Can you remember a year when your business both (1) grew in a healthy way and (2) changed more slowly than the year before? Besides a company’s early startup years, such would be the exception, not the rule. So, in 2011, your business is likely to continue accelerating its pace of change. A recent Forrester report, The Top 15 Technology Trends EA Should Watch: 2011 To 2013, named both business rules and SOA policy as items for your watch list — because both of them help accelerate business change.
Back in the mainframe days — and even into minicomputer, client/server, and Web applications — nearly all of the business logic for every application was tightly wrapped up in the application code. A few forward-thinking programmers might have built separate parameter files with a small bit of business-oriented application configuration, but that was about it. But, business changes too quickly to have all of the rules locked up in the code.
Some have tried the route that businesspeople ought to do their own programming — and many vendor tools through the years have tried creatively (though unsuccessfully) to make development simple enough for that. But, business is too complex for businesspeople to do all of their own programming.
Enter business rules, SOA policy, and other ways to pull certain bits of business logic out of being buried in the code. What makes these types of approaches valuable is that they are targeted, contained, and can have appropriate life cycles built around them to allow businesspeople to change what they are qualified to change, authorized to change, and have been approved to change.
