Workflow Optimization

In the intricate world of business operations, efficiency isn’t just a buzzword; it’s the lifeblood of success. At its core, a company’s workflow represents the series of processes that enable it to function, from the moment a request is initiated to its final resolution. Optimizing these workflows is paramount to reducing bottlenecks, minimizing errors, and ultimately, delivering superior value to customers. In the realm of IT Service Management (ITSM) and enterprise systems, particularly within platforms like BMC Remedy (now part of BMC Helix), understanding and fine-tuning these automated processes is a continuous journey.

This article delves into the fundamental components of workflow automation, focusing on how to leverage them effectively for optimization. We’ll break down the core workflow objects, their functions, and how their strategic implementation can lead to significant improvements in operational efficiency.

Understanding the Building Blocks of Workflow

At its heart, workflow automation involves using intelligent objects to trigger actions in response to predefined conditions. In the context of systems like BMC Remedy, these objects are the backbone of dynamic process execution. The primary workflow objects we’ll explore are Active Links, Filters, and Escalations.

Active Links: Empowering Client-Side Interactions

Active Links are the workhorses of client-side automation. They are designed to execute a set of actions based on user interactions or the current state of information displayed on the user’s screen. Think of them as the “if this happens, then do that” commands that occur directly within the application interface.

Key Characteristics of Active Links:

• Triggered by User Actions: They respond to events like clicking a button, changing a field’s value, or navigating within the application.
• Client-Side Execution: Primarily operate within the user’s application window, providing immediate feedback and responsiveness.
• Versatile Actions: Can perform a wide range of actions, including displaying messages to the user, dynamically changing the appearance of fields (e.g., color), fetching data from other forms, or even initiating client-side scripts.
• Limitations: Notably, Active Links cannot be triggered directly by API programs, meaning they are tied to user interaction or specific client-side events.
• Naming Convention: If you attempt to create an Active Link with a name that already exists, the system will automatically append _c to the new name to ensure uniqueness.
• Saving Forms: When you save a form, its associated Active Links are generally not copied. However, if you rename a form, its existing Active Links are typically retained.
• Mandatory Action: An Active Link must have at least one action defined to be functional.

Practical Example: Imagine a “Request Entry” form. When a user selects “Hardware Support” from a dropdown menu, an Active Link could dynamically display a “Hardware Type” field, hide a “Software Version” field, and pre-populate a “Description” field with a default text like “Please specify the hardware issue.” This provides a tailored user experience and guides the user efficiently.

Filters: Orchestrating Server-Side Logic

Filters are the silent guardians of your data integrity and process flow. They operate at the server level, scrutinizing form transactions as they are processed. Filters are crucial for enforcing business rules, validating data, and automating complex backend operations.

Key Characteristics of Filters:

• Server-Side Execution: They run on the AR System server, meaning they have access to the database and can perform more intensive operations.
• Transaction-Driven: Triggered by specific operations on forms, such as submitting a new record, modifying an existing one, or deleting a record.
• Qualification-Based: Filters only execute if the current transaction or record meets a defined qualification (a set of criteria).
• Administrator Permissions: Filters typically run with administrator privileges, allowing them to interact with the database directly.
• Execution Order: Filters have an execution order (defaulting to 500) which dictates the sequence in which they are processed on a form.
• Interaction with Database: They are designed to interact with the database, retrieving or modifying data as needed.

Practical Example: When a new “Incident” ticket is submitted, a Filter might check if all mandatory fields (like “Urgency” and “Impact”) are populated. If not, it could prevent the submission and display an error message. Another Filter could automatically assign the ticket to a specific support group based on the “Category” selected, ensuring proper routing.

Escalations: Time-Based Process Management

Escalations introduce a temporal dimension to your workflow automation. Similar to Filters, they operate at the server level and interact with the database. However, their trigger is time-based rather than event-based.

Key Characteristics of Escalations:

• Server-Side Execution: Like Filters, Escalations run on the AR System server.
• Time-Driven Triggers: They are executed at predefined time intervals (e.g., every hour, daily) or after a specific duration has passed since a record was created or modified.
• Broad Applicability: While Filters typically act on the *current* request that meets a qualification, Escalations can find and act on *all* requests in the database that meet their defined qualification at the time of execution.
• Dedicated User: Escalations are often executed by a specific system user, commonly referred to as the ar_escalator.

Practical Example: An Escalation could be configured to automatically change the “Status” of an “Incident” ticket to “Escalated” if it remains “In Progress” for more than 48 hours. Another Escalation might send a reminder email to the assigned support agent if a “Task” is not completed within its scheduled due date.

Leveraging Workflow Objects for Optimization

The true power of workflow optimization lies in the strategic combination and intelligent configuration of these objects. Understanding their distinct roles allows for a more robust and efficient automated system.

Choosing the Right Tool for the Job

The decision of whether to use an Active Link, Filter, or Escalation depends entirely on the nature of the action you want to automate:

• For immediate user feedback, form manipulation, or guiding user input: Use Active Links.
• For enforcing business rules, data validation, and server-side record processing upon user actions: Use Filters.
• For time-sensitive tasks, automated follow-ups, or batch processing based on time: Use Escalations.

Understanding Workflow Actions

Both Active Links, Filters, and Escalations utilize a set of common actions, but some actions are exclusive to certain workflow types. This variety allows for a high degree of customization.

Common Workflow Actions and Their Applicability:

Exclusive Actions:

• Only in Active Links: DDE, Change Field, Close Window, Commit Changes, OLE Automation, Open Window, Run Macro, Wait.
• In Filters & Escalations (but not Active Links): Call guide, Go to guide label, Go to.
• In Filters but not Escalations: Notify, Log file. (Note: Notify and Log File are indeed available in Escalations as well, the table might have a slight discrepancy or focus on specific primary uses. It’s best to consult official documentation for the most up-to-date action availability.)

Deep Dive into Key Actions for Optimization:

Direct SQL: Bridging External Systems

The Direct SQL action is a powerful, albeit sensitive, tool. It allows you to execute raw SQL commands against non-AR System databases. This is invaluable for integrations, allowing your AR System workflows to interact with legacy systems or external data sources.

• Use Cases: Pushing data to external reporting databases, retrieving configuration data from other systems, or updating external system records.
• Caution: BMC strongly advises *against* using Direct SQL to modify AR System’s own internal tables (for object definitions or form data). Doing so can lead to severe data corruption and is unsupported. Stick to pushing data to external, non-AR System databases.

For official documentation on Direct SQL action, refer to BMC’s documentation portal:

• BMC Remedy Action Request System Workflow Objects (This is a general reference; specific actions may be detailed within).

Goto and Go to Guide Label: Controlling Flow

These actions provide granular control over the execution path of your workflows. They allow you to deviate from the standard sequential processing order.

• Goto: Used in Active Links and Filters. It allows you to jump to a specific point in your workflow based on an execution order number. This can be useful for repeating a set of actions or creating conditional branching without the complexity of a full guide.
• Go to Guide Label: Used in Active Links and Filters. This action is more structured, allowing you to redirect workflow execution to a labeled section within a guide. Guides are essentially organized collections of workflows, and labels mark specific entry points. This promotes modularity and reusability of workflow segments.

These actions are fundamental for creating dynamic and responsive workflows that can adapt to varying conditions.

Run Process: Executing External Commands

The Run Process action is a versatile tool that enables your AR System workflows to execute independent processes on either the client or the AR System server.

• Use Cases: Sending faxes, generating reports in specific formats, interacting with other applications, or triggering custom scripts.
• Dynamic Execution: A key advantage for optimization is that the command to be executed can be dynamically generated based on field values. This makes it highly adaptable.

Service: Interacting with Services

The Service action is used across Active Links, Filters, and Escalations. It’s designed to trigger filters that have an “Execute On” condition set to “Service.”

• Inter-system Communication: It can work with AR System Web Services to consume external services or with a Set Fields filter to consume internal AR System services.
• Data Exchange: It facilitates the passing of input field data and the retrieval of output data, enabling seamless data exchange between different systems or components.

Push Fields: Automating Data Updates

The Push Fields action is a cornerstone of data automation. It allows you to transfer values from fields in one request to another, whether it’s within the same form or across different forms.

• Efficiency: Significantly reduces manual data entry and ensures data consistency across your system.
• Flexibility: Can update or create new requests and push values from virtually any field type.
• Scope: Each Push Fields action targets one other form, but it can update multiple requests within that form.

Commit Changes vs. Run Process “PERFORM-ACTION-APPLY”

Understanding subtle differences between actions is crucial for effective debugging and optimization.

• Commit Changes: When used with a dialog box, it captures data entered in the dialog and pushes it to the parent form but doesn’t immediately save to the database. When used with a regular form, it commits the changes to the database.
• Run Process “PERFORM-ACTION-APPLY”: This is often preferred for dynamically generated workflows. While Commit Changes might appear in logs, the specific action within Run Process might not be as explicitly detailed. If your workflow logic needs to be highly dynamic and determined at runtime, Run Process offers greater flexibility.

Access Control: Governing Permissions

While not a workflow object itself, Access Control plays a critical role in workflow design. It dictates who can see, interact with, and modify data. Effectively configured Permission Groups and Roles ensure that your workflows operate within defined security boundaries, preventing unauthorized access or modifications.

Key Concepts in Access Control:

• Permission Groups: Collections of users assigned specific rights to access forms, fields, and data.
• Roles: Define responsibilities and associated permissions, often providing a more granular level of access control than groups alone.

When designing workflows, always consider how access control settings will impact their execution. A workflow might fail if the user or system account executing it doesn’t have the necessary permissions.

Troubleshooting Common Workflow Issues

Even the most meticulously designed workflows can encounter problems. Here are some common pitfalls and how to address them:

1. Workflow Not Triggering as Expected:

• Check Qualifications: Ensure the qualification criteria for your Filter or Escalation are accurate and being met by the relevant data.
• Execution Order: For Filters, verify the execution order is set correctly to avoid conflicts with other Filters on the same form.
• Active Link Triggers: For Active Links, confirm the correct client operation is being used as the trigger.
• User Permissions: Ensure the user or role executing the workflow has the necessary permissions to perform the intended actions on the target form.
• Cache Issues: Sometimes, AR System might be using cached definitions. Use the arsignal utility to force a reload. For example, arsignal -r serverName reloads definitions from the database. BMC Documentation on arsignal.

2. Performance Degradation:

• Complex Qualifications: Overly complex or inefficient qualifications in Filters and Escalations can slow down server processing. Optimize these by simplifying logic or using indexes where appropriate.
• Excessive Push Fields: While useful, too many Push Fields actions in a single workflow can impact performance. Consolidate or optimize where possible.
• Direct SQL Abuse: Frequent or poorly written Direct SQL queries can be a major performance bottleneck and a security risk. Use them judiciously and ensure they are optimized.
• Workflow Loops: Ensure your workflows don’t create infinite loops, where one workflow triggers another, which then triggers the first again, leading to system unresponsiveness.
• Production Cache Mode: For production environments with high user activity, ensure you are using “Production cache mode.” This mode allows administrative operations to create a temporary copy of the cache, so end-users are not impacted. Development cache mode can lock users out.

3. Data Corruption or Unexpected Data Changes:

• Direct SQL Risks: As mentioned, avoid using Direct SQL on AR System’s internal tables.
• Testing Thoroughly: Always test complex workflows in a non-production environment before deploying them.
• Audit Logs: Leverage AR System’s audit functionality to track changes. Audit form fields related to actions like GET ENTRY, SET, CREATE, DELETE, and MERGE can provide valuable insights into what triggered a change.

Interview Relevance

Understanding workflow optimization is a common topic in interviews for ITSM, AR System Developer, Administrator, and Consultant roles. Be prepared to discuss:

• The differences between Active Links, Filters, and Escalations and when to use each.
• The purpose and risks associated with actions like Direct SQL.
• How to troubleshoot common workflow issues.
• The importance of testing and documentation in workflow development.
• Strategies for optimizing workflow performance.
• Your experience with specific actions like Push Fields, Run Process, and Service.

Being able to articulate practical examples and demonstrate a deep understanding of these concepts will significantly boost your candidacy.

Conclusion

Workflow optimization is not a one-time task but an ongoing process of refinement. By mastering the intricacies of Active Links, Filters, and Escalations, and by employing a thoughtful approach to workflow design and troubleshooting, organizations can unlock significant gains in efficiency, accuracy, and overall operational performance.
