US decides Southwests customer service failed during flight cancellations last winter
A perceptive customer service team will always have their ear on the ground in order to stay informed of customer sentiment and consumer trends and to communicate with the public with clarity. Effectively interacting with online reviews and social media can help meet both of these needs. Our amazing customer service team is here to help you with anyquestions you have while using Dialogue. (3), (4) By applying formative qualitative evaluation methods during the first two iterations and a summative quantitative evaluation method at the end of the third iteration, we operationalize the human risk and effectiveness strategy in a naturalistic framework. Gladly utilizes machine learning technology and a comprehensive platform to ensure your agents are ready to handle your customers’ needs and concerns.
- The reason is that only a few survey participants attempt to capture several variables at once to benefit from the slot filling function of the open SDS.
- Given the sensitivity of such information, many users have privacy concerns (Lopatovska et al. 2020).
- Such an overview would help to guide future DSR projects for a more rigorous design process.

- However, prior studies on CSE and technology acceptance are not conducted in a specific context of conversational agents; consequently, these findings may not be fully generalizable in the specific context of this type of technology.
Similarly, prior research has concluded that interactions with voice assistants, as is the case with SDSs, should be designed differently than in conventional human–computer interactions (Schmitt et al. 2021). Among others, the human-like design of voice assistants should be context- and task-dependent. Therefore, the investigation of the main similarities and differences between task-oriented and social SDSs in future research would help to enhance the understanding of how to design desirable AI-based digital assistants for different task types. SDSs can be differentiated in task-oriented and non-task-oriented systems (Hussain et al. 2019; Mairittha et al. 2019). Task-oriented systems are designed to assist users in performing basic tasks in short dialogs, such as booking a flight or purchasing a product, whereas non-task-oriented systems are configured to simulate a natural conversation that resembles human-to-human interactions (Hussain et al. 2019). The focus of our study is on task-oriented SDS, as we explore customer service, which is generally about solving a specific request or concern.
When the product is a different color or size than what they ordered
Younger user groups tend to prefer the features of the open SDS, whereas the older user groups clearly opt for the closed SDS. Although there is still room for improvement with respect to error recovery and completion success rate, users appreciate the elements of the open variant, such as open expression, friendliness, and humanness. Nevertheless, we believe that this study contributes to practice by proposing a design theory that helps to improve the development dialog strategies of SDSs for enhancing the user experience in the customer service context.
Thus, the findings concerning error recovery strategy indicate further issues for improvement. To date, a wealth of terms is frequently used for different kinds of dialog systems, including digital assistants, chatbots, conversational agents, and machine conversation systems (McTear et al. 2016, p. 39; Luger and Sellen 2016; Diederich et al. 2019a). Dialog systems can process concerns and inquiries from customers based on text- or speech-based inputs. Speech as an interaction modality in customer service remains very popular with customers (zendesk 2019). This is especially true for the elderly who are not as familiar with typing (Pfeuffer et al. 2019; Gupta 2021). A further limitation of this study is that it primarily focuses on optimizing efficiency and user experience when developing the design theory, neglecting socio-economic issues.
With regard to the perceived humanness as one of the hypotheses (H1), we find support for the notion that the open SDS is perceived more human-like than the closed system. First, they are consistent with social response theory (Nass and Moon 2000; Moon 2000) and support the human–human trust perspective, according to which anthropomorphic characteristics tend to positively affect user trust (Gnewuch et al. 2017; Seeger and Heinzl 2018). Accordingly, we can confirm the findings of previous studies that human-like characteristics are considered beneficial for the design of conversation-based technologies when the system is intended to substitute a human expert, for example for customer support (Diederich et al. 2020). Aside from the task-oriented acts, dialog control acts are considered important for a smooth and successful communication according to dialog theory (Bunt 2000). Dialog control acts comprise social acts and behaviors for natural communication purposes. Anecdotal evidence has shown that anthropomorphic characteristics are not necessarily related to a higher trustworthiness of a system; instead, their impacts depend on the specific context.
2 Dialog strategies for Speech Dialog Systems
Aside from the provided design knowledge, our study shows in a particular context the dialog strategy that is preferred by users to create a user-friendly and efficient human–computer dialog. Thus, our study contributes to the body of knowledge in behavioral research by enhancing the understanding of user preferences toward different dialog strategies. The survey participants generally prefer the flexibility of the open system, which allows the user to fill several slots at once and helps to determine the course of the system.
Second, although two researchers are involved in this study to achieve interrater agreement (Krippendorff 1989), the process of literature screening and assessment and the qualitative analysis of the evaluation results may be affected by selection biases (Templier and Paré 2018). Customer service scripts are written prompts used by customer service teams to confirm and resolve customer issues or questions. A customer service script can be used for phone conversations, chat boxes, email, and social media conversations. As a company, we are focused on delivering engaging and inspiring interactions and creating positive impressions that last a lifetime! The final important set of requirements is related to the functional design of the dialog flow, which defines the rules for the entire dialog course and thus describes the users’ different action alternatives (Handoyo et al. 2018).
The younger user groups of 18–24 and 25–44 years old prefer the open SDS, whereas the older user group of 45–65 years old clearly opt for the closed SDS. After the second iteration, the instantiations are prepared for the final evaluation, a two-phase experiment with 205 participants. The properties to be evaluated for the comprehensive summative evaluation are captured in the hypotheses in Table 4. The hypotheses represent “statements required to test whether the design satisfies the requirements” (Gregor and Jones 2007, p. 319). Gladly is a customer service platform for digitally-focused B2C companies who want to maximize the lifetime value of their customers. Unlike the legacy approach to customer service software, which is designed around a ticket or case to enable workflows, Gladly enables radically personal customer service centered around people to sustain customer loyalty and drive more revenue.
Thus, we initially develope a system architecture based on the five DPs, which serves as a foundation for the subsequent development of the prototypes using the evolutionary prototyping approach. Consistent with the principles of the DSR approach, the evolutionary prototyping method is characterized by a process of constant revision, refinement, and testing of an artifact (Davis 1992). This method enables us to develop, test, and redesign the SDS in several iterations until we meet the requirements. The prototypes are iteratively tested by potential users and modified based on the users’ feedback (Carter et al. 2001). Only when the SDS is considered to meet the requirements, the evolutionary prototyping of the respective DSR iterations is completed and the next activity can begin (Activity 4). Given the significance of a diligent evaluation process, it is considered essential to every DSR project (Hevner et al. 2004; Peffers et al. 2007).
Deliver personalized one-to-one customer experiences, at every touchpoint, every time.
However, the users are more satisfied with the control system in the closed SDS due to the higher predictability of communication. On average, both tasks are completed faster in the open system, which is also confirmed by the subjective perception of the users. The majority of users indeed perceive the system response accuracy of the open system as higher than that of the closed system, based on their subjective perception that the open SDS makes fewer mistakes than the closed system. However, this perception is contradictory to the recorded system data, which reveal that users made more mistakes in completing the two tasks in the open system. The lower level of habitability as described above could be one reason why the number of errors is higher in the open system. The contradiction between the perceived system response accuracy and the actual number of errors based on the logging information implies that other system characteristics such as likability or perceived humanness may be more important for users of SDSs than system response accuracy.
However, the error prompts remain short and rely on the user’s initiative to independently correct the error. With this purpose in mind, we draw on the DSR methodological approach of Peffers et al. (2007), which provides a structured development process with several continuous design and evaluation cycles. The development and evaluation of the SDS design theory takes place in three iteration rounds, as illustrated in Fig. Additionally, we describe the development of the SDS prototypes based on the elaborated requirements and DPs.
In task-oriented dialogs in customer service, the goal of users is to express their concerns and inquiries in natural language to ensure that their requests are effectively handled. To this end, we identify the requirements related to DP prompt design, menu design, persona design, confirmation strategy, error management, and functional design. These requirements are essential to support the user through the dialog and to achieve the desired objective. When investigating the habitability of the open SDS compared to the alternative (H2), we find that the closed SDS is perceived as more habitable than the open SDS. One reason for the higher habitability with the closed SDS is that this form is still predominant in business practice (Dale 2016).
We log the user activities (i.e., completion time), errors made (number of corrections), and number of dialog steps required to complete the tasks. The log file is automatically created by an integrated function of Dialogflow as soon as the participants begin their task by calling the Adventure Guru. In the second phase of the experiment, the participants complete an online survey that captures the user experience with both instantiations. The constructs and items operationalizing the survey constitute existing validated measures (cf. Appendix A.4). We use the construct of perceived humanness from Gnewuch et al. (2017) to test H1 (resp. DP2, with the aim of enabling customers to have a human-like dialog with an SDS). To test H2 and thereby examine the DP3 design, we use the construct of habitability, which refers to “the extent to which the user knows what to do and knows what the system is doing” (Hone and Graham 2000, p. 23). In addition, the construct of system response accuracy is utilized to test H3, which examines the DP4 design of error handling, and the construct of likability is used for testing H4 by assessing preferences between an open (or DP1) and a closed menu design (or DP6).
2 System Design
Therefore, a major aim is to create high-quality conversations that resemble human interaction in terms of not only expression but also the emotions generated (Lee and Choi 2017). According to the academic literature, users desire certain human characteristics when interacting with dialog systems. First, a dialog system should be honest and authentic (Przegalinska et al. 2019), that is, it should neither deny its status as a machine nor behave like one (Luo et al. 2019).
The available options explicitly express that the user should repeat and not rephrase the input. If the user still fails to select the desired option, the system assistance is increased. For example, the system advises to follow the exact wording of the menu options before repeating them afterwards (DP4). With the presented design theory, we contribute to research and practice by providing a consistent set of design principles, propositions for further improvement, and future research avenues for addressing an important class of problems in human–computer interaction research. This is of particular importance in the context of customer service, as research on the design of conversational agents that can help to increase user experience is lacking to date (Gnewuch et al. 2017).
Due to the tree navigation structure of the closed dialog strategy, an incorporated “return” command ensures easy and quick navigation corrections during the booking process. Additionally, by selecting the “main menu” command, the user can cancel ongoing processes and return to the main menu, where only the welcome prompt is repeated, as the user should still be familiar with the command options. After selecting a menu path (e.g., “book experience”), the menu items of the next navigation level are listed and necessary input variables such as experience category, experience, number of participants, and date are successively captured. If errors occur despite the coherent closed dialog strategy, the SDS responds with the prompt “sorry, I’m probably hearing particularly badly today. ” The SDS admits its mistake in a funny and friendly way and asks the user to repeat the statement. Different responses of the error prompt ensure that the SDS does not repeat itself in the course of the dialog (DP2).
A summative evaluation comprising a two-phase experiment with 205 participants yields positive results regarding the user experience of the artifact. This study contributes to design knowledge for SDSs in customer service and supports practitioners striving to implement similar systems in their organizations. The tasks provide a clear and comprehensible use case for the interaction with the SDSs and allowed for comparability across participants.
The open expression mode should therefore be possible throughout the SDS to enable a human-like conversation and to support the human–human perspective according to social response theory (Nass and Moon 2000; Moon 2000). Given the varying preferences and needs of different user groups, system design should allow for tailored levels of help prompts. Hence, help prompts should be more detailed when the user specifically asks for support. Additionally, more contextualization is required to avoid unnecessary errors and misunderstandings. Instead of allowing users to access the help at any time, this function should only be possible in the dialog steps in which help is relevant.
