  5. Pilot stage of the Geoportal – the traditional approach • The FinnishGeoportalpilotwasbuiltduring 2009 using a traditionalrequirement-basedprocess • thoughbasedcompletely on OpenSource software: • Partnersurveys and analysis of whatfunctionality is neededwere made • Detailedrequirementsspecificationwaswritten • A biddingprocesswasstarted and a consultancycompanycontracted to deliver the definedGeoportal • The definitionswerehandedover to the consultant NATIONAL LAND SURVEY – DOWN TO EARTH

  6. Problems with the traditional- 1 • Partner surveys and analysis of what functionality is needed? • It was not possible to capture all requirements at the same time despite of repeated surveys and analysis • Detailed requirements specifications? • It proved nearly impossible to write an accurate requirements specification for the entire duration of the project NATIONAL LAND SURVEY – DOWN TO EARTH

  7. Problems with the traditional- 2 • Biddingprocess and consultancycompanyselection for delivery? • The competence of the consultantwasassessedmostlybased on references and the projectplanprovided • Definitionshandover? • Itwasnotproperlyensured, that the consultant and the customershare a common understanding of the expectedresults NATIONAL LAND SURVEY – DOWN TO EARTH

  8. Problems with the traditional- 3 • Results • Despite the communicationduring the developmentprocess • Resultedfunctionalitynotaccording to specifications • Somespecificationshadbeenmisinterpreted • Difficult to control the overallquality • ..and as a final Bonus: • The agreementwith the consultantsomewhatlimited the usage of the OS codedeveloped General dissatisfaction and piles of unnecessarywork.. NATIONAL LAND SURVEY – DOWN TO EARTH

  9. Conclusion - The AgileWay • ChooseAgilemethods* for development (scrum) • Payattention to the biddingprocedure • Involve the partners in the process • Fullyexploit the benefits of OpenSource *http://en.wikipedia.org/wiki/Agile_software_development NATIONAL LAND SURVEY – DOWN TO EARTH

  14. The Agile Way - 1 • ChooseAgilemethods for development • TaskDefinitionsarewritten in form of a ProductBacklogwhichevolvesthroughout the entireproject • Resultsaredemonstratedaftereachsprint – new functionalitye.g. every 2 weeks • Continuoustesting - mistakesorwrongchoicesyoumakewill show upsoon • The priorisationprocessensures the critical and mostcost-beneficialfunctionality is implementedfirst (80/20 rule) • Sense of control of the projectthroughconstantprogressmonitoring NATIONAL LAND SURVEY – DOWN TO EARTH

  15. The Agile Way - 2 • Payattention to the biddingprocedure • Identify the keycompetencesrequired for producing the outcome • Evaluate the competence of candidatedevelopers – actuallyyouhire the resources for software development • Developerswillingness to currentdevelopments - OS software is constantlydeveloping • Considerhaving the programmersworkat/nearbyyourlocation (hiredresource) • The resultingcode to bereleasedunderOpenSourcelicense NATIONAL LAND SURVEY – DOWN TO EARTH

  16. The Agile Way - 3 • Involve the partners in the process • Gatheruserrequirementsconstantly • Useyourpartners as testers • Makeit a jointventure”This is our common Geoportal” • CreateWin-Winbenefits”IfyouopenyourView Service, I’llprovideyouwith an embeddedmapservice” • Make sure partnerssee the benefitstheywillget – continuouscommunication NATIONAL LAND SURVEY – DOWN TO EARTH

  17. The Agile Way - 4 • Fullyexploit the benefits of OpenSource • Ensureliberallicensingpolicy in the consultancyagreement • Distributeyoursourcecode – ”Codedevelopedusingpublicfundsshouldbepublic”! • Contribute to the OS community (establishown OS group as necessary) for sustainablity • Seekjointprojectswithorganisationswithsimilarneeds for developing new features • Utilize common components and platforms NATIONAL LAND SURVEY – DOWN TO EARTH

  18. The outcome • Goodquality • Time and effortnotwasteddue to continuoustesting, regular ”checkpoints” and releases • Benefits to the whole SDI in form of • Readilyapplicable OS components • AcceleratedNetwork Service availability • Costsavings, efficientuse of Public Sector money • Satisfiedpartners, management AND developers NATIONAL LAND SURVEY – DOWN TO EARTH

  19. ..But don’t forget to: • Make sure the overallgoal (Vision) is crystalclear • Plan the architecture in advance • Choosetechnologies and developmentprinciples • Allocateresources for Userinterface and Usabilitydesing as well as continuoustesting • Usecollaborative & communicationstools, such as Wiki, Jira, Skype… • Allocateenoughtime for project management, especially for ProductBacklogmaintenance Commit yourself and others to the project! NATIONAL LAND SURVEY – DOWN TO EARTH

  20. More OS sources to apply, e.g.: • http://wiki.osgeo.org/wiki • http://community.esdi-humboldt.eu/ • The HUMBOLDT GeoModel Editor, which you can use to develop rich Conceptual Models for your geodata. • The HUMBOLDT Alignment Editor, an application that helps you map and transform complex database and application schemas • The Workflow Design and Construction Service, a web service that delivers executable geoprocessing workflows for data harmonisation • The Conceptual Schema Translation Service, a Web Processing Service for transforming data from one application schema to another • The Edge Matching Service, a WPS that deals with inconsistencies in geometry
