What are some of the challenges and limitations of applying SPC to service processes?

One of the main challenges of applying SPC to service processes is the high degree of variability and heterogeneity of services. Unlike products, services are intangible, perishable, inseparable, and co-produced by the provider and the customer. This means that the quality and outcome of a service can vary depending on the expectations, preferences, and behaviors of the customer, as well as the skills, attitudes, and actions of the provider. Therefore, it can be hard to define and measure the specifications and standards of a service, and to identify and eliminate the sources of variation and error.

Challenges in applying SPC to service processes include intangible nature of services, variability due to human factors and difficulty in defining and measuring quality metrics ??. Limited control over inputs and outputs and the complexity of interactions may hinder effective implementation ???♂?. Lack of standardized processes and resistance to change pose additional barriers ??. However, adapting SPC tools to service contexts and fostering a culture of continuous improvement can mitigate these challenges ??.
Another challenge of applying SPC to service processes is the difficulty and cost of collecting and analyzing data. Service processes often involve multiple steps, interactions, and outcomes, which can be hard to track and quantify. Moreover, service data may be subjective, qualitative, or emotional, which can be hard to translate into numerical or categorical values. Furthermore, service data may be sparse, incomplete, or unreliable, which can affect the validity and reliability of the statistical analysis. Therefore, service providers need to carefully select and design the data collection methods and tools, and to ensure the accuracy and consistency of the data.

I 100% agree, your SPC can only be as good as your data ( I know some will say it averages out but the costs associated with the “averaging out” to yield and reliability is in my opinion too high)
A third challenge of applying SPC to service processes is the influence and impact of customer involvement. As mentioned earlier, services are co-produced by the provider and the customer, which means that the customer plays an active role in the process and the outcome. Therefore, the customer can be a source of variation, error, or feedback, depending on their expectations, satisfaction, or complaints. Therefore, service providers need to consider and manage the customer's input and output, and to involve them in the quality improvement efforts.
A fourth challenge of applying SPC to service processes is the implementation and evaluation of process improvement actions. SPC involves using control charts, Pareto charts, cause-and-effect diagrams, and other tools to monitor, analyze, and improve the process performance. However, service processes may be complex, dynamic, or customized, which can make it hard to apply the same tools or techniques across different situations or segments. Moreover, service processes may be affected by external factors, such as market demand, competition, or regulation, which can limit the scope or effectiveness of the improvement actions. Therefore, service providers need to adapt and modify the SPC tools and techniques to suit their specific context and goals.
A fifth challenge of applying SPC to service processes is the alignment and support of the organizational culture. SPC requires a culture of quality, learning, and innovation, where the employees are empowered, engaged, and motivated to participate in the quality improvement initiatives. However, service organizations may face barriers or resistance to change, such as lack of leadership commitment, resources, or training, or fear of losing autonomy, creativity, or customer loyalty. Therefore, service providers need to foster and sustain a culture of quality, where the employees are aware, involved, and rewarded for their contributions to the SPC process.
Despite the challenges and limitations of applying SPC to service processes, there are some alternative or complementary approaches that can help service providers to enhance their quality and performance. For instance, service quality models such as SERVQUAL or SERVPERF measure the gap between customer expectations and perceptions of the service quality. Additionally, service blueprinting maps the service process from the customer's perspective, identifying critical points of contact, evidence, and failure. Furthermore, service recovery involves detecting, correcting, and preventing service failures in order to restore customer satisfaction and loyalty. Lastly, service innovation focuses on creating or improving services, processes, or delivery methods based on customer needs, feedback, or trends.

I expected this article to suggest that SPC can, in fact, be applied to service processes despite the challenges and limitations but the viewpoint seems to be that it's best to skip SPC and go with alternatives. I've seen SPC (and statistical thinking) add real value in service processes, so I think there is cause for much more optimism than expressed herein.
