Business transformation is a key management initiative that attempts to align people, process and technology of an enterprise more closely with its business strategy and vision (Lee, 2005). Business transformation is an essential part of the competitive business cycle. Existing consulting methods and tools do not address issues such as scalability of methodology, data and knowledge management, method enforcement, asset reuse and governance, consolidated views of upstream and downstream analyses well, to name a few. This paper presents Business Transformation Workbench which is a practitioner’s tool for business transformation addressing these problems. It implements a methodical approach that was devised to analyze business transformation opportunities and make business cases for transformation initiatives and thereby provides decision-support to the consultants. The Business Transformation Workbench builds on a component-based model of a business and offers a consolidated view into clients’ operations, organization, staffing, processes and IT. It provides an intuitive way to evaluate and understand various opportunities in staff and IT consolidation and process standardization. It embodies structured analytical models, both qualitative and quantitative, to enhance the consultants’ practices. The Business Transformation Workbench has been instantiated with data from finance management domain and applied to address a client situation as a case study. An alpha testing of the tool was conducted with about dozen practitioners. The feedback has been encouraging. 90% of the consultants who tested the BT Workbench tool felt that the tool would help them do a better job during a client engagement. The tool is currently being piloted with customer engagements in a large IT consulting organization.

Synchromodal transport incorporates real-time events in a dynamic manner in order to facilitate the most suitable selection of modes, routes and handling points. Up until now, current assessments rely on analytical models. Most of these models average distances for barges and trains via route mapping platforms that provide realistic distances for road only. To reflect on real-world developments more accurately, new thinking and modelling approaches are necessary to bridge academic models with physical transport processes. This paper introduces a computational model which computes movements of agents in geographically referenced space. The model captures stochastic parallel processes for each mode, and simulates decentralized delivery performance of each order in terms of cost, time and emissions at an operational level. Furthermore, we study the routing of individual orders and their responsiveness to disruptions. Computational experiments are performed within a case study which concerns imports of retail goods by unimodal truck transport from France to Belgium. Our findings show that dynamic synchromodal solutions cope with disturbances better, but unnecessary deviations and pro-activeness can also lead to negative effects when compared to static intermodal solutions
