of. Moreover, you need to deploy a strategy that helps you manage transformation to a data-driven business.

Today, you will see that a strategy for data science can be handled just like any data strategy. And if you already have a data strategy deployed, e.g. as part of your governance or architecture initiative, then you will see why and where it is affected.

As written in Executive Summary on EA Maturity, having a map knowing where you are and where you want to go to helps a lot in finding a way.


If you are working with maturity models, you typically do this on a yearly basis. For chosen capabilities you identify current vs target maturity e.g. ranked from level 1 to 5.

The first thing you need to understand is that introducing data science for the first time reduces your overall maturity at once. Why is that?

Maturity is measured in terms of capabilities. And if you take a look into those capabilities you will find that you need to adapt them. There typically are a dozen or so like vision, objectives, people, processes, policies, master data management, business intelligence, big data analytics, data quality, data modeling, data asset planning, data integration, and metadata management.

I will pick only a few as examples to make things clear. Let’s pick vision, people, and technology.

Selected Capabilities for Explaining Maturity of Data Strategy


Say you have a vision like: “Providing customer care that is so satisfying, that every customer comes back to us with a smile”. That’s a very strong statement, but how about: “Keeping every customer satisfied by solving all problems before complaining”. Wow, even stronger. It is possible because Data Science allows you to predict what others can’t.


Probably, you already have a data architect. But, the classic data architect focuses on architecture, technology, and governance issues. This is OK, but you also need some data advisor focusing on unseen solutions for the business. Someone telling you to combine customer data with product usage data increasing your sales. And perhaps even telling you from which of your precious data you can create completely new data-driven products you can sell.


Probably, you also have an inventory telling you which data sources are used in your applications. Adding Data Science as rapidly growing discipline to the equation, you may find that you will have to revise your technology portfolio. It is rapidly growing and changing and, therefore, needs to be governed to a certain amount (freedom vs standardization).

Following list shows selected technologies that are most often used in Data Science (ranked from left to right).

  • Programming Languages: SQL, Python, R
  • Relational Databases: MySQL, MS SQL Server, PostgreSQL
  • Big data platforms: Spark, Hive, MongoDB
  • Spreadsheets, BI, Reporting: Excel, Power BI, QlikView

Moreover, there is a shift in who is actually using these technologies like Leadership, Finance, Sales, and Marketing. And more often without dedicated enterprise applications because data analysis is very dynamic and has a lot of try and error to it.


From these view capabilities out of a dozen+ it has become clear that Data Science Strategy easily fits into an overall Data Strategy. There is no need to reinvent the wheel. Instead, adapt your existing or favorite Data Strategy to incorparate Data Science.

Executive Summary: Strategic Data Science

#architecture #clarity #velocity #direction #data

If you as C-level are already using or plan to use data science you probably pursue the goal to increase your market share by making predictions that others can’t. You might think that there is no need for strategic management of data science. Actually, that’s as far from the truth as it can get. But, why is that? It is because there may be a lot of complexity indicated by the figure below and discussed in the following.

The Flower of Complexity


First, let’s take a look into the definition

Data science is an inter-disciplinary field that uses scientific methods, processes, algorithms and systems to extract knowledge and insights from many structural and unstructured data.

source: wikipedia

There are a lot of keywords in this rather short definition that should raise your eyebrows: inter-disciplinary, methods, processes, algorithms, systems, many.

Basic Method

Now, let’s pick a keyword from above and dig deeper e.g. recall the basic scientific method:

  1. Find a question
  2. Collect data
  3. Prepare data for analysis
  4. Create model
  5. Evaluate model
  6. Deploy model

Doesn’t sound overly complex, but let’s finally deep dive. Which of those phases do you think is responsible for most of the effort spent? It is the step that roughly amounts to 80% of the overall process! There are even several synonyms for it like data munging, data wrangling, and data cleaning or cleansing. You guessed right, it is phase three. Its complexity is mainly driven by the number of different data sources, the number and complexity of involved data structures, and sometimes also mixed with unstructured data.


We can go on like this for a while, but I do not want to bore you with the details. So, let’s summarize first and I will deliver a compressed list of further aspects afterward which you may take note of or skip altogether.

If you do not strategically manage data science in your enterprise you may expect another area of proliferation which you should urgently avoid!

I can help you with that. My approach is to combine data science with an architecture development cycle. Proven methods and tools will help you to master the inherent complexity and get the most out of data science for your business. You can leave the details to me.

The Details

Data science as a discipline delivers methods like the one we have discussed above. Yet, it also

  • combines subjects like
    • computer science
    • math & statistics
    • business domain knowledge
  • involves interdisciplinary roles like
    • Data Engineer
    • Data Scientist
    • Business Analyst
    • Product Owner / Project Manager
    • Developer
    • User Interface Specialist
  • implies many skills like
    • programming
    • working with data
    • descriptive statistics
    • data visualization
    • statistical modeling
    • handling Big Data
    • machine learning
    • deploying to production
  • is done with many tools like
    (only top 3-4 in each category named here)
    • programming languages
      • SQL
      • Python
      • R
    • databases
      • MySQL
      • MS SQL Server
      • PostgreSQL
      • Oracle
    • Big data platforms
      • Spark
      • Hive
      • MongoDB
      • Amazon Redshift
    • Spreadsheets, BI, Reporting
      • Excel
      • Power BI
      • QlikView

And the list is growing steadily. A little exhausting, isn’t it? At this point latest you should be convinced that data science needs strategic attention.

Executive Summary on the Ivory Tower Syndrome

#architecture #clarity #velocity #direction

This is the executive summary of last week’s post, Oh please, get down from the ivory tower and get something done!

EA Ivory Tower Syndrome

When does it happen?

The Ivory Tower Syndrome describes an often seen drift of EA initiatives dealing mostly with themselves focusing solely on strategic management while already having lost traction and therefore acceptance by the ground force.

Why does it happen?

Some EA initiatives tend to focus more on strategic reporting to upper levels and try to govern by code of law only. But, the ground force in terms of actual projects and product development, needs support for their huge amount of concise work that has to be done with granted budget and milestones. In a law-only approach they feel like not being supported but only punished (missing the carrot in “carrot and stick”).

A common misconception of EA initiatives of companies is that they can work like political government and urban planning. But, as analogy of how e.g. power grids are managed (or water grids, gas grids, metro systems, and so on), companies often only provide a fraction of needed services.

How to avoid and improve?

  • An adequate EA authority shall be balanced with a compact code of law.
  • The EA authority shall collaborate with other authorities like revision and portfolio manager.
  • Do not be jurisdictional because companies have no jurisdiction compared to politics and urban planning.
  • Align objectives of managers with your EA strategy or vice versa.
  • Implement cost saving services for each of your laws (get the tiger some teeth).
  • Include projects and product development in a community. Communicate outstanding achievements. Recognized employees drive acceptance for you!
