Towards the Gnularity Theory for Determining the Size of Atomic Method Fragments for Use in Situational Method Engineering

1. Towards the use of granularity theory for determining the size of atomic method fragments for use in situational method engineering Brian Henderson-Sellers Director, COTAR Centre for Human Centred Technology Design School of Software University of Technology, Sydney Cesar Gonzalez-Perez The Heritage Laboratory CSIC, Santiago de Compostela

6. Abstraction Mapping α : S  A Formally, an abstraction maps between two formal systems, Σ 1 , Σ 2 , where each system is a set of formulae, Θ , written in a language Λ . Then, equating Θ with Λ (Giunchiglia and Walsh, 1992), we have Σ =( Λ ) such that f: Σ 1  Σ 2 and f Λ : Λ 1  Λ 2

8. Granularity abstraction called F-ABS by Keet (2007)  

10. Example: Granularity in classification/instantiation structure Class Object detail added detail removed

11. Proposed size measure (ER2010) G s = 1 G s = 0.2

13. Methodology metamodel triangle Here, we focus on WorkUnit
