By modelling an organizations business processes, it is possible to capture how the organization coordinates the work and resources with the aim of achieving its goals and strategies (Sharp, et al., 2001). Since business processes and goals are intrinsically interdependent, establishing an alignment between the process and the goal domains arises as a natural approach. This thesis reports on a real-life exploratory case study in which we investigated the relationship between the elements of the enterprise (modeled in the ARIS framework) and the goals (modeled in the Tropos framework and modeling language) which are attained by these elements. The case study has been conducted in the Rheumatology Department of a University Hospital in Brazil. In the course of the case study, we have identified the need of splitting this effort into three phases: the elicitation phase (in which goal models and business process models are captured from the organizational domain), the harmonization phase (in which the goal domain is structured for alignment according to the business processes structures that will support it) and the alignment phase (in which the relationships between the goal domain and the elements of the organizational domain are established). In order to investigate the relation between goals and enterprise elements, we propose an ontological account for both architectural domains. We recognize the importance in considering the business process as the means for implementing an enterprises strategy, but we do not exclude the remaining enterprise elements. Furthermore, we are concerned with both the identification of the relationships and with a classification for their nature.

Thesis (MScEng (Industrial Engineering))--University of Stellenbosch, 2010. / ENGLISH ABSTRACT: Concurrent and distributed business processes are becoming the norm in many organisations. Current modelling techniques do not address the problems faced by concurrent business processes sufficiently. We showhowmodel checking is applied to business processes to prove behavioural properties to address the aforementioned shortcomings. A method of abstraction is required to construct business process models that can be model checked. In this thesis we show the suitability of the Logical Thinking Process as an abstraction tool. We call the combination of the Logical Thinking Process and model checking the Complexity Alleviation Method (CAM). We apply CAM to two well-known supply chain and manufacturing problems, and insightful results are obtained. This leads us to the conclusion that CAM allows for the quicker modelling of business processes, as well as providing problem-specific and proven solutions in amanner not possible with simulation or other techniques. / AFRIKAANSE OPSOMMING: Gelyklopende en verspreide besigheidsprosesse word ’n alledaagse verskynsel in menigte instansies. Huidige modelleringstegnieke is nie in staat om die probleme geassosieer met gelyklopende besigheidsprosesse aan te spreek nie. Ons wys hoe model model verifikasie (“model checking”) toegepas word op besigheidsprosesse om gedragseienskappe te bewys en sodoende die voorgenoemde tekortkominge aan te spreek. ’nMetode van abstraksie word benodig ombesigheidsprosesmodelle, wat verifieerbaar is, te konstrueer. In hierdie verhandeling word die geskiktheid van die Logiese Denkproses (“the Logical Thinking Process”) as abstraksie gereedskap aangetoon. Ons noem die kombinasie van die Logiese Denkproses en model verifikasie Kompleksiteitsverligtingsmetodologie (CAM). Ons pas CAM op twee welbekende aanbodketting- en vervaardigingsprobleme toe en insiggewende resultate is verkry. Dit lei ons tot die gevolgtrekking dat CAM vinniger konstruering van modelle te weeg bring, sowel as probleem spesifieke en bewysbare oplossings verskaf wat nie moontlik ismet simulasie of ander tegnieke nie.

This bachelor thesis deals with the subject of business process modelling in an outsourced environment. The communication process between two parties that are on either side of the globe can be problematic and affect the quality of the system requirements. The background of this study is that there is a lack of communication between these parties, which will eventuate in poor results.   The purpose of this study is to find out whether it is possible to make use of business process modelling in an outsourced environment in order to increase the quality of system requirements by bringing the two parties closer together with help of a common language. A qualitative approach was used to interview relevant informants at Länsförsäkringar AB and its business units Länsförsäkringar Liv and Länsförsäkringar Bank.   We have identified that it is not necessarily the system requirements that have a poor quality but how these system conveyed to the external supplier. Based on our data collection, we realized the great benefits of business process modelling as a means of communication in the system development, which can be a huge advantage in an outsourced environment. According to our study, it is certain that a business process modelling with mapped processes and flow charts can support communication as a common language because of the creation of processes and images instead of text.

Business processes are essential instruments used for the coordination of organisational activities in order to produce value in the form of products and services. Information security is an important non-functional characteristic of business processes due to the involvement of sensitive data exchanged between their participants. Therefore, potential security shortfalls can severely impact organisational reputation, customer trust and cause compliance issues. Nevertheless, despite its importance, security is often considered as a technical concern and treated as an afterthought during the design of information systems and the business processes which they support. The consideration of security during the early design stages of information systems is highly beneficial. Goal-oriented security requirements engineering approaches can contribute to the early elicitation of system requirements at a high level of abstraction and capture the organisational context and rationale behind design choices. Aligning such requirements with process activities at the operational level augments the traceability between system models of different abstraction levels and leads to more robust and context-aware operationalisations of security. Therefore, there needs to be a well-defined and verifiable interconnection between a system’s security requirements and its business process models. This work introduces a framework for the design of secure business process models. It uses security-oriented goal models as its starting point to capture a socio-technical view of the system to-be and its security requirements during its early design stages. Concept mappings and model transformation rules are also introduced as a structured way of extracting business process skeletons from such goal models, in order to facilitate the alignment between the two different levels of abstraction. The extracted business process skeletons, are refined to complete business process models through the use of a set of security patterns, which standardise proven solutions to recurring security problems. Finally, the framework also offers security verification capabilities of the produced process models through the introduction of security-related attributes and model checking algorithms. Evaluation of this work is performed: (i) through individual evaluation of its components via their application in real-life systems, (ii) a workshop-based modelling exercise where participants used and evaluated parts of the framework and (iii) a case study from the public administration domain where the overall framework was applied in cooperation with stakeholders of the studied system. The evaluation indicated that the developed framework provides a structured approach which supports stakeholders in designing and evaluating secure business process models.

Information demand is a part of comprehensive business logistics which encompass logistics of information. The demand for information has provided a unifying framework for different needs on enterprise modeling. Hence, the problems organizations faces relating to flow and distribution has lead to the development of various framework for analyzing information demand and this is guided by a set of rules, methods and even a unified representation. This thesis work defines a specification for enterprise Information Demand Context model using XPDL as the language of construct. The paper gives reasons why XPDL was preferred for such a representation and show how mapping is carried out from the constructs of notations to its associated XPDL specifications, so that when we are defining a representation we are as well defining its meta model. The resulting specification is presented in such a way that it should be able to give a flexible, logical and more defined structure.

Problems of requirements which are identified in the earlier phase of a software development project can deeply affect the success of the project. Thus studies which aim to decrease these problems are crucial. Automation is foreseen to be one of the possible solutions for decreasing or removing some of the problems originating from requirements. This study focuses on the development and implementation of an automated tool that will generate requirements in natural language from business process models. In this study, The benefits of the tool are discussed, and the tool is compared with other software requirement s related tools with respect to their functionality. The developed tool has been tested within a large military project and the results of using the tool are presented.

The graphical modelling of processes is of growing popularity and high relevance to organisations that seek to document, analyse and improve their business operations. This research investigates the phenomenon of continued user acceptance of the grammars that are used to build process models. It develops and tests a theory that can be used to explain and predict why users would opt to continue working with certain grammars in their process modelling efforts. This study builds on established theories, including the Technology Acceptance Model, Expectation-Confirmation Theory, Task-Technology Fit Theory and Representation Theory. These theories suggest that end users typically strive for tools that are useful and easy to use, which confirm their expectations through firsthand utility, and which match task requirements and individual abilities. Representation theory suggests that modelling grammars should be complete and clear in their capabilities to represent real-world domains. The research model has been designed by combining conceptual studies of acceptance and continuance theories with a representational analysis of the BPMN grammar, which is a recently ratified industry standard for process modelling and thereby of high practical relevance to process modelling practice. It further incorporates findings from nineteen semi-structured interviews with process modellers in Australia. The research model has been tested and validated by means of a web-based survey with 590 process modellers world-wide. This thesis contributes to the body of knowledge in a number of ways: First, it presents an empirically validated model of the factors determining a user's intention to continue using a process modelling grammar. Second, it measures the impact that grammar characteristics as well as user and task characteristics have on user evaluations of a process modelling grammar. Third, it presents empirical evidence on the consequences that perceived representational deficiencies entail on user perceptions of a process modelling grammar.

Sales are a subject that most people consider to be an art. The truth is that there are several sophisticated methodologies on how to successfully close a deal. However, time goes by, customers get smarter and the markets shifts. As a result sales methods start to fade away and do not necessarily work the way they used to. This thesis was conducted in co-operation with SimCorp A/S and aims to examine the concept of Insight Selling. The concept was developed by analysing top performers and how they manage to sell in an economic downturn. The purpose is to investigate how an organisation can apply the core principles of the new sales strategy on an existing sales process and current customer relationship management system. A qualitative research method was used and interviews were conducted to gather data to gain a deeper understanding on the topic of sales. The result exhibits a situation analysis that was conducted to create a representation of SimCorp’s current sales process. With the key elements of insight selling a proposed model of a future state was presented. Lastly, a requirements analysis of the customer relationship management system currently deployed at the company was designed based on the findings. The result indicated that it was possible to apply the key elements of insight selling on the current sales process. The method might be suitable for some situations but it does not replace or eliminate earlier practices. / Det är vanligt att uppfatta försäljning som en konst. Sanningen är att det finns väl beprövade metodiker för hur man ska lyckas för att sälja. Med tiden har konsumenter blivit smartare och marknaden förändrats. Detta har resulterat i att många säljmetoder blir avlägsna och inte lika användbara och pålitliga som de var innan. Examensarbetet utfördes i samarbete med SimCorp A/S där syftet är att undersöka begreppet insiktsförsäljning. Konceptet utvecklades från en studie där man analyserade de högpresterande säljarna och identifierade hur de lyckades sälja under en ekonomisk lågkonjunktur. Syftet är att undersöka hur en organisation kan applicera de nya strategierna som presenteras inom insiktsförsäljning på en befintlig försäljningsprocess och det nuvarande kundhanteringssystemet. En kvalitativ forskningsmetod applicerades och intervjuer utfördes för att ackumulera data och få en djupare förståelse av ämnet försäljning. I resultatet presenteras en nulägesanalys av SimCorp’s nuvarande försäljnings-process. Vidare presenteras ett förslag på hur en försäljningsprocess med inslag av strategierna från insiktsförsäljning kan se ut. Slutligen utfördes en kravanalys på insiktsförsäljnings metod för att implementeras och testas på det nuvarande kundhanteringssystemet. Resultatet indikerade att det var möjligt att applicera nyckel elementen från insiktsförsäljning på den nuvarande säljprocessen. Metoden är lämplig för att användas i vissa situationer men ersätter inte eller eliminerar tidigare rutiner.

Knowledge is considered important for the survival and growth of an enterprise. Currently knowledge is stored in various places including the bottom drawers of employees. The human being is considered to be the most important knowledge provider. Over the years knowledge based systems (KBS) have been developed to capture and nurture the knowledge of domain experts. However, such systems were considered to be separate and different from the traditional information systems development. Many KBS development projects have failed. The main causes for such failures have been recognised as the difficulties associated with the process of knowledge elicitation, in particular the techniques and methods employed. On the other hand, the main emphasis of information systems development has been in the areas of data and information capture relating to transaction based systems. For knowledge to be effectively captured and nurtured it is necessary for knowledge to be part of the information systems development activity. This thesis reports on a process of investigation and analysis conducted into the areas of information, knowledge and the overlapping areas. This research advocates a hybrid approach, where knowledge and information capture to be considered as one in a unified environment. A meta-schema design based on Formal Object Role Modelling (FORM), independent of implementation details, is introduced for this purpose. This is considered to be a key contribution of this research activity. Both information and knowledge is expected to be captured through this approach. Meta data types are provided for the capture of business rules and they form part of the knowledge base of an organisation. The integration of knowledge with data and information is also described. XML is recognised by many as the preferred data interchange language and it is investigated for the purpose of rule interchange. This approach is expected to enable organisations to interchange business rules and their meta-data, in addition to data and their schema. During interchange rules can be interpreted and applied by receiving systems, thus providing a basis for intelligent behaviour. With the emergence of new technologies such as the Internet the modelling of an enterprise as a series of business processes has gained prominence. Enterprises are moving towards integration, establishing well-described business processes within and across enterprises, to include their customers and suppliers. The purpose is to derive a common set of objectives and benefit from potential economic efficiencies. The suggested meta-schema design can be used in the early phases of requirements elicitation to specify, communicate, comprehend and refine various artefacts. This is expected to encourage domain experts and knowledge analysts work towards describing each business process and their interactions. Existing business processes can be documented and business efficiencies can be achieved through a process of refinement. The meta-schema design allows for a ?systems view? and sharing of such views, thus enabling domain experts to focus on their area of specialisation whilst having an understanding of other business areas and their facts. The design also allows for synchronisation of mental models of experts and the knowledge analyst. This has been a major issue with KBS development and one of the main reasons for the failure of such projects. The intention of this research is to provide a facility to overcome this issue. The natural language based FORM encourages verbalisation of the domain, hence increasing the understanding and comprehension of available business facts.

The topic of this thesis is the process analysis of the production company. The main goal is to describe, model and asses the recent status of processes. The additional goal is the measurements and recommendations proposal based on the evaluations. The process management is described in the introduction of the theory with subsequent explanation of methods and methodology of process modeling. The basic standards for process models creation is described in the next part of the thesis. The analyzed company will be introduced in the practical part of the paper and the method derived from the theoretical part will be applied. After modeling the recent status the necessary measures and changes will be introduced to eradicate the identified problems.
