4. Using intermediate COCOMO (semi-detached mode), perform a work estimate for a project with the function point estimates in the table below. Assume the programming language is Ada 1983 using the Reifer model. All development factors are nominal. Attribute Number Complexity External inputs 12 Complex 8 Complex External outputs External inquiries 4 Simple Internal files 7 Average Average 6 External interfaces 5. Compare the cost of the project in Problem 4 with an alternative of modifying an existing software system requiring modification of 30% of the design, 40% of the code, and requiring 50% of the testing of a new product of similar size (approximately the same SLOC as in Problem 4). Assume maintenance costs are the same for both options, so only development costs need to be considered.
