The document discusses the psychology of waiting in lines for services. It introduces two "laws" - (1) satisfaction equals perception minus expectation, so managing both is important, and (2) it is difficult to make up for a poor initial experience later on. The rest of the document will explore tools for managing customers' perceptions and expectations of wait times, beginning with the idea that occupied time feels shorter than unoccupied time.
Much has been written in the business literature about managing the waiting experience. Federal Express has noted that “waiting is frustrating, demoralizing, agonizing, aggravating, annoying, time consuming, and incredibly expensive.” We intuitively know this from our own experience as well as from our patients. In this #ACEP13 presentation, Dr. Jensen gives practical tips to improve your patients' ED experience.
Learn how a shift in processes, leadership and culture to an integrated solution can put your hospital on track to achieve improved clinical outcomes, metrics and patient experiences, each of which can have a potentially dramatic financial impact.

Defining service excellence_in_facility_management_iss_january 2014Muriel Walter
This whitepaper concludes two main themes emerging in driving service excellence in FM. Firstly, that excellence is underpinned by consistency, and secondly, an absolute confidence in delivering to an agreed set of standards. But research also shows that this consistency is not enough in itself to guarantee service excellence.
La Planificación Estratégica, Enrique ClarósTrendtail
En este capítulo, a modo de ensayo, os propongo un puñado de reflexiones sobre la importancia de la planificación estratégica en el éxito de los negocios de retail. La perspectiva no será financiera, ni organizativa; no os hablaré de metodologías ni de procedimientos. Me interesan más los criterios y aprendizajes básicos, sin sofisticaciones; a veces incluso laberínticos para poder remachar conceptos, otras inacabados para que vosotros mismos –o vosotras- sigáis el desarrollo. Se trata de un enfoque a ventajas competitivas, a innovación. Un tratamiento que en retail sólo puede ser marquetiniano. Y esto ya es una primera declaración de principios.
Epistemic Interaction - tuning interfaces to provide information for AI supportAlan Dix
Paper presented at SYNERGY workshop at AVI 2024, Genoa, Italy. 3rd June 2024
https://alandix.com/academic/papers/synergy2024-epistemic/
As machine learning integrates deeper into human-computer interactions, the concept of epistemic interaction emerges, aiming to refine these interactions to enhance system adaptability. This approach encourages minor, intentional adjustments in user behaviour to enrich the data available for system learning. This paper introduces epistemic interaction within the context of human-system communication, illustrating how deliberate interaction design can improve system understanding and adaptation. Through concrete examples, we demonstrate the potential of epistemic interaction to significantly advance human-computer interaction by leveraging intuitive human communication strategies to inform system design and functionality, offering a novel pathway for enriching user-system engagements.

Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM
The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management.
The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM).

Robert Boule is a technology enthusiast with PASSION for technology and making things work along with a knack for helping others understand how things work. He comes with around 20 years of solution engineering experience in application security, software continuous delivery, and SaaS platforms.
