BPM Institute Live Training: Decision Modeling With DMN San Francisco

Live Training as part of Brainstorm San Francisco

The Decision Model and Notation (DMN) is a standard for decision modeling in the process of being adopted by the Object Management Group. It provides a graphical notation for specifying decisions so that decision making can be modeled separately from business processes. DMN allows both technical users and business users to describe, model and manage decision-making by providing a notation that is intuitive to business users yet able to represent complex decision making. The DMN specification also provides a mapping between the graphics of the notation to the underlying constructs of execution environments such as business rules management systems and predictive analytic environments.

The primary goal of DMN is to provide a standard notation that is readily understandable by all business stakeholders. These business stakeholders include the business analysts wh

5 steps to decision-centric legacy modernization

Last week I emphasized four key facts about legacy modernization. To move forward you need to find the legacy code that represents business decisions such as a pricing engine (what price is this product for this customer), eligibility logic (is this customer eligible for this offer or service), approval rules (can this claim be auto-approved) and replace those parts of the application with Decision Services.This week I am going to walk through the 5 steps involved in this kind of decision-centric legacy modernization (and don’t forget we have a webinar on legacy modernization coming up with our partner TechBlue).

  1. Analyze the code to find and isolate the decisions.
    The first step is to find the pieces of legacy code that make decision

4 reminders about legacy modernization

Legacy systems remain critical to many (most) organizations and so legacy modernization is still a hot topic (which is why we have a webinar on legacy modernization coming up with our partner TechBlue). With that in mind, as at is has been a while since I blogged on this topic, I thought I would share a few thoughts. First, this week, four key reminders when modernizing legacy applications:

  1. You don’t need to modernize the whole application
    Often you can dramatically improve a legacy application by modernizing just part of it. Many pieces of legacy applications work just fine and have few, if any, change requests pending. Maintaining these pieces as legacy code is not expensive and replacing it all would be high risk so why not leave it alone while focusing on the pieces that don’t work well, especially the pieces that have high maintenance costs.
