Sudha has just passed her class XII with 90% marks and was to start her own business but was unable to decide about the nature of business. Her friend, Sumita suggested her to seek professional help.

One day during the morning walk her grandmother fell down in park. She observed that her grandmother often forgets to take her medicines. She thought that the same problem might be faced by other old people. She got an idea from here to start a business, to develop an instrument for old people that could be fitted with an electronic device connected to the mobile phones of members of their family which could indicate the location of old people when they go outside their homes. This device was to be kept in their pockets. She also thought to fit a timer in the instrument that could remind the old persons about the time of taking their medicines. She also made it a point to observe her grandmother sometimes during the morning walk to see the functioning of the device. Sudha also studied pros and cons of production before launching it.

She contacted a professional, Sanjay, as advised by her friend, and asked him to give his valuable technical assistance and capital to finance her ideas.
