    The Agile Business Rule&amp;nbsp;Development methodology&amp;nbsp;details all the different activities the project team may&#xD;
    need to follow to develop a business rule application. Starting from&amp;nbsp;from rule discovery to rule set deployment&#xD;
    and maintenance, this method helps to develop rule set using an agile, iterative approach. We can group the set of&#xD;
    activities into five groups. Those groups&amp;nbsp;are used to build an iterative&amp;nbsp;development of each rule set and&#xD;
    decision service:&#xD;

    The following diagram represents&amp;nbsp;how&amp;nbsp;the five groups of activities can be executed in a process flow&#xD;
    using&amp;nbsp;loops to implement short iterations. The rule set will grow following these cycles to get closer to the&#xD;

    A first phase includes a short time period&amp;nbsp;where the development team splits the day into two parts, executing&#xD;
    discovery workshop in the morning (2 or 3-hour sessions), then performing some analysis and documentation for the&#xD;
    remaining of the day. The team iterates on these two steps during 2 to 5 days maximum, depending on the number of rules&#xD;
    and their complexity.&#xD;

    describes the point in the process (task, activities, transition) where there is a lot of decision points involved&#xD;

&lt;/p>&#xD;
&lt;p class=&quot;MsoNormal&quot; style=&quot;MARGIN: 3pt 0in&quot;>&#xD;
    Once a certain level of discovery progress is done, the development team should be able to define the structure of the&#xD;
    rule project: the rule set parameters (input-output business objects), the basic sequencing of the rules, also called&#xD;
    &lt;i style=&quot;mso-bidi-font-style: normal&quot;>&lt;a class=&quot;elementLink&quot;&#xD;
    href=&quot;./../../../abrd/guidances/termdefinitions/ruleflow_27B05442.html&quot;&#xD;
    guid=&quot;__2sZYBCWEdyJtJ3PbfdVDw&quot;>ruleflow&lt;/a>&lt;/i>, and the first major elements of the &lt;a class=&quot;elementLink&quot;&#xD;
    href=&quot;./../../../abrd/guidances/templates/bom_6D3FB2B2.html&quot; guid=&quot;_sruW0gjqEdyj5bYZ0eCR5g&quot;>Business Object Model&lt;/a>.&#xD;
    The team then should be able to already implement some rules.&#xD;
&lt;/p>&#xD;
&lt;p class=&quot;MsoNormal&quot; style=&quot;MARGIN: 3pt 0in&quot;>&#xD;
    The idea is to execute the step “Rule Authoring” as soon as possible to uncover possible analysis and design issues.&#xD;
    Indeed, most of the rules look good on paper but real issues arise most of the time during implementation and test. The&#xD;
    next morning workshop session communicates the issues back to the business team. This leverages the feedback loop&#xD;
    approach and provides an efficient mechanism to build a pragmatic, adequate and business-relevant executable rule&#xD;
    set.&lt;span style=&quot;mso-spacerun: yes&quot;>&amp;nbsp;&lt;/span>&#xD;

    The second phase still does discovery and analysis, to complete the rule harvesting.&#xD;

&lt;/p>&#xD;
&lt;p class=&quot;MsoNormal&quot; style=&quot;MARGIN: 3pt 0in&quot;>&#xD;
    From our experience based on hundreds of successful implementations of decision-support systems, executable rules are&#xD;
    more important than the ones defined on paper or in requirement tracking tools in a non-executable form.&#xD;
&lt;/p>&#xD;

    agile statement is at the core of this cycle. Based on a Test-Driven Development (TDD) approach the goal of this phase&#xD;
    is to implement a set of test scenarios with real or close to real data, to test the rules within their corresponding&#xD;
    rule sets and their targeted execution context&lt;/span>.&#xD;
&lt;/p>&lt;br class=&quot;MsoNormal&quot; style=&quot;MARGIN: 3pt 0cm&quot; />&#xD;

&lt;p class=&quot;MsoNormal&quot; style=&quot;MARGIN: 3pt 0in&quot;>&#xD;
    The&amp;nbsp;day-to-day authoring activities can be seen as a set of little steps including&amp;nbsp;test case implementation,&#xD;
    writing rules, executing them, and doing&amp;nbsp;some validation with the team members.&#xD;
&lt;/p>&#xD;
&lt;p class=&quot;MsoNormal&quot; style=&quot;MARGIN: 3pt 0in&quot;>&#xD;
    This cycle is still using short daily&amp;nbsp;loops:&#xD;
&lt;/p>&#xD;
&lt;ul style=&quot;MARGIN-TOP: 0in&quot; type=&quot;disc&quot;>&#xD;

    &lt;li class=&quot;MsoNormal&quot; style=&quot;MARGIN: 3pt 0in; tab-stops: list .5in; mso-list: l0 level1 lfo1&quot;>&#xD;
        Loop on Analysis, Authoring and Validation to author executable rules, complete the analysis, do some unit testing&#xD;
        and address/resolve issues.&#xD;
    &lt;/li>&#xD;
    &lt;li class=&quot;MsoNormal&quot; style=&quot;MARGIN: 3pt 0in; tab-stops: list .5in; mso-list: l0 level1 lfo1&quot;>&#xD;
        Loop on a bi-daily basis on Discovery, Analysis, Authoring and Validation. The discovery will be used to complete&#xD;
        the scope of the rule set and address the issues identified during implementation.&#xD;
    &lt;/li>&#xD;
&lt;/ul>&#xD;
&lt;p class=&quot;MsoNormal&quot; style=&quot;MARGIN: 3pt 0in&quot;>&#xD;
    The cycle 3 should finish after 2 to 3 weeks. The goal is to release the rule set within an integrated development&#xD;
    build in order to start testing the business application with the decision service. The rule set should only be 40 to&#xD;
    60% complete. Business users or rule writers will then elaborate and complete it in cycle 5 (Enhancement). But at the&#xD;
    end of cycle 3, the Object Model used with the rule should be at least 90% complete, and the project structure should&#xD;
    be finalized.&#xD;
&lt;/p>&#xD;

    is sent to the rule engine to fire rules and infer decisions. During the previous phases the development team develops&#xD;
    a set of test scenarios with realistic or real data which will trigger rule execution. Those test scenarios will be&#xD;
    executed during the integration phase to support end to end testing. In the future they will serve as non-regression&#xD;
    test suite.&lt;/span>&#xD;

    includes authoring, validation and deployment. It is still possible to do some short face-to-face discovery activities&#xD;
    with the Subject Matter Expert to address and wrap-up some issues and questions. But with this approach, the team&#xD;
    responsible for maturing the rule set to close to 100% coverage can be another team than the initial development one.&#xD;
    This team is more business-oriented. As owners of the rule set and the business policies, they can develop at their own&#xD;
    pace as they have all of the core infrastructure implemented by the development team.&lt;/span>&#xD;
&lt;/p>&#xD;

    is important to note that there will be some needs to enhance the object model or physical data model to add some new&#xD;
    facts, attributes, or entities.&amp;nbsp;Those modifications will follow the standard release management process of the&#xD;
    core business application.&lt;/span>&#xD;

    phase approach has&amp;nbsp;many advantages in driving the development process of a Rule Set. It involves all the key&#xD;
    stakeholders and prepares for the future maintenance. As a business application using a rule engine is, per design,&#xD;
    very agile and supportive of changes, the analysts team needs to understand early in the development process how the&#xD;
    components exposed to the rule engine work together, how to change, add, remove rules, how to deploy them...&lt;/span>&#xD;
