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

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

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

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?

Standardisation and Differentiation in Redesigns 12
• 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

Support: kennR! (knowR!)
• Training, consulting: [email protected], Wiki • User meetings• Standards:
• Coding standard • Software developement standard
• Deployment of Methodology Series in R

Standardisation and Differentiation in Redesigns 14
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

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
