ReFrame Design Review 2 | May 11, 2006 William Croisettier, Sarah Stein Greenberg, Gustavo Romero, Jin Tsubota

Big Idea | Build a Better Pump Frame “This is an important design challenge we have. Frames are crucial to every single user!” – Jim Taylor, IDE|m BAMBOO When there’s a problem with the frame it lowers the water yield by about 130 gallons an hour, a 15% efficiency loss Adds to wear and tear on the pump (hold up rubber washer) WOODEN IDE FRAME (METAL)

Early Design Directions Mobility Height

Current User Complaints | Workarounds Too expensive Not adjustable Treadles too short Handle too far forward Counterweights Height of pump Unstable Over 54% of metal frame customers complained about the treadle length in the early customer care survey, but only ~4% of wooden frame users

The Customer “Stavros”

Customer Choice Buy wooden frame… $8 – 15 OR Buy metal frame… $15 OR Make my own frame… On TOP of the cost of the pump Remind audience that for someone who makes less than a dollar a day, a difference of $5 or $7 is significant, especially when you consider the 10-15% MONTHLY interest rates on borrowing money in Myanmar The majority of pump users do NOT buy IDE’s metal frame 50% wooden | 30% IDE’s metal frame | 20% bamboo or other

the “MyanMyFrame” Introducing Value Proposition Core Principle | improved frame at an equal or better price than current options that allows the customer to choose the right mix of cost and convenience More stable than any existing option More customizable than any existing option Efficiency upgrade for people who are making their own frames Cheaper alternative to carpenter-made wood frames & IDE’s metal frames

Design Concern | The DIY-OTS Continuum “Just Joints” Hybrid Materials Welded or Pre-Assembled Wood Do it Yourself (DIY) Off-the-Shelf (OTS) Some Assembly Required Customer’s skills Customer’s access to tools Customer’s access to materials Price sensitivity Perception of durability Still considering whether to go with ONE product or several Issues

Welded or Pre-Assembled Wood Some Assembly Required Prototypes “Just Joints” Hybrid Materials Welded or Pre-Assembled Wood Do it Yourself (DIY) Off-the-Shelf (OTS) Some Assembly Required < $8 $8 - $15 $15 Same design but varying levels of assembly. Introduce Will to show prototype

Central Design Problem Prototypes Same design but varying levels of assembly. Introduce Jin to show prototype Central Design Problem How to connect bamboo or wood pieces with the steel frame components?

Organizational Plan No separate organizational structure Be a “pilot project” for establishing the Extreme Affordability class as a feeder for new IDE products Obtain seed capital for additional R&D costs from philanthropic sources Sarah goes to Myanmar this summer to support this process Add the MyanMyFrame to IDE’s product line by October 2006

Financial & Organizational Considerations We are obtaining detailed cost information on materials (steel, wood, bamboo, rope…etc.) 50% of cost of current pump is from steel angle irons and square tubes – what can we eliminate while retaining or enhancing structural stability? The MyanMyFrame will (hopefully) replace local carpenters’ frames: will there be an effect on vendor/dealer relationships? Materials are not uniformly available throughout the country – should IDE sell the wood/bamboo inserts? IDE workers are welders, not carpenters…if the MyanMyFrame requires wooden parts, not metal, will it be difficult to start this new product line? Introduce Gustavo here?
