Jarvis Pizzeria: Aborting a Structured Process in a Dynamic Process context

In this blog we will take a look at the way a dynamic process deals with a process that ends with an exception. We will implement this in our “Register Order” process.

We modeled the process as depicted below:

Jarvis Pizzeria: Markers and Conditions

In this post we do a deep dive into the fundamentals of markers and conditions. But first one step back, what are markers and conditions and what do they have to do with each other?

For Dynamic Processes we recognize the following markers:

  • Repeatable: controls whether a stage, activity or milestone is repeatable.
  • Auto Complete: controls the completion of a stage instance.
  • Manually Activated: controls the activation of a stage or activity instance.
  • Required: controls whether a stage, activity or milestone is required.

Next we have the following conditions:

  • Activation: additional entry criteria for a stage.
  • Enablement: additional entry criteria for a activity.
  • Termination: additional exit criteria for a stage or activity.
  • Completion: addition exit criteria for a milestone.

Jarvis Pizzeria: At the PaaS Forum

The annual Partner PaaS Forum was held in Budapest Hungary this year. The full Jarvis Pizzeria team attended the PaaS Forum and as always Jürgen delivered a great program with lots of interesting content.

On Monday, since last year in Split, the Community Day we got to take the stage and present about Jarvis Pizzeria and Dynamic Processes within the Oracle Integration Cloud. A great opportunity to show some of the highlight and content of our blog series.

Jarvis Pizzeria: The Mobile app

PCS also comes with a mobile app for the end users. It’s available for iOS and Android devices (search for ‘Oracle Process Mobile’ in the PlayStore or the AppStore) . The app provides access to tasks in both connected and disconnected mode.

Compared to the browser features, there are a few differences. These are listed in the table below (this table comes directly from the oracle documentation).

But let’s just have a look at how the app works. We have installed the app on an iPad 2017 and a Samsung Galaxy S8 phone. Continue reading

My first 100 blogs listed

This blog is a very special one for me. It is the hundredth since I started the MyFMW blog in December 2010. In 7 years and a view months writing 100 blogs brings an average of 1.14 per month. Of the 100, however, there were 43 in 2017, and the last 9 (including this one) is from 2018. So the average does not say that much.

The hundredth blog is a moment for me to look back on the past 7 years as a ‘blogger’. A lot has changed in those years. For many, blogging has now been replaced by vlogging. I also made a single attempt last year, but I did not like it that very much. But who knows, there will be a renewed attempt in 2018.

Also a question that I want to answer for myself: why do I actually blog?
I do not immediately have the illusion that my blog is extremely popular, so I do not have to do it for an audience. It will probably bring some recognition within the community, but that is what it is. But what then is the reason that I continue with it … ???
That is actually very simple. I really love learning new things, finding out how something works, exploring the limits of the possibilities, and so on. By writing down my findings, I do not forget them, and by setting goals I want to achieve, I remain motivated to continue during the tough moments. Conclusion is actually that I am just very selfish by writing for myself.

This has been the case for years, but strangely enough that has been changing lately. I am not just concerned anymore that I want to record my findings so that I do not forget them. I would also like to record a beating story from beginning to end and not just write standalone pieces. This is reflected in my BAM and PCS blogs. Although I do not know if it will ever come of it, but in line of this development I do not exclude that I will write a book someday.

Looking back

Jarvis Pizzeria: Fourth step in Implementing the Order Processing, Decision Model

In blog The various Decisions of a Decision Model we gave an overview of the various type of decisions that are available for a Decision Model. In this blog we show by means of an example that Decision Models can also be used for making complex decisions. We are going to make a decision model that determines the order of preparation of the pizzas in an order.

The order of preparation is determined by the baking time, the total preparation time of each pizza and the number of available ovens (1 pizza per oven). Let’s assume that we have an order for the following 9 pizzas:

  1. Small Margherita
  2. Large Margherita
  3. Small Pepperoni
  4. Medium Pepperoni
  5. Medium Pepperoni
  6. Large Pepperoni
  7. Small Quarttro Stagioni
  8. Medium Quarttro Stagioni
  9. Large Quarttro Stagioni

Expected outcome

The pizzas with the longest baking time are prepared first. When pizzas have the same baking time, the total preparation time is also taken into account to determine the order. As a result, to determine the sort order we first need to determine the baking time and total preparation time for each pizza.

Because not all pizzas can be prepared at the same time, pizzas that are not in the oven will have a waiting time. Once we have established the order, we can also determine the waiting time per pizza. We explain this with the help of the figure below.

Jarvis Pizzeria: The various Decisions of a Decision Model

In one of our next posts we will implement the Decision Model in the Order Process. Before we do that we first explain the various type of decisions that are available for a Decision Model.

The Decision Model editor in PCS (Process Cloud Service) or the later OIC (Oracle Integration Cloud) supports the DMN (Decision Modeling Notation) standard version 1.1, and uses FEEL (Friendly Enough Expression Language) to make decision modeling easier and more intuitive.

In DMN all decision logic is represented as ‘boxed expressions’. A ‘boxed expression’ is a graphical notation for decision logic. Within OIC we recognize the following boxed expressions: Continue reading
