Abstract EN:
Flexibility appears as a notion the significance of which is widely acknowlegded: it has been the subject of various and mostly functional approaches. Suggesting a synthetic measure remained to be done in order to make this multidimensional concept operational and check the validity of this measure. Such is subject of the present survey. After showing the interest of the firm flexibility-environment turbulence relation, a theoretical pattern likely to supply an overall measure of flexibility is suggested. This pattern is the subject of an empirical test concerning forty three small and medium size firms representative of aircraft subcontracting in midi-pyrenees. It enables for each of them to obtain a comparative score of potential flexibility at a "t" date. Once the measure is calculated, it is compared to various quantitative as well as qualitative criterions of performance covering a (t+2) - t period. Once the whole there seems to be a positive relationship between the level of flexibi- lity measured by the potential flexibility for "t" and the level of performance registered over the following period for these small and medium size firms with such a turbulent environment. The proposed pattern besides enables to test five suppositions of general
Abstract FR:
La flexibilite est une notion dont l'importance est largement reconnue; elle a fait l'objet de nombreuses approches, le plus souvent fonctionnelles. Il restait a en proposer une mesure synthetique qui rende operationnel ce concept multidimensionnel, et a verifier la validite de cette mesure. Tel est l'objet de la presente etude. Apres avoir montre l'interet de la relation "flexibilite de l'entrepriseturbulence de l'environnement", il est propose un modele theorique susceptible de fournir une mesure globale de la flexibilite potentielle. Ce modele fait l'objet d'un test empirique sur 43 pmi representatives de la sous-traitance aeronautique en midi-pyrenees. Il permet d'obtenir pour chacune d'elles un "score relatif de flexibilite potentielle" (sf) a une date t. La mesure ainsi calculee est ensuite confrontee a differents criteres, quantitatifs et qualitatifs, de performances sur une periode (t+2) - t. Il apparait dans l'ensemble pour ces pmi, dont l'environne- ment est particulierement turbulent, qu'il y a une relation positive entre le niveau de flexibilite, mesure par le sf en t, et le niveau des performances constate sur la periode suivante. Le modele propose permet, en outre, de tester cinq hypotheses de portee generale relatives a la notion de flexibilite. . .
