procedure: 1a: a particular way of doing or of going about the accomplishment of something 1b (1): a particular course of action (2): a particular step adopted for doing or accomplishing something (3): a series of steps followed in a regular orderly definite wayYou can spot the seeds of the scalability problem right away with repeated use of the word “particular” and with the phrase “regular orderly definite way” in the definition. Given the degree of product/service customization desired today, and the accelerating rate of change, how much business activity still occurs in a particular and regular orderly definite way? The answer, of course, is less and less all the time. ‘Exceptions’ have become the rule. The essential characteristic of procedures is that they flow. The flow comprises the steps by which a thing is intended to become a different thing (or the same thing in a different state). The essence of ‘procedure’ is therefore that something will be hopefully transformed. For sure, that’s a very basic, very important, very necessary part of any business capability. The problem arises taking procedure beyond that point. Something declarative, in contrast, doesn’t flow. It just states something that must (or should) be true.
declarative: 2: having the characteristics of or making a declaration : ASSERTIVE; specifically : constituting a statement that can be either true or falseBusiness rules are that way; they simply give guidance. They don’t do anything. They don’t flow anywhere. They can’t be anything other than true or false. In short, business rules are fundamentally different than procedures. Big-P Process The traditional procedural paradigm (I’ll call it Big-P Process) embeds business rules in procedures (and in process models and in procedural code).What happens when you treat things that could be declarative in a procedural way? You get bloat. You lose business intent. You produce needless complexity. And you also get what I call configuration stagnation. As you scale, these problems grow exponentially. How many business rules are we talking about? Any given business capability easily has hundreds, sometimes thousands of business rules – especially when you begin to factor in the know-how needed to make smart operational business decisions. And don’t our businesses increasingly depend on ever more complex know-how? Is there any end to that trend in sight? At the scale of today’s business, the Big-P Process paradigm simply doesn’t work. It results in ungovernable business operations and unretainable know-how. Big-P solutions are like setting the business in concrete. It’s all so unnecessary and so counterproductive. It’s just not smart. Configuration Agility The key question for agile business capabilities is how the business is configured (and quickly reconfigured) for operation at any given point in time. In the Big-P paradigm, the building-blocks become thoroughly entangled with flow (procedure). The result is essentially a semantic dead zone. Because things that could be expressed declaratively aren’t, the opportunity is lost to use logic to automatically evaluate business rules (read ‘business practices’) for conflicts, anomalies and other logical defects. The future clearly does not lie in that direction. Instead, it lies with granular, declarative, semantically-rich specification of business configurations in building-block fashion. It lies with the paradigm that can produce the optimal configuration agility. In addition to procedures, smart configuration models will feature at least these other building blocks for business capabilities, all specified at the business level:
- business rules
- operational business decisions
- structured business vocabularies (concept models, also known as fact models)
- business goals and risks
- business events
