Closed-loop communication

Last updated

Closed-loop communication is a communication technique used to avoid misunderstandings.

When the sender gives a message, the receiver repeats this back. The sender then confirms the message, commonly using the word “yes”. When the receiver incorrectly repeats the message back, the sender will say “negative” (or something similar) and then repeat the correct message. If the sender, the person giving the message, does not get a reply back, he must repeat it until the receiver starts closing the loop. To get the attention of the receiver, the sender can use the receiver's name or functional position, touch his or her shoulder, etc. [1]

Informally, at least in engineering organizations, closing the loop means establishing an informal communication channel with another individual or organization. The expression "going open loop" is used to express the idea that someone has lost discipline, acted out of control.

Steps of Closed-Loop Communication

Closed-loop communication is a form of communication that revolves around a three-step process. The steps are listed below:

  1. Sending a message
  2. Receiving the message
  3. Verifying the message

One way to conceptualize closed-loop communication is to picture a circle. If the circle is left with an open then anything can get in. In the case of verbal communication that may be misinformation, distractions, etc. However, when the circle is completely closed, there is much less of a chance for anything to get in and leaves fewer chances for a mistake. The process of participating in this form of communication is called “closing the loop." [2]

Military Origins

The origins of this form of communication come from military radio transmissions. Originally this was referred to as the two-way radio communication protocol. The goal was to effectively and safely share critical information with little margin for error. This was especially important when those transmitting and receiving the messages were separated by distance and not communicating face to face. Examples of this would be the usage of the following phrases:

  1. Roger That (message received)
  2. Wilco (I will comply)
  3. Over and Out (conversation is done)

Using these phrases ensures that not only was the message transmitted but also that it was understood. They are a good example of “closing the loop” when communicating because it leaves minimal room for miscommunication to occur. [3]

Closed-Loop Communication in Aviation

Similar to the military, the Aviation profession also uses closed-loop communication. In this field, closed-loop communication is known as Crew Resource Management. Adopting this form of communication has minimized loss of separation, safety has improved, and fewer errors have occurred. Some goals of Crew Resource Management are: [4]

  1. Decreased number of errors
  2. Greater efficiency
  3. Less stress and stress-inducing scenarios
  4. Increased Safety

As more research was done on the cause of flight accidents it was discovered that most of them occurred due to insufficient communication as opposed to technical failures, lack of knowledge, or pilot error. From this Crew Resource Management, a take on Closed-Loop Communication was created in hopes of decreasing accidents that become possibly fatal and overall detrimental. It improved the following: [5]

  1. Interpersonal communication
  2. Improved problem-solving skills
  3. Teamwork
  4. Solution centeredness
  5. Enhanced decision making
  6. Situational awareness

Three Parts of Closed-Loop Communication

Closed-loop communication can involve three parts/steps which are as follows: [6]

Call-out

Check-back

Teach-back

Specifically, the teach-back method has been used in medical situations with patients, families, medical staff, and caregivers. The results are as follows: [6]

  1. An exchange of information and responsibility
  2. Verbal communication
  3. Eliminates the room for misunderstanding
  4. Creates space for clarification
  5. Information gets acknowledged by the receiving end of the information

Closed-Loop Communication in Health Care

Closed-loop communication isn’t just beneficial when it comes to the military or aviation. This form of communication has also been shown to be useful in many other disciplines. Often closed-loop communication is seen being used in medical settings, such as a hospital or doctor's office. Doctors, nurses, and other personnel are encouraged to use closed-loop communication with their colleagues, patients, and patient’s families. When used correctly this process will leave no gaps or space for misunderstandings. However, the consequences can be extensive if the communication loop is left open, especially in medical scenarios. Examples are listed below: [7]

  1. Patients could be given incorrect doses
  2. Misunderstanding of the instructions of their medical care
  3. Left not processing what they were just told

It is critical to use closed-loop communication in health care because up to 30% of lawsuits regarding incapacitated or dead patients that are successful are due to miscommunication; according to Control Risk Insurance Company. The benefits are numerous and listed below: [8]

  1. Closed-loop communication eliminates vagueness in discussions surrounding instructions and new information
  2. Creates a space where questions are welcomed
  3. Allows clarification and verification of information to occur

Overall closing the loop in a healthcare setting has been shown to reduce the rates of error when receiving and providing care.

Other Usages of Closed-Loop Communication

Outside of the medical field the practice of closed-loop communication is still effectively used and has many benefits. Professional environments are spaces where closed-loop communication is frequently in use; requiring follow-up, feedback, and clarification. Within businesses, closed-loop communication creates an improvement in coworkers’ interpersonal communication, effectiveness and accuracy of work done, and team bonding. [3]

The Transmission Control Protocol (TCP) is one of the main protocols of the Internet protocol suite. It originated in the initial network implementation in which it complemented the Internet Protocol (IP). Therefore, the entire suite is commonly referred to as TCP/IP. TCP provides reliable, ordered, and error-checked delivery of a stream of octets (bytes) between applications running on hosts communicating via an IP network. Major internet applications such as the World Wide Web, email, remote administration, and file transfer rely on TCP, which is part of the Transport layer of the TCP/IP suite. SSL/TLS often runs on top of TCP.

Automatic repeat request (ARQ), also known as automatic repeat query, is an error-control method for data transmission that uses acknowledgements and timeouts to achieve reliable data transmission over an unreliable communication channel. ARQ is appropriate if the communication channel has varying or unknown capacity. If the sender does not receive an acknowledgment before the timeout, it re-transmits the message until it receives an acknowledgment or exceeds a predefined number of retransmissions.

Direct Client-to-Client (DCC) is an IRC-related sub-protocol enabling peers to interconnect using an IRC server for handshaking in order to exchange files or perform non-relayed chats. Once established, a typical DCC session runs independently from the IRC server. Originally designed to be used with ircII it is now supported by many IRC clients. Some peer-to-peer clients on napster-protocol servers also have DCC send/get capability, including TekNap, SunshineUN and Lopster. A variation of the DCC protocol called SDCC, also known as DCC SCHAT supports encrypted connections. An RFC specification on the use of DCC does not exist.

Two-way communication is a form of transmission in which both parties involved transmit information. Two-way communication has also been referred to as interpersonal communication. Common forms of two-way communication are:

Sender Policy Framework (SPF) is an email authentication method which ensures the sending mail server is authorized to originate mail from the email sender's domain. This authentication only applies to the email sender listed in the "envelope from" field during the initial SMTP connection. If the email is bounced, a message is sent to this address, and for downstream transmission it typically appears in the "Return-Path" header. To authenticate the email address which is actually visible to recipients on the "From:" line, other technologies such as DMARC must be used. Forgery of this address is known as email spoofing, and is often used in phishing and email spam.

The Resource Reservation Protocol (RSVP) is a transport layer protocol designed to reserve resources across a network using the integrated services model. RSVP operates over an IPv4 or IPv6 and provides receiver-initiated setup of resource reservations for multicast or unicast data flows. It does not transport application data but is similar to a control protocol, like Internet Control Message Protocol (ICMP) or Internet Group Management Protocol (IGMP). RSVP is described in RFC 2205.

Radiotelephony procedure includes various techniques used to clarify, simplify and standardize spoken communications over two-way radios, in use by the armed forces, in civil aviation, police and fire dispatching systems, citizens' band radio (CB), and amateur radio.

Client-to-client protocol (CTCP) is a special type of communication between Internet Relay Chat (IRC) clients.

In computer science, message passing is a technique for invoking behavior on a computer. The invoking program sends a message to a process and relies on that process and its supporting infrastructure to then select and run some appropriate code. Message passing differs from conventional programming where a process, subroutine, or function is directly invoked by name. Message passing is key to some models of concurrency and object-oriented programming.

In data communications, flow control is the process of managing the rate of data transmission between two nodes to prevent a fast sender from overwhelming a slow receiver. Flow control should be distinguished from congestion control, which is used for controlling the flow of data when congestion has actually occurred. Flow control mechanisms can be classified by whether or not the receiving node sends feedback to the sending node.

Selective Repeat ARQ or Selective Reject ARQ is a specific instance of the automatic repeat request (ARQ) protocol used to manage sequence numbers and retransmissions in reliable communications.

Decoding, in semiotics, is the process of interpreting a message sent by an addresser (sender) to an addressee (receiver). The complementary process – creating a message for transmission to an addressee – is called encoding.

Procedure words are words or phrases limited to radio telephone procedure used to facilitate communication by conveying information in a condensed standard verbal format. Prowords are voice versions of the much older procedural signs for Morse code which were first developed in the 1860s for Morse telegraphy, and their meaning is identical.

Communication noise refers to influences on effective communication that influence the interpretation of conversations. While often looked over, communication noise can have a profound impact both on our perception of interactions with others and our analysis of our own communication proficiency.

To disseminate, in the field of communication, is to broadcast a message to the public without direct feedback from the audience.

Aviation communication refers to the conversing of two or more aircraft. Aircraft are constructed in such a way that make it very difficult to see beyond what is directly in front of them. As safety is a primary focus in aviation, communication methods such as wireless radio are an effective way for aircraft to communicate with the necessary personnel. Aviation is an international industry and as a result involves multiple languages. The International Civil Aviation Organization (ICAO) deemed English the official language of aviation. The industry considers that some pilots may not be fluent English speakers and as a result pilots are obligated to participate in an English proficiency test.

In data networking, telecommunications, and computer buses, an acknowledgment (ACK) is a signal that is passed between communicating processes, computers, or devices to signify acknowledgment, or receipt of message, as part of a communications protocol. The negative-acknowledgement is a signal that is sent to reject a previously received message or to indicate some kind of error. Acknowledgments and negative acknowledgments inform a sender of the receiver's state so that it can adjust its own state accordingly.

<span class="mw-page-title-main">Models of communication</span> Simplified representations of communication

Models of communication are simplified representations of the process of communication. Most models try to describe both verbal and non-verbal communication and often understand it as an exchange of messages. Their function is to give a compact overview of the complex process of communication. This helps researchers formulate hypotheses, apply communication-related concepts to real-world cases, and test predictions. Despite their usefulness, many models are criticized based on the claim that they are too simple because they leave out essential aspects. The components and their interactions are usually presented in the form of a diagram. Some basic components and interactions reappear in many of the models. They include the idea that a sender encodes information in the form of a message and sends it to a receiver through a channel. The receiver needs to decode the message to understand the initial idea and provides some form of feedback. In both cases, noise may interfere and distort the message.

Linked Data Notifications (LDN) is a W3C Recommendation that describes a communications protocol based on HTTP, URI, and RDF on how servers (receivers) can receive messages pushed to them by applications (senders), as well as how other applications (consumers) may retrieve those messages. Any web resource can advertise a receiving endpoint (inbox) for notification messages. Messages are expressed in RDF, and can contain arbitrary data.

<span class="mw-page-title-main">Schramm's model of communication</span> Interaction model of communication

Schramm's model of communication is an early and influential model of communication. It was first published by Wilbur Schramm in 1954 and includes innovations over previous models, such as the inclusion of a feedback loop and the discussion of the role of fields of experience. For Schramm, communication is about sharing information or having a common attitude towards signs. His model is based on three basic components: a source, a destination, and a message. The process starts with an idea in the mind of the source. This idea is then encoded into a message using signs and sent to the destination. The destination needs to decode and interpret the signs to reconstruct the original idea. In response, they formulate their own message, encode it, and send it back as a form of feedback. Feedback is a key part of many forms of communication. It can be used to mitigate processes that may undermine successful communication, such as external noise or errors in the phases of encoding and decoding.
