Lisa Green, a recently appointed and rather shy systems analyst with your systems group, has come to you with an idea that she assures you will save the team time - and hence the business you are consulting with will save money. Lisa proposes that, rather than doing time-consuming interviews or collecting current quantitative and qualitative documents, the team should rely primarily on what it discovers in an archival database. "They have kept everything. They even have their old reports from earlier systems projects. We don't have to talk with anyone; we can access the database all day, without seeing a soul."

a) List the merits of what Lisa is proposing.

b) List the problems with what Lisa is proposing.

c) In a paragraph, explain tactfully to Lisa why the systems team uses many different approaches for gathering data.

Note: Give me specific detail as well as references pls if have
