Re-design SPPI The Netherlands M. Spanjaard, PhD
Outline • Introduction • Production process • Sampling • Classification • “Pricemethods” • Comments
Introduction (1) • 10 people working on SPPI (~9FTE) • 23 branches
Introduction (2) • Re-design • efficiency • quality
Production process[old] • realised hourly rates: diff > 10% • modelpricing: diff > 5% • not efficient
Production process[new] • Topdown Tool • Only contact companies which have a significant influence on the indexmutation
Sampling[old] • stratum based on # of employees • (not on turnover!) • Fixed company weights • updated around every 5 years
Sampling[new] • PPS method • based on turnover • Census part • Sample part
top level of industry Freight Transport by Road Freight Transport by Road Moving services sub level B C A B A A lowest level / activities (CPA) bulk liquids or gases frozen or refrigerated goods petroleum products activities from companies
Classification[old] • NACE Rev 1 • Detailed level based on “own industry” • not CPA!
Classification[new] • NACE Rev 2 • Detailed level based on CPA • uniformity • sampling • EuroStat obligation
“Pricemethods”[old] • Unit values / realised hourly rates • Not a good pricingmethod for most industries • The re-design project “pricemethod” was not structured
“Pricemethods”[new] • Modelpricing • quality change • Organised re-design “project pricemethod” • 1- Initial research • 2- Company visits • 3- Pricing method proposal • 4- Method testing on subsample • 5- Analysis of results • 6- “In production”
