  • “In Desert Storm, an aerial observer located an enemy unit and sent a bombing request to the artillery headquarters. Using the enemy location’s coordinate received from the artillery headquarters, the Navy ship off the coast fired two rounds, but both missed the target by 527 meters, a distance way greater than expected precision! What went wrong? It turned out that the artillery headquarters and the Navy used different geo-coordinate systems with which the same coordinates represent different locations on earth.” (Zhu & Fu, 2009)“The NASA Mars Climate Orbiter was lost after messages between two different systems were misinterpreted: the first was sending values in US Customary units (lbf-s), the second assumed that the values arriving were measured in SI units (Ns); the result was an initial orbit 170km lower than planned—23km below survivable height” (Davies, Harris, Crichton, Shukla, & Gibbons, 2008). The result: the loss of $125 million. And interoperability problems can be very costly, eg. US automotive industry have additional costs of about $1 billion dollar due to low interoperability (Brunnermeier & Martin, 2002)Triage voorbeeld

    5. 5. WAT IS EEN SEMANTISCHE STANDAARD? Gaat over betekenis van informatie Uitgewisseld door computer systemen (Tussen organisaties) De E-Portfolio standaard! Soort van taal die computers spreken om de uitgewisselde informatie van elkaar te kunnen begrijpen
    8. 8. WAT IS HET PROBLEEM? Puzzelstukjes: De uitwisseling gaat niet optimaal, dat noemen we beperkte interoperabiliteit.  Semantiek is een probleem.  Beschikbaarheid, adoptie en kwaliteit van semantische standaarden. Wat kost dat?  Automobiel industrie VS: 5 miljard  Electro industrie VS: 3.9 miljard  Capital Facilities industrie VS: 15.8 miljard  Zorg VS: 29 miljard (98.000 levens)  Rampen: Volendam ramp
    9. 9. NASA Mars Climate Orbiter After a 286-day journey, the probe fired its engine on September 23 1999 to push itself into orbit. The engine fired as the spacecraft came within 60 km of the planet But that was about 100 km closer than planned and about 25 km beneath the level at which the it could function properly. NASA lost the $125 million spacecraft Mars Climate Orbiter because Lockheed Martin used imperial http://mars.jpl.nasa.gov/msp98/news/mco990930.html http://edition.cnn.com/TECH/space/9909/30/mars.metric.02/ units whilst NASA used metric.Source:http://www.interoperabilityconference.org/microsoft.ppt

    22. 22. UITSTAPJE: QUALITY IN PRACTICE Compleetheid en Relevantie (uit: Quality in Practice) Zhu and Wu: Completeness and Relevance voor XBRL Ui S  Compleetheid: Zit alles er in? Completenessi Ui  Relevantie: Wordt alles gebruikt? Ui S Relevancyi S  Resultaat: Schokkend!
    24. 24. DE RESULTATEN Verrassend en inspirerend!  Completeness and Relevance behoorlijk goed  Zeer waardevolle input voor nieuwe versie van een standaard.  Beroerde implementatie kwaliteit: Wat is de reden? En oplossing? (cursus?)
    25. 25. IQMSS Situationeel ingezet: dus niet het hele kwaliteitsmodel. Niet alles is extreem helder/concreet. Wel gevalideerd (cases / workshops) Garantie op nieuwe inzichten is er! Zelfs voor de meest ervaren standaardisatie-ontwikkelaar.
