Using time-driven activity-based costing to support library management decisions: A case study for lending and returning processes
(2014-01-01) Sigüenza Guzmán, Lorena Catalina
With the rapid increase in the demand for new digital services, the high cost of information, and the dramatic economic slowdown, libraries have been pressured to improve their services at lower costs. To cope with these conditions, library managers must improve their knowledge and understanding of cost behavior, as well as be aware of the different costs involved in the library. Time-Driven Activity-Based Costing (TDABC) is a cost management technique that allows for developing accurate cost information on a wide range of activities. Few case studies have been implemented in libraries regarding very specific processes such as interlibrary loan and acquisition processes. More research is still needed to determine whether TDABC is useful and feasible to implement for a more extensive set of library activities. Through an analysis performed at an academic library in Belgium, this document introduces TDABC as a useful method for supporting lending and returning processes. © 2014 by The University of Chicago.

Transformational leadership and stakeholder management in library change
(Igitur Utrecht Publishing And Archiving Services, 2014-01-01) Sucozhañay Calle, Dolores Catalina; Zhimnay Valverde, Cristian Fabián; Sigüenza Guzmán, Lorena Catalina
This article aims to analyse the role of library managers as change agent when implementing Library 2.0, using transformational leadership and stakeholder management approaches. To do so, a case study in a Latin American academic library was performed. The experiences acquired for a period of six years were analysed, during which three library managers were involved in managing change. Qualitative data from documents, interviews, and observations were collected, and qualitative analysis methods were used to obtain in-depth understanding of the change process. Results show that lack of transformational leadership and stakeholder management contribute to delayed implementation and limited adoption of innovations. Although library managers recognized the importance of different stakeholders to implement changes, they did not apply systematic and proactive strategies to define and manage them. All in all, library managers should be trained as change agents, with emphasis on transformational leadership and stakeholder management skills.
Management tools for process mapping and modeling in assembly industry
(978-303094261-8, 2022) Arcentales Carrión, Rodrigo Nicanor; Colina Morles, Eliezer Null; Sucozhañay Calle, Dolores Catalina; Duran, Regina; Sigüenza Guzmán, Lorena Catalina
In a highly globalized world affected by economic policies and a latent COVID-19 pandemic, companies need to organize or reorganize to achieve efficient operations. The correct management of organizations has led their administrators to adopt resourceful management models that guide their activities towards fulfilling their objectives. Thus, management tools have been presented as an effective alternative to control processes and activities. According to a previous study, the main tools that allow process mapping and modeling are Business Process Management (BPM), Business Process Reengineering (BPR), and Event Process Chain (EPC). This article analyzes their characteristics based on compatibility and affinity with four case studies dedicated to the assembly industry using this previous study. In addition, the advantages and disadvantages of the three tools related to the possible adaptability in the four companies are studied. This work uses qualitative qualification matrices, which answer specific questions, determine the potential improvement of organizational management, and create a methodology for mapping and modeling processes.
Models, guidelines and trends for process quality management: a literature review
(Springer, 2020) Guacho Ayala, Anthony Steve; Jara Molineros, Ana Carolina; Sigcha Quezada, Erik Alejandro; Arcentales Carrión, Rodrigo Nicanor; Sigüenza Guzmán, Lorena Catalina; Jara Molineros, Ana Carolina
Although process quality management is a mainstay for achieving success in business, it does not have a unique concept that helps its definition and application. This is due to a large amount of information that can be found in the existing bibliography, resulted from the countless diversity of opinions and theories that have emerged over time. Consequently, the difficulty to find a solid and valid pronouncement that serves as a basis to build a model of process quality management was one of the reasons to perform this work, intending to define which components or guidelines to be considered for management. With this goal in mind, a systematic literature review has been performed to cover most of the theories and models currently existing around the concept of quality management. This research covers a period of ten years, between 2009 and 2018, focusing on the industrial sector. Among the main results, it has been possible to establish the identification of the most used models of quality management, the most important guidelines, and the main benefits or challenges for the integration of a process quality approach within strategic management.
Análisis de tiempos estándar en empresas de ensamble como insumo para la toma de decisiones
(2020) Apolo Aguilar, María Daniela; Guamán Guachichullca, Noé Rodrigo; Colina Morles, Eliezer Null; Luzuriaga Andrade, Mara Alejandra; Sigüenza Guzmán, Lorena Catalina
The small and medium-sized business sector has been gaining ground in the production of goods and services worldwide, creating a highly competitive environment that forces to improve their decisions to increase productivity and organizational efficiency. A handy tool to achieve these improvements is the study of methods and times, oriented to provide information about processes, time spent in operations, as well as the calculation and improvement of standard times for the optimization of processes and costs. This article describes a procedure for obtaining standard times in operational, strategic, and support processes in four assembly companies: televisions, printed circuit boards, motorcycles, and bicycles. The times obtained in the operational processes were validated through comparisons with results reported in the specialized literature, while the times associated with administrative, strategic, and support processes were analyzed internally for the case studies considered.
A hybrid algorithm for supply chain optimization of assembly companies
(IEEE, 2019) Cevallos Tapia, Carlos Patricio; Sigüenza Guzmán, Lorena Catalina; Peña Ortega, Mario Patricio; Peña Ortega, Mario Patricio
A fundamental goal of any system is to get an optimal state. These optimal states can be found in different areas, such as medicine, engineering, or architecture. In the field of industrial engineering, one of its objectives is improving or optimizing company processes in order to increase benefits while reducing costs. In this context, an essential component is the supply chain, which is a network in that different entities, such as manufacturers, suppliers, distributors, retailers, transporters, and customers or end-users, are associated. Several optimization algorithms with different approaches have been developed to optimize the supply chain. Nevertheless, they still have problems to fulfill some requirements at once. This research aims to develop a hybrid optimization algorithm that leverages the capabilities of different approaches. This algorithm, which presents a multi-objective optimization schema, meets a tradeoff between the optimization results quality and the runtime. To this end, a manufacturing and assembly company is used as a case study to prove the algorithm. The results are also compared with other state-of-the-art algorithms using the same execution environment and general settings. Findings indicate that the hybrid algorithm converges in less time and in most cases, it could reach the global optimal.
Integrating corporate social responsibility and quality management into the TDABC costing system: a case study in the assembly industry
(2022) Vedernikova Null, Olga Null; Morocho Zurita, Carlos Villie; Sigcha Quezada, Erik Alejandro; Segarra Tapia, Silvia Lorena; Sigüenza Guzmán, Lorena Catalina
Purpose – This paper aims to show the potential of time-driven activity-based costing (TDABC) to value and integrate corporate social responsibility (CSR) and quality management (QM) processes in the assembly industry. It provides valuable insights about operational processes, sub-process, and activities within assembly companies by using TDABC’s time equations with more accurate costs for the decision-making process. Design/methodology/approach – The current paper proposes a new methodology framework with four QM and CSR implementation levels and several costing scenarios through the TDABC system. The valuation was built based on the activities of essential referents in each subject, such as ISO, Ethos Institute, and electrostatic discharge control programs. To this end, a case study in the assembly industry processes was conducted with data from a TV assembler. Findings – The results highlight that TDABC can be extended to perform a cost analysis with QM and CSR processes. The environmental management and occupational safety and health administration processes were considered part of CSR to do so. Consequently, managers can simulate the cost and impact of incorporating CSR and QMin assembly processes and thus decide the implementation degree and its corresponding planning according to the needs and available resources. In this particular case, the company increases a maximum of 12% of its resources to be socially responsible and manage its products’ quality. Originality/value – Although theoretical models on CSR have been developed, the current study provides a practical framework based on TDABC scenarios that enterprises can easily implement to support and evaluate QM and CSR processes.
A holistic approach to supporting academic libraries in resource allocation processes
(University of Chicago Press, 2015-07-02) Sigüenza Guzmán, Lorena Catalina
E-content revolution, technological advances, and ever-shrinking budgets oblige libraries to efficiently allocate their limited resources between collection and services. Unfortunately, resource allocation is a complex process due to the diversity of data sources and formats required to be analyzed prior to decision making, as well as the lack of efficient methods of integration. The contribution of this article is twofold. We first propose an evaluation framework to holistically assess academic libraries. To do so, a four-pronged theoretical framework is used in which the library system and collection are analyzed from the perspective of users and internal stakeholders. Second, we present a data warehouse architecture that integrates, processes, and stores the holistically based collected data. By proposing this holistic approach, we aim to provide an integrated solution that assists library managers to make economic decisions based on a perspective of the library situation that is as realistic as possible.
Coordinating learning analytics policymaking and implementation at scale
(2020) Pesántez Cabrera, Paola Gabriela; Solano Quinde, Lizandro Damián; Sigüenza Guzmán, Lorena Catalina; Zúñiga Prieto, Miguel Ángel
Many Latin‐American institutions recognise the potential of learning analytics (LA). However, the number of actual LA implementations at scale remains limited, notwithstanding considerable effort made to formulate guidelines and frameworks to support the LA policy development. Guidance on how to coordinate the interaction between the LA policymaking and implementation is mostly missing, leaving a difficult challenge up to practitioners. In this study we propose a coordination model to support future LA initiatives at scale. We explore the problem by comparing two cases in Belgium and Ecuador. Following up we use the LA implementation timeline as a driver for planning the interaction between the policymaking and implementation. We continue by testing an application of the model with LA experts predominantly from Latin‐American institutions, asking them to map low‐level items of the SHEILA policy framework to four implementation phases. The results of this mapping support that LA policy building can be spread over time, that it can coincide with LA implementation at scale, and that both efforts can be coordinated. It is hoped that this study will provide additional guidance for future Latin‐American and other LA initiatives.
A Software Platform for Processes-Based Cost Analysis in the Assembly Industry
(Springer, 2019) Sigcha Quezada, Erik Alejandro; Colina Morles, Eliezer Null; Morocho Zurita, Carlos Villie; Sigüenza Guzmán, Lorena Catalina; Morocho Zurita, Carlos Villie
Processes and resources management are important current discussions related to decision making in the industrial field. This fact motivates companies to search for management models to improve their processes and services continuously. In order to achieve this purpose, approaches such as Business Process Management (BPM) and Time-Driven Activity-based Costing (TDABC) are used as bases for models design. This article describes the validation process of a software platform constructed using Business Process Model and Notation (BPMN) and TDABC paradigms aimed at analyzing processes costs in assembly companies. This work contemplates a description of the methodologies applied, functionalities implemented and validations steps performed. The platform also serves to generate process diagnosis in assembly companies prior to full BPM implementation.
