The Evolution of the Sahana System, Community and Standards @ Taiwan 2010 The Evolution of the Sahana System, Community and Standards @ Taiwan 2010 Presentation Transcript

  • Evolution of the Sahana System, Community and Standards Sahana Conference 30th July 2010, Taipei Chamindra de Silva SAHANA, Director and CTO VIRTUSA, Head of Strategic Initiatives
  • “In the long history of humankind (and animal kind, too) those who learned to collaborate and improvise most effectively have prevailed” - Charles Darwin
  • Agenda  Before Evolution... Environment?  Sahana System & Community Interaction  Mutation of Sahana so far..
  • Environment: What is a Disaster? “A disaster is a serious disruption of the functioning of a society, causing widespread human, material or environmental losses which exceeds the ability of the affected society to cope using only its own resources” Source:UNDP
  • Some Disaster by Type and Impact
  • A more specific definition UK Home Office Definition: ”Any Event or Circumstance (happening with or without warning) that causes or threatens death or injury, disruption to the community on such a scale that the effects cannot be dealt with by the emergency services, local authorities and other organizations as part of their normal day today activities”
  • The Response Community Disasters Coordination 10s of Orgs 100s of Orgs 1000s – 1 Mill Government Relief UN, NGOs Local Relief Local Authorities, Police, Red Cross, OCHA, CARE, Spontaneous volunteers, Army, Fire fighters, WHO, Sarvodaya, etc corporate village + Authorized coord + focused on people communities, friends and + Well trained + trusted to accept aid family + Accountable +/- less well trained + first responders +/- Big picture relief + accountable + lot of capacity (e.g. national security) - Donor driven + instant aid - Procedures create - narrow focus / fragmented - not trained bottlenecks - sometimes competing - focus unknown - Overloaded - not accountable Effective Collaboration and Coordination! Relief Victims
  • Objectives of Disaster Management  Achieve survival of maximum number of people and suffering of the minimum  Restore essential services ASAP  Restore order to chaos  Inform the public  Coordinate Relief  Provide a foundation for subsequent Recovery
  • Typical Problems Responders have work on..  Search And Rescue  Tracing Missing People  Evacuation  Trauma Counseling  Setting up Shelters  Assuring Security of  Effective Distribution Affected Areas of Aid  Protecting Children  Management of Donars and Donations  Rehabilitation Live saving decisions need to be made very fast! The best decisions are the most informed ones
  • Situation Awareness Defn: “Perception of the environment critical to decision-makers in complex and dynamic situations”  Studies show, lack of SA has been identified as one of the primary factors in accidents attributed to human error (Hartel, Smith, & Prince, 1991; Merket, Bergondy, & Cuevas-Mesa, 1997; Nullmeyer, Stella, Montijo, & Harden, 2005)  Important especially in high information flow, high consequential impact domains (lives at stake)  Air Traffic Control, Military Command and Control, Emergency Response, Disaster Management
  • SA in Emergency Management Well Trained Well defined Responders Information Flows Information Situation Act Awareness Information Decide Well defined Response Process
  • Disaster => Unexpected info Sources  Government & Emergency Services relief capacity has been exceeded or crippled  To match relief capacity boundary of response effort extends to external groups (NGOs, Civil Society, Foreign Aid, UN)  Core Decision Makers need to consult a wider group for better situation awareness  Information has to be gathered from non- traditional “uninitiated” sources for better Situation Awareness
  • SA in Disaster Management Multiple Disparate Information Sources Diverse Responders Information Relief workers, Info Overload Volunteers r ma Large delta tion to reality Information Situation Act Awareness?? Information tio n rma Info Decide n a tio orm Inf Multiple Parallel independent Processes
  • If you were to do it manually 2  Channels N(N-1)/2 = O(N ) 5  Information Lost in relay and propagation 10  Redundant Data Collection 8  Inconsistent Terminology  Manual Collation / 28 Calculation 16  Delayed Situation Awareness 120
  • How Can I.T. Help?  Scalable management of information  No stacks of forms and files to manage  Efficient distribution of information  Accessibility of information on demand  Automatic collation and calculation  No delay for assessments and calculations  Live Situation Awareness  Reports are updated live as data goes in IT Improves Manageability ( I α H x V / M )
  • Thus the Sahana Project  What is it?  A free & open source portable web tool  Sub-applications designed to address the common Disaster Management probs  A RAD platform  Main Goals  Bring Efficiencies to Disaster Coordination and Prompt Response  Facilitate the effective information exchange between responders and beneficiaries  Primary focus is to help victims
  • The Historic Trigger: Tsunami 2004 26 December 2004  At least 226,000 dead  Up to 5 million people lost homes, or access to food and water  1 million people left without a means to make a living  At least $7.5 billion in the cost of damages
  • How Sahana Started Tsunami 2004 Builds Urgent Sri Lanka Urgent Requirements Requirements IT Sahana Community Software IT Community = LSF + LKLUG + IT Industry + Academia
  • The First Community  “We just wanted to help our countrymen”  We used our skills to provide a tool  Operational model - “Chaos”  400 IT volunteers  1st week 24hr development  Major releases almost daily  Applications  Missing Person Registry, Organization Registry, Request management System, Camp Registry
  • They Build it for the CNO
  • Independent Hazard Info. Center
  • Lessons Learned  Surprisingly no one had built such a system before!  The open source community coupled with the humanitarian spirit is a tremendous catalyst for change BUT  NEVER build a disaster management system from scratch during a disaster again!!
  • Inspired the Second Phase of Sahana Proposal Objectives  Build a scalable disaster management sys  Develop Sahana application framework  Develop Initial set of core applications  Make it Open Source and take it global LSF Core team was funded by SIDA for one year
  • Collaborative Virtual Helpdesk zone of trust (legislation)
  • Peer 2 Peer Pony Express
  • Sahana Phase II A Global Need (2005) Builds Requirements Requirements LSF ++SIDA Funds SIDA Funds Team Sahana Phase II FOSS Software LSF Team = “Techies” and FOSS Enthusiasts
  • “Plugin” / Platform Pattern Core Module Core Module New Module New Module Framework and Platform Services  The Plugin / Modular Architecture pattern  Enables evolutionary parallel development  “Survival of the fittest module”  Consistent Base Platform for RAD  Themed UI, Support diverse multiple-clients  Security, Data management, Error handling  GIS, WS, Reporting Toolkits  Eg. Firefox, Symbian, Android, PHP, Eclipse
  • Why we choose LAMP?  (L)AMP – (Linux) Apache MySQL PHP  Free and Open Source end to end  Lightweight (Process and Space)  PHP is easy scripting language to pick up  Rapid “natural” web app development  PHP encourages stateless sessions => horizontally scalable  LAMP Packages: WAMP, XAMPP
  • Who is doing What, Where & When?  Registry of operating relief organizations  Coverage of Services  Self-Allocation and Reporting  Contact Information The Organization Registry helps maintain data (contact, services, region, etc) of organizations groups and volunteers working in the disaster
  • Tracking Missing People / Casualties  Shared Bulletin Board of lost / found  Computer based search heuristics  Tracking Family units  Analyzing networks of connections The Missing People Registry helps track and find missing, people
  • Matching Aid to Ground Realities  Estimating Needs  Matching Aid to Ground Needs  Inventories/Catalog  Quantities  Expiration dates  Re-order levels  Tracking Allocation The Request Management System tracks all requests and helps match pledges for support, aid and supplies to fullfilment
  • Collaborative Situation Mapping Collaborative Map of  Hazards / Incidents  Shelters (IDPs)  (field) Hospitals  Organizations  Responders  Stores  etc The Shelter Registry helps track data on all shelters setup following the Disaster
  • Initial Development Model  Lightweight Software Engineering Project team with Open Source community participation and advocacy REASON  Had to deliver on a timeliness and deliverables of a funded SIDA project  We had to have an initial “complete” app to attract community participation  e.g. Open Office, Mozilla
  • The community + FOSS cycle 2006 Builds & Refines LSF + Global Community Sahana Software Attracts & Grows
  • What is Free and Open Source?  Free as in Speech  Freedom to access, run, modify and redistribute  Open Source  Is a set of principles and practices that promotes access to the design and production of goods and knowledge  Open APIs, Open Code (Blueprints), Open Standards  Regulated by FOSS Licenses  GPL (FSF), LPGL (FSF), Apache (ASF), BSD, CPL  Based on Copyright law, but spun on it's head (copyleft)  Rights are passed perpectually to users  GPL have been proven in court e.g. FSF vs BT  Software is special  Open Source software becomes a global public good
  • Alignment to Humanitarian Values  Freely Available to deploy  No discrimination on access (Red Cross CC #2)  Ability to “leave technology behind” (RC CC #6)  Rapid customization to actual needs with code  L10N and integration (RC CC #5)  Building local capacities & self-reliance (RC CC #6)  Open system => Transparent and trustworthy  Better acceptance than “foreign” proprietary systems  Countries/NGOs can collaborate to develop  Get the best minds from the world to participate in building the software  This should be a global public good  Build on each others work by including it in project Called Humanitarian-FOSS or H-FOSS
  • Other Modules Get Added  Disaster Victim (IDP) Module  Volunteer Management Module  Inventory Management  Evacuation Management  Data Import / Export  Reporting Module
  • Mobile Research POCs + Synchronization USB Disk / Laptop OLPC PDA
  • Phase II later stages and early 2007  Team composition  LSF Core team providing development and regular releases  Global community providing design input and helping to spread awareness  Leadership  Sahana Committee  50% developers and 50% domain experts  “Meritocracy on contribution”
  • It continues.. forged in the fire Incident or Dire Need Builds & Refines Urgent Sahana Urgent Requirements Requirements Community Sahana Software Attracts & Grows
  • Incidents Sahana has responded to  Gov-NADRA, for Asian Quake in Pakistan – 2005  Officially deployed and integrated to NADRA (Pakistan Government) to track all victims  Gov, 3 Disaster in Philippines – 2006  Officially deployment to track all victims with by Philippines Government + pre-deployment  Yogjarkata Earthquake, Indonesia – 2006  Deployed by ACS, Indonesian Reliefsource  NYC prepardness in US – 2007  New york city evacuation management  Gov, Earthquake, Peru – 2007  Gov, Shizuan Earthuake in China – 2008  Deployed by Police to reunite families Sahana Downloaded overs 25,000 times
  • Lessons Learned on Deployment  System should be endorsed and/or authorized by Government (and UN)  IT Literacy and User familiarity  System should be easy to install  If possible pre-deploy and train!  A Sahana local response team is ideal  Local cultural and operational knowledge  Build resilient systems (=> simple, flexible)  Standards are very important for acceptance
  • It continues.. forged in the fire Incident or Dire Need Builds & Refines Urgent Sahana Urgent Requirements Requirements Community Software + Best Practices Attracts & Grows
  • Deployment Model: China Example  Multiple local groups reach out to Sahana  Call out made in Sahana community  One initiative progresses further  L10N / Promotion, QA, Deployment  IBM-China for Chendu Gov and then Police  24x7 Technical Support  LSF, Trinity College, Community Individuals  Funds and Sponsorship  IBM-Foundation  40+ Families reunited within first few days
  • Endorsements and Awards  New Free Software Foundation (FSF) award for “Social Benefit” won and inspired by Sahana  Sourceforge Project of the Month, June 2006  Software 2006, CA USA Good Samaritan Award  One of the top 10 Open Source Project to keep an eye on – Network World article  Recognized by forums such as: − US WSIS, ISCRAM, UNDP IOSN, StrongAngel, AsiaOSS Symposium, Emergency Communications Asia
  • The Community Spreads (2007) An Open Global Community (300+)
  • The 4 Communities of Sahana Free & Open Emergency Source Management Community Community SAHANA Humanitarian Academic Community Research (NGOs) Community
  • Different Perspectives of the elephant “Cool LAMP “Innovative Development but not mature Platform!” EM System” SAHANA “By the “A great Community Research for the POC Community” Platform”
  • PMC and Board is Formed  2007 LSF institutes the PMC and Board  To take Sahana to the next level  Sahana Committee => PMC  Board is appointed by LSF  Open Source and EM Profiles + Some PMC members  This group was given the mandate to take Sahana to the next level
  • Sahana Now  Multiple Projects  Sahana Phase 2 → Sahana Agasti (PHP)  Sahana Eden (Python)  Sahana Mobile (J2ME, Android)  Sahana Standards (W3C, OASIS)  Mission stays the same  One Diverse Community Community
  • System to System Integration  Typically there are multiple systems  How do we get them to work with each other?  Standard  The common language systems use to talk  Examples  CAP, EDXL, TWML, TSO, PFIF  Importance  For better integration and automation  To better future proof your IT infrastructure  To permit an upgrade plan for data
  • Deciding on the right Standards  Factors W3C EIIF XG  Who controls it? for help  Is it an Open Standard? How Open?  How well is it adopted in popular systems?  Is it targetted to our demographic?  Has it being used in the field?  Level of Openess of an “Open Standard”  Royalty Free  Open Process for developing and maintaining standard  Available Open Source implementation
  • Reactive to Proactive improvements Preparedness Projects Builds & Refines F I National L Sahana National Requirements Requirements T E Community Software + R Best Practices Attracts & Grows
  • In Conclusion  Sahana was and continues to be forged in the fire (it keeps it very real)  Sahana Neutral A-Political Solution where ownership is given to the end user  The FOSS benefits align to humanitarian values very well  A diverse community is fundamental to the continued success of the project  Sahana is now more than just Software
  • Take Part in the R-Evolution Join us in taking Sahana to the next level Join the Sahana Community! http://www.sahana.lk
