DESIGN OBJECTIVES:

1.The device must be of good quality?

2.The device must be affordable?

3.The device should work automatically?

4.The device should include good storage facility?

1.1 Identify Clients Objectives:-

| Sl.No |     Objectives     |

|   1   |     Reliable       |

|   2   |   Cost Efficient   |

|   3   |     Storage        |

1.2 Prioritize the design objectives:-

| Goals  |  Reliable  |  Storage  | Cost Efficient |  Score  |

|Reliable|   ****     |    1      |       0        |    1    |

|Storage |     1      |   ****    |       1        |    2    |

|Cost Ef |     0      |     1     |      ****      |    1    |
