 == Definition of Workflow Engine<ref>What is Workflow Engine [https://en.wikipedia.org/wiki/Workflow_engine Wikipedia]</ref> ==
-A '''workflow engine''' is a software application that manages business processes. It is a key component in workflow technology and typically makes use of a database server. A workflow engine manages and monitors the state of activities in a workflow, such as the processing and approval of a loan application form, and determines which new activity to transition to according to defined processes (workflows).[1] The actions may be anything from saving an application form in a document management system to sending a reminder e-mail to users or escalating overdue items to management. A workflow engine facilitates the flow of information, tasks, and events. Workflow engines may also be referred to as Workflow Orchestration Engines. Workflow engines mainly have three functions:

 *Determine the authority of users: Check if the current user is permitted to execute the task.
 *Executing condition script: After passing the previous two steps, the workflow engine executes the task, and if the execution successfully completes, it returns the success, if not, it reports the error to trigger and roll back the change.

 == Use Cases of Workflow Engine<ref>Typical Use Cases of Workflow Engine [https://www.processmaker.com/blog/what-is-a-workflow-engine/ ProcessMaker]</ref> ==
 Workflow engines are capable of streamlining many business processes. The following are two examples of common use cases for a workflow engine.
-*Employee Onboarding: According to research by Glassdoor, a smooth employee onboarding process can improve new hire retention by 82% and productivity by more than 70%. Many organizations continue to rely on manual employee onboarding processes, resulting in a fragmented and frustrating employee experience. With a workflow engine, an organization can ensure that each onboarding task is carried out smoothly. For example, the first task in the onboarding process may be to prepare paperwork for a new hire. Once the responsible HR employee indicates that paperwork is completed, the workflow engine can automatically notify the IT department to grant computer access. This way, no steps are missed, and the employee has everything that he or she needs to get started.

 *Approval Processes: Manual approval processes result in significant direct, indirect, and hidden costs. For example, according to data from the Center for Advanced Procurement Strategy (CAPS), the average cost per purchase order ranges between $50 and $1,000 depending on the industry and vertical. With a workflow engine, organizations can automate approval processes saving both time and money. For instance, when an employee submits a purchase request, the request is automatically routed to a supervisor for approval. Once signed, the approval is routed back to the employee. The employee can easily track the status of the request rather than spending time tracking down the supervisor for a signature.

 Workflows are typically initiated or resolved based on pre-set times and deadlines, so that when one task is completed, another is initiated for human-lead tasks. In the case of internal network server tasks, workflow engines can automate these with set, timed cycles.   Workflows route a series of tasks, pushing them from one step to the next. They not only automate tasks, but they also decrease decision-making processes by guiding the process to the most efficient step. They are designed to do so with set deadlines or with timed response. A workflow engine is designed as a group of microservices so that multiple processes can occur at once. There are two common types:

 The best workflow engine solution will depend on your needs and existing software stack. For instance, let’s say you need to have specific documents reviewed by specific individuals before approval. You would want a workflow solution that ensured each document draft made its way to everyone required to provide a sign-off. After getting the signatures, the workflow should send the completed document back to relevant stakeholders. Many organizations rely on workflow engines to help them manage financial processes. For example, a finance team could set up an expense approval workflow process to review submitted expense claims. Functions within the engine could include:
 *Make sure employees fill out form fields correctly and send them back for corrections automatically

From server and application workflow tasks to employee approval processes, data processing and onboarding, workflow technology helps you customize each of these use cases. Moreover, workflow engines typically use representational state transfer (or RESTful API) software. This technology lets applications interact in a network environment, which in turn enables your organization to integrate a workflow solution with your cloud service and other platforms you currently use.

		+	Workflow engines are capable of streamlining many business processes. The following are two examples of common use cases for a workflow engine.
		+	*Employee Onboarding: According to research by Glassdoor, a smooth employee onboarding process can improve new hire retention by 82% and productivity by more than 70%. Many organizations continue to rely on manual employee onboarding processes, resulting in a fragmented and frustrating employee experience. With a workflow engine, an organization can ensure that each onboarding task is carried out smoothly. For example, the first task in the onboarding process may be to prepare paperwork for a new hire. Once the responsible HR employee indicates that paperwork is completed, the workflow engine can automatically notify the IT department to grant computer access. This way, no steps are missed, and the employee has everything that he or she needs to get started.
		+	*Approval Processes: Manual approval processes result in significant direct, indirect, and hidden costs. For example, according to data from the Center for Advanced Procurement Strategy (CAPS), the average cost per purchase order ranges between $50 and $1,000 depending on the industry and vertical. With a workflow engine, organizations can automate approval processes saving both time and money. For instance, when an employee submits a purchase request, the request is automatically routed to a supervisor for approval. Once signed, the approval is routed back to the employee. The employee can easily track the status of the request rather than spending time tracking down the supervisor for a signature.
