  5. Paper Methodology * Collection Analysis Shipment Digitization *Modification of collection not always possible

  6. Paper-based methodology overview • Steps: Printed, completed, shipped, scanned, coded, analyzed • Paper/pencil/hard-copies used for capturing interview and survey data • Data collectors hand write notes during collection phase then type up final files • Hard/soft copies (shipped) to home office for intake then shipped to off-site scanning company • Up to 12,000 pieces of paper produced per country – includes surveys and interviews

  7. Performance and cost Performance • Efficiency – how well it worked • Flexibility – how easy it was to use • Time – how long it took to prepare & deploy Cost • Paper - Printing, shipping, scanning • Digital – Equipment, transmission, support

  8. Field Performance - Digital Efficiency • Reduces (not eliminates) paper/pencil needs • 20,000 sheets of paper and 3000 sharpened pencils needed for Nicaragua • 6 devices in one • Data logger, camera, camcorder, audio recorder, GPS, cell phone • Data assessments, photos and audio automatically tagged and catalogues saves time in intake/cataloguing later • Near real-time security for data as it is transmitted Flexibility • Adjustments made to forms in the field (e.g. adding new schools, new fields to forms, etc 15 – 60 minutes) • Spot checking of data sets as they are collected Time • Instruments formatted for PDAs within a week of receipt • Speeds up data process via scanning (double sided) in the field and not after • 30 - 45 minutes per school (100 student surveys, school/classroom observation forms = 126 sheets of paper)

  9. Field Performance - Paper • Efficiency • Notes on hard copy fast and easy to write • Inputting responses in non-sequential order • Print quality varied – pages omitted, added – effects scanning • Risk of losing data if papers go missing • Flexibility • Sense of security with hard copies • Once printed, modification of instruments must be done manually • Additional equipment needed for cameras and voice recorders • Time • Hard copies had to be received in the field at least 4 days prior to arrival for printing • Needed to be collated for each school prior to each visit • Sent to HO, Scanning Company, Analysis, Reports (4 weeks total after field visit)

  10. Cost - Digital Nicaragua Costs for one week deployment - $8,244 • Equipment - $995 • One Laptop; • Three PDAs; • One BGAN Satellite terminal; • One Scanner • RDMS Licenses for the PDAs and Virtual Network Operation Center • Transmission - $168 • Updating/refreshing instruments as needed • Uploading data sets daily • Accessing VNOC • Support - $7,075 • Prep before the visit • Field 1 person/1 week • Expenses ($1080 – airfare, meals, lodgings) • GRT 24/7 Home office tech support included • Post field support • Two week deployment would be $10,975 plus expenses and additional transmission • Costs will decrease as GRT LOE decreases with increased familiarity with the system

  11. Cost - Paper • Printing • Nicaragua - $790 • Ranges from up to $3,500 (Nigeria) • Suitcases and containers needed • Sharpened pencils required • Shipping • Nicaragua - $0 • To U.S. varies for each country ranging from $0 - $3K • To scanning company ($70/country) • Scanning • Nicaragua - $1,500 • $.58 survey up to 126/school = $73/school or $1,827/country • Includes student, teacher and director surveys • Does not include observation and qualitative data and school records data • Total Cost for Nicaragua - $2,290 • Total Cost Average for UNICEF CFS - $5,827

  12. Value added proposition of Digital • Data Security – Data back-ups start from the first transmission and all data is backed up and secured at AIR Hqs before the project team leaves the country. • Real-time Monitoring Capability – AIR and customer can monitor the progress of the collections effort, validate the integrity of the data and identify issues with regards to collections instruments or collectors while the teams are still in-country. • Flexibility – If an issue with an instrument is identified, data collections forms on the PDA can be dynamically updated via the web to reflect the updated instrument while collectors are still in the field and in country. • Reduction of Logistics Complexities – Use of the PDAs and digitized instruments could significantly decrease logistics complexities and burden associated with a paper based instruments

  13. Conclusions - Digital • Strengths • Changes to research questions (e.g. Architecture to school safety) can happen on the fly to all instruments • Combo of 6 devices in one: GPS tagging schools, cellular/photo capabilities Intake cataloguing and organizing of files is automatic • Rapid, near real-time reporting • Data review while in the field allows for adjustments if needed • Data secured upon transmittal • Can be set to require answers for all or some questions to avoid blank fields • Illegible handwriting avoided • Nearly instantaneous digitization, quasi-analysis and quasi-reporting greatly reduces duration of study • Weaknesses • More conducive to quantitative close ended questions • (multiple choice or number formats are best e.g. number of kids in classroom) • Respondents limited to number of PDAs (100 students surveyed in each school) • Learning and comfort curve required for effective use

  14. Conclusions – Paper based • Strengths • High comfort level • Qualitative/text interface • Weaknesses • Numbers of copies needed not known until at schools • Hard copies must be clean (no “dog ears”), legible and on 60 lb paper for effective scanning • Large/suitcases/water proof containers needed to be purchased for internal transport of hard copies • 135 sharpened pencils required per school (135x25=3,375 average pencils per country) • Changes on the fly difficult to make to instruments (e.g. changing “grupos minorias” to “grupos ethnicos”) – need to be noted and remembered • Handwriting of respondents/data collectors sometimes illegible • Questions sometimes unanswered • Shipping outpost not always available • Data vulnerable to being lost or damaged until digitized • Intake of data was time consuming • Several weeks required for digitization, analysis and reporting
