• This paper provides answers to the following questions -
• Discuss the following questions:
• Boehm says that “In practice, quantifying estimates of P(L) and S(L) is difficult.”. Why do you think this is so?
• References:

• provide answers to the following questions:
• d. What are Lehman’s Laws? Do you agree with Lehman’s third law? Contrast Lehman’s fourth
• law with Brooks’ Law (You will need to read more widely than the set paper to answer this last
• point).

• answer the following questions:
• Can you find out where the title comes from (Against Method-ism)? How is the source of the
• title connected to the views expressed in the paper?

• Discuss the following questions:
• How has the state of component-based reuse changed since 1995?
• How do pipes and filters prevent architectural mismatch?
• Explain how virtualisation prevents architectural mismatch
• What is the four steps build process used by CPAN modules? Comment on the
• viability of such a process with respect to component-based software engineering.
• What type of automated support might be able to detect architectural mismatch?
• How do you think cloud-based services may or may not contribute to what Garlan
• et al. (2009) call “architecture lock-in”? Consider the different layers of cloud
• services (SaaS, PaaS and IaaS) in your answer.

• answer the following questions:
• a. What is Design Science? Does this paper use Design Science as its research method?
• Discuss.
• b. The authors consider the Waterfall Model to be one of a set of “fundamental methodologies”
• [their phrase]. They cite Ramsin and Paige (2008). What do Ramsin and Paige consider to be
• seminal method[ologie]s? Discuss whether the authors claim about the Waterfall Model is
• valid.
• c. What are the five values of Extreme Programming (XP)? Select two other methods and see
• how the values of XP map to those methods. What can you conclude about the values?
• d. Find evidence that firms mix and match parts of methods.
