1. Standardisation and Differentiation in Redesigns Focussing on Redesign Approach, Standard Toolbox and the Introduction of R (case) Frank Hofman

2. Standardisation and Differentiation in Redesigns 1 Content Context Standardisation & Differentiation Redesign Approach & Documents Standard Toolbox Case: Introduction new tools – R Discussion & Questions

3. Standardisation and Differentiation in Redesigns 2 Context Challenges Improve efficiency Improve quality Lower administrative burden Measures Reuse: data, methodology, processes, IT-systems Standardisation

7. Standardisation and Differentiation in Redesigns 6 Redesign approach (1) Aim: support redesign projects Benefits: Projects start up more efficient Project results better comparable Adoption of standards like RUP and Prince Templates for all documents Process simular for large and small projects, but documentation scaled down

9. Standardisation and Differentiation in Redesigns 8 Standard Toolbox Aim: Offer max. functionality with min. set of tools Usage: Development in small, self-supporting projects Ad hoc analysis Methodological research Benefits: Reduce maintenance and license costs Reduce development costs Easier integration of tools Wider knowledge  better reliability

10. Standardisation and Differentiation in Redesigns 9 Governance of Standard Toolbox For each tool: Clear responsibilities (e.g. functional en technical maintenance) User support: training, consultancy Standards & guidelines Toolbox: stable, but not fixed  Lifecycle management

11. Standardisation and Differentiation in Redesigns 10 Case: Introduction of R Statistical software environment & language Functionality: flexible, statistical functions and graphical analyses Easy, compared to traditional PL’s For data processing Open source & worldwide standard Modularity: packages  standard components What is R?

12. Standardisation and Differentiation in Redesigns 11 Development of production systems by statisticians (self-supporting projects) Statistical research: incidental data analysis R&D tool for methodologists In research projects Development of standard packages  for direct use in production Exchange with other NSI’s R at Statistics Netherlands

14. Standardisation and Differentiation in Redesigns 13 Summary Standardisation helps to promote reuse Redesign approach helps applying standards Standard toolbox for self-supporting projects R is powerful statistical tool that also enables development of standard components for use in self-supporting projects

15. Standardisation and Differentiation in Redesigns 14 Discussion points Standardisation is a necessary condition for further cooperation between NSI’s European standardisation: Central development or adoption of local standards Experiences with way of working in redesign projects Cooperation in development R packages
