This paper takes a practitioner’s perspective on the problem of organisational decision-making. Industry practice follows a refinement based iterative method for organizational decision-making. However, existing enterprise modelling tools are not complete with respect to the needs of organizational decision-making. As a result, today, a decision maker is forced to use a chain of non-interoperable tools supporting paradigmatically diverse modelling languages with the onus of their co-ordinated use lying entirely on the decision maker. This paper argues the case for a model-based approach to overcome this accidental complexity. A bridge meta-model, specifying relationships across models created by individual tools, ensures integration and a method, describing what should be done when and how, and ensures better tool integration. Validation of the proposed solution using a case study is presented with current limitations and possible means of overcoming them outlined.

Modern business systems need to cater to rapidly evolving business requirements in an ever-shrinking window of opportunity. Modern business systems also need to keep pace with rapid advances in technology. Model- driven development approach addresses these issues by separating the technology concerns from functionality by providing a set of modeling notations for specifying different layers of a system namely user

We discuss our experience of using model-based techniques to generate model-based code generators. The central idea behind model-driven development (MDD) is to use suitable models to specify various concerns and transform these models to a variety of text artifacts. A business product needs to deliver a given business functionality on a wide variety of implementation platforms and architectures thus necessitating

We discuss our experience in using model-driven techniques to build large business applications on a variety of architectures and technology platforms. Our foray into model-driven techniques began 12 years ago when our organization decided to develop a banking product that was to be capable of being delivered on multiple technology platforms and capable of easily keeping pace with technological advances.

Cost estimation studies in model-driven engineering (MDE) are scarce; first, due to difficulty in quantifying qualitative characteristics of MDE that supposedly influence software development effort and second, due to the complexity of measuring varied artifacts that are generated and used in an end-to-end MDE toolset. A cost estimation approach is therefore needed that can incorporate characteristics of MDE that affect

ABSTRACT With continued increase in business dynamics, it is becoming increasingly harder to deliver purpose-specific business systems in the ever-shrinking window of opportunity. Code-centric software product line engineering (SPLE) techniques show unacceptable responsiveness as business applications are subjected to changes along multiple dimensions that continue to evolve simultaneously. Through clear separation of functional concerns from technology, model-driven approaches enable easy delivery of the same functionality into multiple technology platforms. However, business systems for same functional intent tend to have similar but non-identical functionality. This makes a strong case for bringing in SPLE ideas i.e., what can change where and when, to models. We propose an abstraction that aims to address composition, variability and resolution in a unified manner; describe its model-based realization; and outline the key enablers necessary for raising business application product lines. Early experience of our approach and issues that remain to be addressed for industry acceptance are highlighted.

There are signs that cost arbitrage model of outsourcing engagement between enterprises and service providers will have to change to one based on value generation. Automation decisions taken by siloized businesses under cost arbitrage models have led to complex cost-ineffective situations. Both these situations may be addressed by an innovative business model based on product family concepts that systematically targets

Taking and executing correct decisions is critical in enterprise systems which are characterized by rapid changes along interconnected dimensions. Enterprise architecture (EA) frameworks offer holistic treatment of enterprise systems but constitute only one part of the solution to problems arising due to organizational changes. The other, less explored part is the ability to explicate and analyze the intentions behind major decisions. We investigate a step-by-step approach where intentional modeling is treated as a problem solving technique. In our approach, an intentional model devoid of goals is obtained from the existing EA model via mapping. It is expanded by representing the problems due to organizational changes as goals and soft goals and alternative solutions to them. The final intentional model is transformed back to an actionable EA model via the same mapping. In the case study, we re-imagine the evolution of our model-driven software develop- ment unit as an enterprise whe...

The demand for integrating enterprise applications is growing as a consequence of the need to support dynamic, cross-functional and inter-organizational business processes. Traditional organization of an enterprise as a set of functionally distinct departments leads, over a time, to a set of isolated applications providing point solutions each constructed for a specific purpose. Enterprise Application Integration (EAI) discipline deals with mechanisms for putting these isolated applications together. By visualizing an enterprise application as a 3- tuple comprising of its data, service and process models, EAI problem can be visualized as a view-integration problem over data, service and process models. Semantic underpinnings of the high level notations used by Industry practice to specify the process model of enterprise applications, and tools and techniques prevalent in EAI practice are not rich enough to capture and verify the behavioral aspect of enterprise application with rigor...
