Agent Assist
Employee supportAI support during a customer service employee’s work, for example with answers, summaries or work instructions. The employee conducts the customer conversation and assesses what to use.
Practical example
In practice: A colleague asks a question about return conditions and receives relevant information with a source to consult.

Average Handle TimeThe average time needed to handle a contact. Depending on the measurement setup, conversation time, time on hold and after-call work may be included. Specify which components your report uses.
Practical example
In practice: Do not compare chat and telephony without accounting for simultaneous chats and differences in contact reason.
AI agent
AI that can determine next stepsAn application that uses an AI model to choose next steps and use tools to achieve a goal. The permitted actions and boundaries are configured in advance.
Practical example
In practice: An agent can retrieve available delivery slots before suggesting a permitted change.
Compare a chatbot and an AI agentAI governance
Agreements on responsible AI useThe allocation of responsibilities, decision-making and controls around AI. This includes, among other things, who may modify an application, how performance is assessed and who follows up on incidents.
Practical example
In practice: A process owner approves a new application and, together with the team, determines when human review is needed.
API
Application Programming InterfaceAn agreed way for software to communicate with other software. An API can make data available or enable an action, within the permissions granted to the connection.
Practical example
In practice: An integration retrieves the current order status. That does not automatically mean it may also modify the order.
AQM
Automated Quality MonitoringAutomatic assessment of customer interactions against established quality criteria. AI can help assess conversations on a larger scale; people remain necessary to check the criteria and outcomes.
Practical example
In practice: A reviewer examines why a conversation received a low completeness score and corrects an incorrect assessment.
View quality monitoringDegree of automation
Share of tasks handled automaticallyThe share of an agreed set of tasks or contacts that is handled automatically. The outcome depends on what you count as a task, completion and human involvement.
Practical example
In practice: Report “return requests within the pilot” separately from “all customer contacts”; these percentages are not interchangeable.
Chatbot
Conversation via a digital applicationAn application that allows someone to have a conversation, usually via text. The answers may come from fixed routes, AI or a combination of both. A chatbot can also start connected workflows.
Practical example
In practice: A web chat answers a question about opening hours or asks which order the person means.
Containment
Contacts without human handoverThe share of bot contacts that, within the chosen measurement definition, remain without being handed over to an employee. This is not automatically the same as a resolved problem: someone may also drop out.
Practical example
In practice: When containment is high, check whether customers call again later and whether their original question was actually resolved.
Context
Information surrounding a questionThe information an application takes into account when generating an answer, such as previous messages, retrieved knowledge and relevant customer data. A language model can process only a limited amount at a time.
Practical example
In practice: “And tomorrow?” only has meaning when the previous question about a delivery date is available.
Conversational AI
AI for conversationsA collective term for AI techniques that enable systems to have a conversation via text or speech. The term itself says nothing about system access, autonomy or the quality of the answers.
Practical example
In practice: An application recognizes different ways of phrasing a question and asks a clarifying follow-up question.
CRM
Customer Relationship ManagementManaging customer relationships and, in software form, recording customer data and interactions. A CRM can provide context for customer service, provided the right information and access rights are available.
Practical example
In practice: An employee can see previous contacts and therefore needs to ask fewer questions again.
CSAT
Customer Satisfaction ScoreA measure of customer satisfaction with an experience, product or service. It is often the ratio of satisfied respondents to all respondents. The wording, scale and timing of the measurement determine how you interpret the score.
Practical example
In practice: After resolving a service request, ask how satisfied the customer is and also look at how many customers respond.
Escalation
Escalating to other supportPassing an issue on because additional expertise, authority or priority is needed. An escalation can originate from a bot, but can also take place between employees or teams.
Practical example
In practice: A disputed refund is passed to a colleague who is authorized to assess exceptions.
FCR
First Contact ResolutionThe proportion of questions resolved during the first contact. Define how you determine that something has been resolved and within what period a follow-up contact still counts as relating to the same question.
Practical example
In practice: A customer does not need to contact you again about the same incorrect invoice.
Feedback loop
From signal to controlled improvementA recurring process in which you collect and assess feedback, turn it into an adjustment and check the result again. Receiving feedback does not mean that an AI model automatically retrains itself.
Practical example
In practice: An employee reports an unclear answer; the knowledge manager improves the article and tests the question again.
Generative AI
AI that creates new contentAI that generates new content, such as text, based on learned patterns and provided input. A fluently worded answer does not necessarily have to be factually correct.
Practical example
In practice: An application creates a suggested answer based on a customer question and relevant knowledge.
Grounding
Connecting answers to relevant informationSupporting or constraining model output with information relevant to the task. This can be done, for example, through retrieved documentation or verified system data. The result still needs to be assessed.
Practical example
In practice: An answer uses the current return policy instead of relying solely on general knowledge from the language model.
Hallucination
Convincing-sounding, incorrect AI outputAI output that is incorrect, fabricated or insufficiently supported, even though it may sound convincing. Better sources and checks can reduce this risk, but do not guarantee error-free answers.
Practical example
In practice: A chatbot mentions a return period that does not appear anywhere in the applicable policy.
Human handover
Handover to an employeeTransferring a conversation or task from an automated application to a human. A useful handover includes the relevant context and a clear reason for taking over.
Practical example
In practice: An employee receives the customer question, previous answers and a notification that the system action failed.
Intent
The purpose behind an utteranceWhat someone is trying to achieve with a message or statement. The same intention can be expressed using different words; a message can also contain multiple intentions.
Practical example
In practice: “Where is my package?” and “Is my order on its way?” may both be asking about delivery status.
Knowledge base
A collection of useful knowledgeAn organized collection of information, such as articles, terms and conditions, and work instructions. Its usefulness depends on being up to date, accessible, and clear to the target audience.
Practical example
In practice: An article describes which supporting documents are required for a damaged product.
Check your knowledge baseKnowledge management
Maintaining and making knowledge availableOrganizing the entire knowledge lifecycle: creating, reviewing, publishing, updating, and removing information. This includes owners, versions, and agreements about who may use which information.
Practical example
In practice: A modified procedure is assigned an owner and reviewed before employees and AI use the new version.
LLM
Large Language ModelA large language model that has learned patterns in language and can process and generate text. It is one component of an application, not automatically a complete customer service solution.
Practical example
In practice: In addition to the language model, a useful service bot also needs knowledge, instructions, integrations, and controls.
Multilingualism
Support for multiple languagesThe ability to process questions and answers in multiple languages. Language support does not yet indicate whether local terms and conditions, product names, and nuances are represented correctly in every language.
Practical example
In practice: Test the same customer question in Dutch and English and check whether the terms and conditions retain the same meaning.
NLU
Natural Language UnderstandingTechniques for deriving meaning, context, and intent from human language. NLU can, for example, help identify a reason for contacting an organization; it is different from merely recognizing words literally.
Practical example
In practice: “I can’t get in” can be recognized in a conversation about an account as a login problem.
NPS
Net Promoter ScoreA score based on the willingness to recommend an organization. The percentage of respondents giving a 9 or 10 minus the percentage giving a 0 through 6 makes up the NPS.
Practical example
In practice: 60% promoters and 20% detractors results in an NPS of 40. That is different from 40% satisfied customers.
Omnichannel
Consistency between contact channelsAn approach in which channels and relevant customer context are connected. Being reachable only by phone, chat, and email is not in itself proof that those channels also work cohesively.
Practical example
In practice: During a phone call, an employee can consult the relevant previous chat.
Prompt
Input and instructions for an AI modelThe task and information used to direct a model. A prompt can describe style, purpose, and limitations, but it does not replace access rights or technical controls for a system action.
Practical example
In practice: An instruction requests a short answer and asks the model to ask follow-up questions when necessary information is missing.
RAG
Retrieval-Augmented GenerationAn approach in which relevant information is retrieved first and then provided to a language model to formulate the answer. The quality of the information found affects the usefulness of the result.
Practical example
In practice: An application searches for the correct policy article before formulating an answer to a question about returns.
Sentiment analysis
Analysis of emotional toneAn automated assessment of the emotional tone in text or speech, such as positive or negative. Context and irony can make interpretation difficult; treat the result as a signal.
Practical example
In practice: “Well, that was handled brilliantly” can be genuine appreciation, but also sarcasm after a failed delivery.
SLA
Service Level AgreementAn agreement on the level of service to be provided, with definitions and responsibilities. Think availability, response time or resolution. A goal is only measurable if the measurement method is clear.
Practical example
In practice: Specify during which opening hours a response time applies and whether it concerns a first response or a solution.
Token
A processing unit for a language modelA piece of text or other model input that a model processes. A token can be part of a word, a word or a punctuation mark. The number of tokens therefore does not equal the number of words.
Practical example
In practice: A long conversation and attached documents together take up space within the context window.
Tool calling
Calling an external functionA model can select an available function and suggest arguments. The application validates and executes that request. Only the actual execution determines whether information is retrieved or a change is made.
Practical example
In practice: The model requests an order status through an approved function; the software checks the parameters and permissions.
Voicebot
A voice-based conversation applicationAn application that enables someone to communicate by voice. Speech recognition, conversation processing and speech synthesis are often combined. Call transfers and handling unclear speech must be deliberately configured.
Practical example
In practice: A caller asks about an appointment and can be transferred when the application does not understand the question properly.
Read about voicebotsWorkflow
A preconfigured processAn agreed sequence of steps, conditions and actions. A workflow can combine fixed rules, AI components and human approval. Not every automated workflow is therefore an autonomous AI agent.
Practical example
In practice: A returns process checks the conditions, requests approval if necessary and then creates a return label.
Explore automationNo terms found. Try a shorter search term or choose “All topics”.
Ask three questions during a demo.
A shared meaning prevents you from comparing different things with each other.
What exactly happens?
Use a real customer question to show which information is retrieved, who determines the next step and which action is performed. A product name alone does not indicate this.
When does a human take over?
Discuss missing knowledge, unusual requests and failed actions. Ask how the employee can proceed and which context remains available.
What are we actually measuring?
Ask which contacts count, what “resolved” means and how repeat contacts are identified. Always consider a shorter handling time alongside quality and customer experience.
How to compare results fairly
At the start of a pilot, record the same definitions for the team and the supplier. A difference in score can be caused by a different measurement method. Therefore, first establish a baseline measurement using the same scope as the later evaluation. The examples on this page are illustrative and do not describe a guaranteed outcome.
