Appian BPM Engine

Let’s explore the Appian BPM engine in this section.

• Server Environment

The Appian BPM platform operates under a traditional 3-tier architecture, with a web server, a Java application server, and a database server at each tier. Each tier in the server architecture may operate in a shared physical environment or on separate physical servers.

Appian is designed to scale linearly, allowing organizations to grow a BPM initiative from a small department to an enterprise-wide deployment on a single platform.

• Client Elements

All client access to Appian components is via a web browser. It provides a separate Java-based SDK for developers to create new service objects and develop integrations with third-party systems.

• Web Services

Appian combines the concepts of Service-Oriented Architecture with business-user control, application logic design, and business process flow. 

Appian introduces a new way of wrapping common SOA objects, such as Web Services and Enterprise Java Beans (EJBs), into more easily understood Appian Smart Services.

The Appian Smart Service is designed to encapsulate the complex logic, WSDL mappings, compensations, and even GUI form interface into a simple, reusable service object.

Packaging complex SOA API calls into Appian Smart Services provides the perfect balance between IT control over complex integrations and API interactions.

In addition, Appian provides the infrastructure for an organization to begin building a library of service objects. It enables quick orchestration and management across processes and applications.

Furthermore, Appian comes pre-populated with over 85 process actions and over 250 rule expression actions to control all aspects of workflows and quickly create and extend the Appian Smart Services library.

 

• User Interface

Appian offers a complete, flexible environment for interacting with, monitoring, and managing enterprise process applications. Its flexible portal dashboards allow users to combine data elements to deliver comprehensive views into a process.

This might include task lists, process and task performance, and even collaboration and document sharing areas. Additionally, Appian’s support for standard WSRP portlet consumption allows users to incorporate data from across any system into a dashboard view.

Let’s learn more about the user interface in the following.

• • Appian’s portal environment can personalize and target content based on rules and display content from a variety of sources. It enables business users to modify layouts quickly with simple point-and-click techniques. 
  • Appian can identify a specific user attribute or role and highlight select content channel areas for viewing inside a dashboard.
  • It can restrict access to content at various levels. Dashboards, individual content channels, and even report rows can be secured to ensure that only users with the right access can view specific information.
  • Appian’s interface complies with Unicode and supports all language types. Appian analyzes the user’s language settings and displays portal content in the user’s preferred language.
  • Appian platform includes Appian’s Discussion Forums, Portal dashboards, and Group Server capabilities. They combine to create dynamic, targeted workspaces for team collaboration.
  • The Appian Discussion Forums allow users to have threaded conversations on any topic. Each topic can be associated with content areas, and individual posts can be rated for relevance.
  • Each forum or topic can be targeted to a specific set of users or groups, or made available to the entire community. As discussions occur, Appian will index all discussion content, enabling rapid searching to help users find answers to common questions.
    
    
• Scalability

Appian regularly conducts scalability testing on a variety of components to ensure proper performance before customer deployment.

Since Appian has a component-based architecture, portions of it may be modified or optimized to meet specific performance requirements (e.g., throughput, concurrency, or response time).

Appian components can be logically categorized into four major areas:

• • Process
  • Analytics
  • Content
  • Collaboration

Each of these major component areas is backed by one or more dedicated engine servers, each with its own usage and scalability patterns. The exact performance and scalability for each customer will depend on the specific usage scenarios in these major functional areas.

• Process
  

The Appian Process engine is designed to achieve the right balance between administrative and IT controls. It offers the flexibility to modify execution to handle daily process exceptions in a highly scalable manner.

Appian’s process execution environment is designed to be controlled and influenced by business users who know how processes should execute.

IT administrators can adjust everything from default field sizes for text inputs to looping limits for repeating activities in processes. This level of control over process behavior by administrators is key to enabling business user empowerment while ensuring reliable performance.

Appian also regularly tests and scales the process engine to ensure high performance in customer implementations. Appian test results show that the process engine can maintain reliable transaction throughput as the number of active process instances increases.

Additionally, Appian can deploy multiple process engines to load-balance process work across physical servers, enabling scaling to large volumes.

• Analytics

The Appian analytics interface provides the Appian suite with a robust, flexible reporting environment. Ad hoc reports can be easily created and manipulated by users using the out-of-the-box reporting environment native to Appian.

To prevent server performance issues in overly complex user-generated reports, administrators can set thresholds for report rendering time to limit the time it takes to render report views.

Performance results, included with each report execution, highlight column-by-column rendering times and recommendations to improve report performance. 

Appian regularly tests report rendering times in a variety of scenarios to ensure peak performance for customers. Test scenarios include loading hundreds of thousands of processes while hundreds of concurrent users view a common report.

Reports include a variety of data points and aggregations that reflect typical user report views. 

• Content

Appian’s content component provides a document storage facility for storing and searching documents both within and outside the process. Appian’s document storage facility currently stores over 11 million documents of varying sizes for a single customer, and usage continues to grow daily.

Appian maintains usage statistics for the content component at the document level, enabling deeper customer insights. The document management facility enables users to control default expirations for content in their storage centers, enabling more automated removal of outdated content.

Additionally, the content component enables full-text searching within Appian’s BPMS, restricting results to only those a user can access. Appian’s BPMS operates in an environment scaled for high usage and content performance at one of the largest Appian BPMS production installations.

• Collaboration

Appian’s collaboration component comprises portal pages and groups providing targeted work areas for users to interact and collaborate within the BPM Suite. Some of the largest Appian BPMS installations have more than 575,000 pages and 50,000 groups running in a single production environment, with heavy use of rules-based groups.

The collaboration component can be scaled as needed based on customer use. These installations, with heavy use of collaboration features, have scaled the collaboration component to maintain performance as the installations grow.

Processing Modeling

The Appian Process Modeler enables ideas to become functional, process-based applications in record time while providing insights into process metrics to improve performance quickly. 

The modeler enables business users to quickly document key business processes, explore services across an organization, and rapidly build process-based composite applications.

Delivered as a 100% web-based thin interface, the Appian Process Modeler is based on the Business Process Modeling Notation (BPMN) and uses simple drag-and-drop for fast, easy process modeling.

The Appian Process Modeler allows all fields to be made dynamic and determined at runtime. Fields such as deadlines, assignments, form inputs, and other properties can leverage the Appian Expression Editor to use predefined Appian Rules or runtime variables to build fully dynamic process models.

• Subprocesses

Appian supports the standard concept of subprocesses. Subprocesses are deployed using BPMN notation for subprocess activities. Appian Subprocesses are invoked by the parent process at runtime, enabling reuse across process models.

In the Appian Process Modeler, users can drill into, preview, and open subprocesses directly from the parent process.

• Shared Data Space

Appian employs a highly scalable data architecture specifically tuned for real-time process and application environments, using the native COTS (commercial off-the-shelf) database, Kdb by Kx Systems.

Kdb is a non-proprietary, commercial database platform optimized for real-time, in-memory performance and designed to meet the specific needs of a robust BPMS. The Kdb database platform is designed to capture, analyze, compare, and store data at high speed and in high volume.

Kdb operates as an in-memory environment, but is more than just an in-memory database platform. Kdb provides a fully relational database management system with time-series analysis, handling data in memory and on disk.

For advanced applications such as process event handling, decision rules, and reporting, it is essential to compare streaming process data with historical data.

Traditional approaches that combine a streaming or in-memory database with a reporting or OLAP database cannot deliver the performance necessary for real-time business. 

Time delays are unavoidable in these traditional architectures when real-time execution data must be transferred to a separate analytics environment tuned for reporting and analysis.

This time gap prevents real-time rules and decisions from being made as new process actions are executed. Appian’s use of the Kdb database platform prevents this time gap and enables real-time business decisions for all process actions.

Data stored in the Kdb platform can be easily exported to a third-party relational database system, such as MySQL, Oracle, or MS SQL Server, for independent analysis and reporting. 

Appian provides process actions for capturing all related process data and migrating to RDBMS systems. Database administrators concerned about data access can readily access all information in Appian using this feature.

Furthermore, the Kdb platform is extremely simple to maintain. There are no requirements to index data columns to optimize reporting or rework the table schema. Simple scripts are provided for managing the data.

• Forms

The Appian Forms Designer allows users to design rich web forms that can be interacted with during in-process actions. It provides a unique, web-based, extensible design environment that enables business users to create rich user forms with minimal IT involvement.

IT users can further extend the Appian Forms environment by adding new service objects, enabling business users to create forms that integrate with existing IT systems easily.

The Appian Forms Designer is geared toward users familiar with Microsoft Office, including the common design elements needed to create a rich form experience. Design elements in the Appian Forms environment include:

• • Tab Layouts
  • Expandable and Collapsible Sections
  • Common Form Inputs – Text, Numbers, Dates, etc.
  • Field Validation
  • Dynamic Form Actions
  • Rich Text Editing
    
    
• Time

Appian supports escalations and alerts on any task or process in the system. Escalations can be added to a task by navigating to the task properties and selecting the “Add Escalation” action.

Each escalation includes a configurable timer action that can be set for the task deadline or any time before or after it. The escalation, once triggered, can send alert notifications, event actions, change priority levels, or even automatically reassign the activity to an alternate user.

Appian also offers task scheduling and a calendar to set default working hours. The task scheduling feature enables process designers to schedule a task to occur on a specific date or on a relative date based on the process data.

The process modeler would configure this on the “Scheduling/Setup” tab of a step in the process modeler for a timer event. This enables activities in a process to be scheduled in advance.

Appian also includes a Process Engine to orchestrate and reroute system and human activities. Appian also supports advanced orchestration concepts, including timer events, rules, and exceptions. Exception events are necessary to ensure proper orchestration of actions and to compensate for errors.

Exception events could be triggered by a rule, a timer, or a message (external or internal). For example, if the subprocess below is not completed within a specified time, the timer exception on the subprocess will activate and execute the web service to roll back the work in the subprocess.

• Process Optimization and Simulation

Appian includes a process simulation interface embedded inside the Appian Process Modeler. The simulation interface captures expected lag and work durations for each task, as well as the expected distribution patterns for each gateway within a process model.

Once configured, the Appian simulation environment will report aggregated lag and work duration metrics for each node in the model. Bottlenecks can be easily identified from simulation results.

Business Rules

The Appian Rules environment enables users to create a central repository of reusable business rules for use across the organization. Each rule is access-controlled, allowing select users to modify individual rules. As rules change, new versions are created, and older versions are stored for historical reference.

Rules inside Appian go far beyond simple decision logic in a process step. Appian rules may be applied to any form element, process attribute, report, or even group membership. A rule can just as easily control how content is rendered in a report or a form as dynamically determine the proper path for a process.

Integration

Appian includes native connectors for common interfaces, such as relational databases (RDBMS) and Java Messaging Service (JMS). It also includes a set of integration tools that extend Appian’s API to connect Application-layer logic and data to external systems, including AS/400, PeopleSoft, SAP, Microsoft, and Oracle.

Appian’s Integrated Development Environment (IDE) and associated tools facilitate custom integration and development, while Appian’s web services interface helps developers loosely couple Appian with external applications. 

Once developed, these interfaces can be used directly in the Appian Process Modeler as Appian Smart Services to orchestrate business-user integration within a process.

Organizational Structure

Appian provides a complete organizational modeling tool that allows administrators and users to create ad hoc teams, hierarchical organizational structures, and user roles for use across the platform.

All organizational models can be imported from common directory structures, such as Microsoft Active Directory and LDAP. Appian also provides dynamic organizational modeling capabilities with the Appian Groups Server.

The Appian Groups Server is an integrated feature of the Appian BPM suite that enables administrators and managers to manage security and groups seamlessly in the growing BPM environment.

As new users enter the system or change positions, attributes, groups, roles, and security settings, all must be updated to ensure proper task assignment and security access. Appian simplifies the administration of groups and roles with a dynamic rule-based system.

Administrators can set up a variety of group types in Appian, including extended group attributes, public and private groups, rule-based group membership, and dynamic rule-based group hierarchies.

Rule-based membership and hierarchies allow groups to self-administer as user and group attributes change. The Appian Groups Server saves administrators and managers countless hours by helping them keep up with daily personnel changes across an organization.

Process Adaptability

Appian allows processes to be modified “in-flight” and to adapt to process changes during runtime. Process owners can open and edit in-flight processes as they run, change process data, dynamically activate and cancel tasks, and trigger escalations and events.

Running processes can now be modified to include these new actions and steps, and these actions can affect any future processes.

No downloads are required, nor is any complex scripting or coding required to modify processes. Upon saving the changes, the user can choose whether to apply them to individual processes or to the process model, forcing other processes to adopt the change as well.

Process Lifecycle Management

Appian provides a complete platform for designing, executing, managing, and optimizing business processes to achieve results rapidly. 

The Appian BPMS platform provides the capabilities to build and deploy new process models rapidly, monitor their efficiency, optimize actions, and adopt changes.

These features include:

• Native version control of Process Models and Rules
• Migration of Processes between Systems
• Real-time Analytics of Process Performance
• Bottleneck Analysis and Optimization of Process Efficiency
• In-flight modification to adopt changes

Monitoring, Measurement, and Management Information

Appian’s integrated analytics functionality gives organizations complete visibility into key business operations, making it easier to anticipate trends, issues, and opportunities, and to react accordingly.

With Appian’s real-time analytics, reporting dashboards, and business activity monitoring capabilities, organizations can:

• Enhance control over key processes with personalized dashboard reporting, notifications, and alerts.
• Accelerate response to change by dynamically re-routing processes based on real-time performance information.
• Quickly identify process bottlenecks and optimize business process performance.
• Develop a culture of continuous process improvement.

Appian provides real-time, dynamic analytics on all process-related data in the system, configurable through a web-based interface. Appian captures both key business metrics and process performance data for aggregation into detailed report views.

Report designers may aggregate and filter business data to provide new insights into process performance. For example, beyond simple task performance, report designers can aggregate task performance metrics based on values captured in processes, such as key suppliers or costs.

This flexible reporting environment enables designers to quickly see how process performance is impacted by the content and business data flowing through each process.

Report dashboards in Appian enable managers to view real-time performance across all operations quickly. Each report is personalized to the specific users, providing a unique view based on their access to process information and the layout of each report. 

Reports may be displayed in a variety of formats, including tabular, pie, and bar charts. Each report can be quickly toggled between views to gain new insight into report data. Key Performance Indicators may also be displayed on graphical reports or displayed as graphical indicators in tabular reports.

Appian captures detailed Business Activity Monitoring (BAM) performance data across all activities completed in the Appian process environment. Appian BAM performance data can be displayed in the graphical reports discussed previously or directly in the Appian Process Modeler.

This unique view allows process owners to view real-time and historical performance information while monitoring or editing a process. Bottlenecks and process inefficiencies can be quickly identified and corrective action taken immediately inside the web-based process modeling environment.

Appian provides interfaces for managers and administrators to easily browse user and group directories and navigate to specific users or group task lists to manage work items directly. From the interface, tasks can be reassigned, raised in priority, canceled, paused, or even restarted so a user can complete a task again.

Appian’s reporting environment allows managers to create task views across users and groups to monitor and manage work completion from an aggregate view, while drilling into task details for individual routing decisions.

Security in Appian is managed at the process level rather than the task view level, providing better granular control over task security. 

For example, a manager might have the right to manage tasks for the Expense Reporting process but not for Human Resources processes. When a task view includes tasks from both processes, only the Expense Reporting tasks are shown to the manager.

Additionally, process security in Appian can be made dynamic based on the process stages. At certain points, a manager might have greater control, but as the process changes, security rights to manage or even view it can change for every user.
