Improving Requirements Engineering within the European Space Industry

International audienceThe Next Generation Requirements Engineering (NextGenRE) (ESA/ESTEC Contract 4000101353/10/NL/SFe) project seeks to identify possibilities to improve the requirements engineering process within the European Space industry in connection with Model-based System Engineering (MBSE)

Configuration management plan. System definition and project development. Repository Based Software Engineering (RBSE) program

This is the configuration management Plan for the AdaNet Repository Based Software Engineering (RBSE) contract. This document establishes the requirements and activities needed to ensure that the products developed for the AdaNet RBSE contract are accurately identified, that proposed changes to the product are systematically evaluated and controlled, that the status of all change activity is known at all times, and that the product achieves its functional performance requirements and is accurately documented

The Impact of Changing Requirements

The fundamental purpose of an Engineering Change Proposal (ECP) is to change the requirements of a contract. To build in flexibility, the acquisition practice is to estimate a dollar value to hold in reserve after the contract is awarded. There appears to be no empirical-based method for estimating this ECP withhold in the literature. Using the Cost Assessment Data Enterprise (CADE) database, 533 contracts were randomly selected to build two regression models: one to predict the likelihood of a contract experiencing an ECP, and the other to determine the expected median percent increase in baseline contract cost if an ECP was likely. Results suggest that this two-step approach works well over a managed portfolio of contracts in contrast to three investigated rules-of-thumb. Significant drivers are the basic contract cost and the number of contract line items

Introduction of a Target Cost Mechanism in one of the LHC Civil Engineering Contracts

Since February 1997 when the four main engineering contracts were issued to prospective bidders there have been many changes to the CERN requirements associated with civil engineering. The contract associated with the LHC machine (T054) has been the one most disrupted by these changes, many of which have come about as a result of the later than anticipated delivery of the Déclaration d'Utilité Pubique (DUP) from the French Government. This has led to all contractual dates being changed and significant acceleration of the works being instructed. This paper discusses a mechanism that has been introduced into the contract that enables all parties to work together in order to minimise the cost of these changes. The mechanism, which is based on a Target Cost, enables the contractor to obtain financial benefit from reducing the overall cost to CERN
