Scheduling can be considered as short-term production planning that results in a decision-making process that determines how and when production must be accomplished (Alfieri & Urgo, 2015; Herrmann, 2006). This paper is a progress report on the project undertaken at 3B-Fibreglass. The company intends to implement a new scheduling software system in its three plants in Battice (Belgium), in Birkeland (Norway) and in Goa (India). The mission to present a comparative table, which assesses accurately a shortlist of potential solutions, required a project-management methodology. A steering committee was built, as well as a project team, responsible for the day-to-day execution of the project. The strategic problem was defined and its different tasks were planned in the project management manual. The production processes were analysed and outlined in detail via an operations manual that includes the production constraints and their link to the planning task. The functional analysis made it possible to define a precise specification and research the market. Different vendors were met and evaluated based on predetermined performance criteria. Some suppliers were rejected during the project and this report provides recommendations on how to proceed with the implementation. Furthermore, a change-management approach was taken to successfully introduce the change in the organisation. An in-depth analysis of 3B-Fibreglass was performed to align the project with its strategic, organisational and information system environment. Throughout the project, the polyphonic approach has overcome multiple obstacles concerning the process and has promoted a state of mind that is open to change within the company. This paper extensively explains the different steps of the methodology and makes recommendations on how to handle the extension of the project.

The need for establishing a formal limit between the concentration of potentially toxic inorganic compounds in groundwater due to natural processes or to anthropogenic pollution has prompted researchers to develop methods to derive this boundary and define the "Natural Background Level" (NBL). NBLs can be used as screening levels to define the good chemical status of groundwater bodies, as well as to fix the remediation target in polluted sites.The book "Natural Background Levels in Groundwater" brings together a set of case studies across Europe and worldwide where the assessments and identification of this boundary are performed with different methodologies. It provides an overview of the approaches and protocols applied and tested in different states for NBL assessment, ranging from well-known methods, such as component separation or cumulative probability plot methods, to new computer-aided protocols. The main objective of this book is to bring together and discuss different methodological approaches and tools to improve the assessment of groundwater NBLs. The overview, discussion and comparison of different approaches and case histories for NBL calculation can be useful for scientists, water managers and practitioners.
