FIELD

[0002] The disclosure relates generally to workflow control. The disclosure relates specifically workflow control systems.

BACKGROUND

[0003] Workflow control, including Standard Operating Procedures (SOPs), have historically been either paper or electronic view only files. The worker completes the workflow with no control system interaction.

[0004] It would be advantageous for there to be a workflow management mechanism capable of preventing the next action being performed until it has been confirmed that the previous action was completed.

SUMMARY

[0005] An embodiment of the disclosure is a workflow management system comprising an interface between an application and a control system to allow interlocks from either the application or the control system to prevent progression beyond a step of a workflow if a condition for completion has not been met. In an embodiment, the workflow management system further comprises logging activities performed in the application or by the control system; and making the activities available for reporting and analysis. In an embodiment, when a safety meeting requirement is present in a workflow, the safety meeting is initiated, managed, and recorded in the system. In an embodiment, the initiating, managing, and recording is performed by the application user; and the control system uses the safety meeting requirement as an interlock to prevent progression to the next step of the workflow. In an embodiment, the workflow management system further comprises an override system to allow users with appropriate permissions to override conditions that prevent progression through the steps of the workflow. In an embodiment, the override can be requested and granted by users from at least one of the group consisting of a server application, the control system, and a mobile application. In an embodiment, the control system comprises at least one sensor. In an embodiment, the at least one sensor confirms the state of a piece of equipment. In an embodiment, the at least one sensor confirms that the equipment is in the state the user of the app indicates prior to moving on to the next step. In an embodiment, the control system is accessed by a smart device. In an embodiment, the smart device is a phone or a tablet. In an embodiment, the application is installed on a laptop computer.

[0006] An embodiment of the disclosure is a computer application capable of interfacing with the workflow system to perform steps of the SOP while is the user is remote from the control system, and to see the status of SOP steps on demand. In an embodiment, the computer application is a server application. In an embodiment, the computer application is a mobile application. In an embodiment, the computer application is installed on a smart device. In an embodiment, the smart device is a phone or tablet. In an embodiment, the application is installed on a laptop computer. In an embodiment, the computer application further comprises a site-wide alert system based on the state of workflows. In an embodiment, the site-wide alert system prevents a user from proceeding to the next step of the workflow.

[0007] An embodiment of the disclosure is a control system comprising an interface between and a control system to allow interlocks from either the application or the control system to prevent movement to the next step of a standard operating procedure if the previous step was not confirmed complete by either the app or the control system.

[0009] The foregoing has outlined rather broadly the features of the present disclosure in order that the detailed description that follows may be better understood. Additional features and advantages of the disclosure will be described hereinafter, which form the subject of the claims.

BRIEF DESCRIPTION OF THE DRAWINGS

[0010] In order that the manner in which the above-recited and other enhancements and objects of the disclosure are obtained, a more particular description of the disclosure briefly described above will be rendered by reference to specific embodiments thereof which are illustrated in the appended drawings. Understanding that these drawings depict only typical embodiments of the disclosure and are therefore not to be considered limiting of its scope, the disclosure will be described with additional specificity and detail through the use of the accompanying drawings in which:

[0011] Fig. 1 depicts a communication flow chart initiated in the software application; [0012] Fig. 2 depicts a communication flow chart initiated by the controller; and [0013] Fig. 3 depicts a communications diagram DETAILED DESCRIPTION

[0014] The particulars shown herein are by way of example and for purposes of illustrative discussion of the preferred embodiments of the present disclosure only and are presented in the cause of providing what is believed to be the most useful and readily understood description of the principles and conceptual aspects of various embodiments of the disclosure. In this regard, no attempt is made to show structural details of the disclosure in more detail than is necessary for the fundamental understanding of the disclosure, the description taken with the drawings making apparent to those skilled in the art how the several forms of the disclosure may be embodied in practice.

[0015] The following definitions and explanations are meant and intended to be controlling in any future construction unless clearly and unambiguously modified in the following examples or when application of the meaning renders any construction meaningless or essentially meaningless. In cases where the construction of the term would render it meaningless or essentially meaningless, the definition should be taken from Webster's Dictionary 3 ^rd Edition.

[0016] 1. The integration of a smart device or computer application and a control system so that both provide workflow adherence to ensure the safety of workers and to protect equipment. In an embodiment, the workflow is a Standard Operating Procedure (SOP). In an embodiment, the smart device is a phone, tablet, or any similar electronic device. This integration is accessible and manageable from any location. This requires the development of an interface between an application (app) and a control system to allow interlocks from either the app or the control system to prevent movement to the next step of a workflow if the previous step was not confirmed complete by either the app or the control system. In an embodiment, the control system comprises a controller. The control system uses sensors to physically confirm that the equipment is in the state the user of the app indicates prior to moving on to the next step. This process integrates both real world sensors and portable access to the system status to ensure that the workflow has been followed prior to completing a task to promote safety and to protect equipment.

[0017] 2. Technology interface to improve the safety of workers and protect equipment. The development of an app that can operate on a smart device or a desktop/laptop operating system and an interface to communicate with a control system. The app and control system interface would allow for interaction between mobile or desktop technology and control systems to ensure that workflow steps are followed and critical steps confirmed by the control system to ensure the safety of workers and protection of equipment. The interface between the app and control system is crucial to elevating the effectiveness of the workflow.

[0018] 3. Mobile software applications and control systems currently operate in isolation. Creating an interface to share interlocks between an app and a control system would elevate the safety of workers and protection of equipment. The app would replace the paper or electronic workflow steps (including but not limited to a SOP) and interface with the control system to ensure that steps of the SOP are completed and confirmed before moving on to the next step. Only when the worker and the control system confirm that the conditions of the workflow have been met will the control system allow the worker to operate the piece of equipment and progress through the workflow steps. Tracking of the completion of the steps would be stored within the app database for tracking and further training. This system would allow for a true double check to ensure all equipment is in a safe state before operating.

[0019] In an embodiment, the application can be used on a smart device including but not limited to a phone, tablet, or iPad. In an embodiment, the application can be used on a laptop or desktop computer.
