The cost of fixing a fault for a software product during the implementation phase is approximated at $44,000 USD. How much would the same fault cost had it been identified and corrected during the design phase (approximate $ amount)? Explain and show your work for estimating the cost. 3. If the same fault described in Question 3 (see above) had already been delivered, how much would it cost to identify and correct (approximate $ amount)? Explain and show your work for estimating the cost. 4. You are given the task of estimating the cost of a software product. The cost of development is estimated at $175,000 USD. How much additional cost should be estimated for post-delivery maintenance (approximate $ amount)? Explain and show your work for estimating the cost. 5
