below: size – 300 KLOC, Complexity 0.95, Analyst cap ability – 1.05,
Applications of Software Engineering Methods – 0.8, Performance
Requirement – 0.75. Calculate the effort for three types of projects i.e. organic,
semidetached and embedded using COCOMO model.

Q. 3. (a) What is the use of drawing context diagram?

(b) A blood bank receives and stores blood donated by people and also gives
blood to individuals or hospitals on demand. The blood bank also has a panel of
vendors who supply var ious items after receiving the order from the blood
bank. If a dono r appro aches the blood bank, his blood sample is taken and test

regular donor are also informed by post. The blood bank also has a panel of
doctors. Two doctors from the panel are also associated with th e camp to
handle emergencies. For these requirements draw (i) ER diagram (ii) Context diagram.
