Improving data quality in a process documentation system : requirements and benefits; a case study
Tämän tapaustutkimuksen tavoitteena oli selvittää kuinka datan laatua voitaisiin mitata ja kehittää prosessidokumentaatiojärjestelmässä. Dataa kerättiin
olemassa olevaa dokumentaatiota tutkimalla, sekä kyselyn avulla. Datan laatu
ei ole aiemmin saanut juurikaan huomiota tässä kontekstissa, minkä johdosta
täysin uudet metriikat datan laadun mittaamista prosessidokumentaatio järjestelmässä varten luotiin tämän tutkimuksen aikana. Tutkimuksen aikana tunnistettiin kolme laatumittaria, askeleet datan laadun kehittämistä varten esiteltiin, ja vaatimukset datan laadun kehittämiselle määriteltiin. Datan laadun lähtötaso määriteltiin metriikoiden perusteella ja vaatimukset ja toimenpiteet kehitykselle määriteltiin. Vaatimusten perusteella myös mahdolliset hyödyt ja kustannukset kyettiin arvioimaan This case study was aiming to find how data quality could be measure and improved in a process documentation system. Data was gathered using existing
documentation and a survey. Data quality has not previously seen much focus
in this context, and therefore new metrics for measuring data quality in a process documentation system were created. Three different quality metrics were
identified during this study, steps for data quality improvement were proposed
and basic requirements for improving the quality were set. The current data
quality level was defined based on the created metrics and ways to improve it
were identified. Based on the requirements for the improvement work, potential costs and benefits that the data improvement work could cause were also
listed
