Abstract
The way in which business process models are typically deployed emphasizes their use in a high‐level design or the capture of an existing process. At these stages evaluation of the model takes place only in informal and rudimentary ways. The real evaluation effort begins only with the output of the design process, e.g. an implementation of information technology (IT) support system. Explores the benefits and feasibility of evaluating a process model at an early stage of its creation. Anticipates two advantages. First, errors or invalid design concepts are detected earlier with consequent savings in cost. Second, non‐IT‐relevant aspects can come to light at an appropriate stage. Looks first, at the value of modelling goals. Second, presents in outline a design method for modelling business processes in which the concept of the goal is fundamental. Third, looks beyond the current scope of this method to the issue of evaluating the process designs. Concludes that business process models can be evaluated at the design stage, but the knowledge gained is only partial. Summarizes the strengths and weaknesses of the approach and describes some open questions.

This paper aims to present a tool-supported approach for visualising personas as social goal models, which can subsequently be used to identify security tensions.
Abstract
Purpose
This paper aims to present a tool-supported approach for visualising personas as social goal models, which can subsequently be used to identify security tensions.
Design/methodology/approach
The authors devised an approach to partially automate the construction of social goal models from personas. The authors provide two examples of how this approach can identify previously hidden implicit vulnerabilities and validate ethical hazards faced by penetration testers and their safeguards.
Findings
Visualising personas as goal models makes it easier for stakeholders to see implications of their goals being satisfied or denied and designers to incorporate the creation and analysis of such models into the broader requirements engineering (RE) tool-chain.
Originality/value
The approach can be used with minimal changes to existing user experience and goal modelling approaches and security RE tools.

Abstract
Purpose
This study aims to examine how students with different goals differ in their subjective well-being, including academic self-efficacy (ASE) and affect at school (AAS). There are four goal orientations that motivate students to achieve academic performance. Therefore, this study examined the relationship between the four dimensions of achievement goals (AGs), ASE and AAS. It also examined five relationship models between these variables.
Design/methodology/approach
This study was conducted using a survey method with a questionnaire on 516 students at several private universities in Yogyakarta who have been studying for at least two years. After testing the validity and reliability of the measurements, correlation testing was conducted to determine the relationship between the two variables. Furthermore, testing of the five relationship models was conducted using structural equation modeling (SEM) with a two-step approach.
Findings
The findings showed that each goal was directly related to students' well-being with a diverse relationship nature. Furthermore, mastery-approach goals (MApGs) were the types that most consistently have a positive effect on students' well-being. Also, performance-avoidance goals (PAvGs) consistently and negatively affected students' well-being, while performance-approach goals (PApGs) produced various influences and relationships. In addition, mastery-avoidance goals (MAvGs) are among the four AGs that still need to be studied, especially in educational settings. This is because they had no effect on ASE either directly or indirectly.
Research limitations/implications
The limitation of this study was using cross-sectional data and self-report in data collection. Furthermore, the respondents were limited to private university students, and they were few in number.
Practical implications
MApGs had a positive effect on ASE and AAS, while PAvGs can reduce ASE and cause negative effects. Therefore, higher institutions in Indonesia need to provide a curriculum that can increase students' curiosity, creativity and involvement in the learning process. This will make them confident in their abilities and have a positive attitude in school and the society. Also, this study showed that a PApG is not a negative goal because it can increase students' confidence in their abilities. This competency feeling needs to be fostered because it encourages them to increase knowledge and learning content, as well as increase their positive effects.
Originality/value
This paper addressed the need to understand how to generate and increase students’ motivation.

Abstract
Purpose
This paper aims to introduce the goal-oriented requirements extraction approach (GOREA). It is an elicitation approach that uses, specifically, healthcare business goals to derive the requirements of e-health system to be developed.
Design/methodology/approach
GOREA consists of two major phases: (1) modelling e-health business requirements phase and (2) modelling e-health information technology (IT) and systems requirements phase. The modelling e-health business requirements phase is divided into two main stages: (1) model e-health business strategy stage and (2) model e-health business environment stage. The modelling e-health IT and systems requirements phase illustrates the process of obtaining requirements of e-health system from the organizational goals that are determined in the previous phase. It consists of four main steps that deal with business goals of e-health system: (1) modelling e-health business process (BP) step; (2) modelling e-health business goals step; (3) analysing e-health business goals step; and (4) eliciting e-health system requirements step. A case study based on the basic operations and services in hospital emergency unit for checking patient against COVID-19 virus and taking its diagnostic testing has been set and used to examine the validity of the proposed approach by achieving the conformance of the developed system to the business goals.
Findings
The results indicate that (1) the proposed GOREA has a positive influence on the system implementation according to e-health business expectations; and (2) it can successfully fulfil the need of e-health business in order to save the citizens life by checking them against COVID-19 virus.
Research limitations/implications
The proposed approach has some limitations. For example, it is only validated using one e-health business goal and thus it has to be authenticated with different e-health business goals in order to address different e-health problems.
Originality/value
Many e-health projects and innovations are not established based on robust system requirements engineering phase. In order to ensure the success delivery of e-health services, all characteristics of e-health systems and applications must be understood in terms of technological perspectives as well as the all system requirements.

Abstract
Presents a linear goal programming (LGP) model, which can be used to derive an optimal daily production schedule for JIT production systems. Also provides an explanation of how a detailed post‐optimal LGP analysis can enable a decision maker to examine the effects of production scheduling in a JIT “mixed‐model” production environment. To illustrate the informational efficacy of the proposed JIT‐based LGP model, presents an illustrative example.

Abstract
Purpose
Most of the process models concentrate on who does what, when, i.e. on the description of the operational performance of tasks. The goal driven approaches try to establish a close relationship between the “whys” and the “whats”. The former captures the strategic goals of the organisation whereas the latter tells us how they are achieved through tasks carried out by actors. In addition, managers do not naturally make the distinction between what to achieve (the goal) and the manner to achieve it (the strategy). This confusion often leads to the expression of manners as goals. In order to make clear the fundamental distinction between these two concerns and to master the complexity of process modelling, this paper seeks to propose a goal‐perspective, the map‐driven process modelling approach.
Design/methodology/approach
The map representation system conforms to goal models in the fact that it recognises the concept of a goal but departs from those by introducing the concept of strategy to attain a goal.
Findings
A business and its supporting system change in a concurrent way. In order to help the propagation of the intentional changes onto operational ones, we adopted the two levels hierarchical spiral process model. The intentional spiral deals with the production of the business process models using the map formalism and the operational one deals with the specifications of the supporting systems.
Originality/value
A business process is defined in terms of goals and strategies of reaching these goals. The approach allows choosing an appropriate level of details when analysing and redesigning business processes.

Abstract
Purpose
The purpose of this paper is to extend PriS (privacy safeguard), a privacy requirements engineering method for eliciting and modelling privacy requirements during system design, with the addition of privacy-aware cloud-based concepts to assist analysts to reason and model about privacy in cloud environments.
Design/methodology/approach
An analysis of previous findings on the file of cloud privacy based on previous work has been conducted and a set of privacy-related concepts that need to be considered during privacy analysis for cloud-based systems have been revealed. These concepts were used for extending the conceptual model of PriS.
Findings
The main finding of the paper is the design of a new, novel conceptual model that assists analysts and designers in reasoning about privacy in cloud environments. A new template using the JSON (Javascript notation object) format has been introduced for better expressing the privacy requirements along with the related concepts presented through the conceptual model, thus letting the developers to better understand the findings during the design stage and better guide them to the implementation of the respective solution.
Research limitations/implications
The design of a cloud-based process that will guide analysts in detail for eliciting and modelling the identified privacy-related requirements is the limitation and in parallel the next step of the specific work presented here.
Practical implications
The conceptual model has been applied on a real case scenario regarding its efficiency on capturing and mapping all necessary concepts for assisting analysts proceed with the design of the privacy-aware system. The results were positive, all concepts were easy to use and totally understandable from the design team and the stakeholders and the use of the JSON template received very positive comments, especially from the developer’s team.
Originality/value
The paper presents a novel conceptual model for reasoning about privacy requirements in the cloud. The applicability of the proposed model has also been tested on a real case study.

Abstract
Purpose
This paper seeks to develop a model for the assignment of employees to workplaces. Assignment methods are of high relevance in practice because employees should be assigned to workplaces according to their competences and preferences to ensure that motivated employees carry out tasks effectively and efficiently.
Design/methodology/approach
Two goal programming models are introduced with inputs and valuations using the analytic hierarchy process.
Findings
The two goal programming models for the assignment of employees to workplaces, which take into account both employee competences and preferences as well as workplace competence requirements and attributes, seem to be effective in helping to arrive at an optimal assignment decision.
Research limitations/implications
In practice, one major problem is that the input data for the goal programming models are not updated regularly. Thus, the documentation of the competence profiles and the preferences of the employees might be out of date or incomplete.
Originality/value
The development of the two goal programming models which could be applied immediately in practical competence management is what makes the work valuable and addresses a gap in the modelling of personnel assignment methodologies.

Abstract
Purpose
The purpose of this paper is to introduce a new agent-based simulation model of bilateral negotiation based on a synthesis of established theories and empirical studies of negotiation research. The central units of the model are negotiators who pursue goals, have attributes (trust, assertiveness, cooperativeness, creativity, time, etc.) and perform actions (proposing and accepting offers, exchanging information, creating value, etc).
Design/methodology/approach
Methodologically, the model follows the agent-based approach to modeling. This approach is chosen because negotiations can be described as complex, non-linear systems involving autonomous agents (i.e. the negotiators), who interact with each other, pursue goals and perform actions aimed at achieving their goals.
Findings
This paper illustrates how the model can simulate experiments involving variables such as negotiation strategy, creativity, reservation value or time in negotiation. An example simulation is presented which investigates the main and interaction effects of negotiators’ reservation value and their time available for a negotiation. A software implementation of the model is freely accessible at https://tinyurl.com/y7oj6jo8.
Research limitations/implications
The model, as developed at this point, provides the basis for future research projects. One project could address the representation of emotions and their impact on the process and outcome of negotiations. Another project could extend the model by allowing negotiators to convey false information (i.e. to bluff). Yet another project could be aimed at refining the routines used for making and accepting offers with a view to allow parties to reach partial settlements during a negotiation.
Practical implications
Due to its broad scope and wide applicability, the model can be used by practitioners and researchers alike. As a decision-support system, the model allows users to simulate negotiation situations and estimate the likelihood of negotiation outcomes. As a research platform, it can generate simulation data in a cost- and time-effective way, allowing researchers to simulate complex, large-N studies at no cost or time.
Originality/value
The model presented in this paper synthesizes in a novel way a comprehensive range of concepts and theories of current negotiation research. It complements other computational models, in that it can simulate a more diverse range of negotiation strategies (distributive, integrative and compromise) and is applicable to a greater variety of negotiation scenarios.

Abstract
New developments in concepts and approaches to job stress should incorporate all relevant types of resources that promote well-being and health. The success resource model of job stress conceptualizes subjective success as causal agents for employee well-being and health (Grebner, Elfering, & Semmer, 2008a). So far, very little is known about what kinds of work experiences are perceived as success. The success resource model defines four dimensions of subjective occupational success: goal attainment, pro-social success, positive feedback, and career success. The model assumes that subjective success is a resource because it is valued in its own right, triggers positive affect and emotions (e.g., pleasure, cf., Weiss & Cropanzano, 1996), helps to protect and gain other resources like self-efficacy (Hobfoll, 1998, 2001), has direct positive effects on well-being (e.g., job satisfaction, cf., Locke & Latham, 1990) and health (Carver & Scheier, 1999), facilitates learning (Frese & Zapf, 1994), and has an energizing (Locke & Latham, 1990, 2002) and attention-directing effect (Carver, 2003), which can promote recovery by promoting mental detachment from work tasks in terms of absence of job-related rumination in leisure time (Sonnentag & Bayer, 2005).
The model proposes that success is promoted by other resources like job control (Frese & Zapf, 1994) while job stressors, like hindrance stressors such as performance constraints and role ambiguity (LePine, Podsakoff, & LePine, 2005), can work against success (Frese & Zapf, 1994). The model assumes reciprocal direct effects of subjective success on well-being, health, and recovery (upward spiral), and a moderator effect of success on the stressor–strain relationship. The chapter discusses research evidence, measurement of subjective occupational success, value of the model for job stress interventions, future research requirements, and methodological concerns.
