- Re: Paul Eggert's comments.....
-
- Dear Paul,
-
- I'd like to keep this reply short .... but there are several
- misperceptions in your note which merit comment and some
- correction.
-
- First: Re. Barry Boehm's Software Engineering Economics. I don't
- have my copy in this office, so I can't check it again. But Boehm
- is sensitive to issues of organizational context ... and his book
- was an extremely important contribution to helping managers and
- professionals estimate the costs of large scale (aerospace-like)
- software development projects. The center point of the book is a
- quantitative cost-estimation model: COCOMO. Boehm's book does not
- deal with issues of systems analysis -- ie., what systems are
- appropriate to build. He deals with different issues.
-
- ==============================
- Second: You claim: "The only mention of traditional methods in
- Kling's case study was a dismissive remark about how a
- traditional system analyst would probably have made the mistake
- of choosing TeX over WordPerfect. This brief and (in my view)
- incorrect remark hardly constitutes an honest comparison of two
- rival systems."
-
- The case study is described in section 3, with relatively little
- analysis. The analysis of the case which contrasts discrete
- entity and web models runs through much of sections 4.0 and 5.0
- .. two fairly long sections.
-
- (This is a complex article and cannot be readily comprehended by
- on-line scanning).
-
- ================================
- Third: You claim: "Kling's article presents an extensive
- bibliography for web-like models, but for ``traditional'' models,
- instead of citations the article contains only a conveniently
- weak description that has little to do with how system analysis
- is practiced or taught. If you turn to real practitioners, or
- even real textbooks, you'll find a much different picture."
-
- I encourage you to examine the following books about systems
- analysis or the management of information systems in
- organizations:
-
- Functional Analysis of Office Requirements: A Multiperspective
- Approach. G. Schafer. John Wiley 1988.
-
- Professional Systems Development: Experience, Ideas and Action.
- Niels Erik Anderson, et. al. Prentice Hall, 1990.
-
- Managing Information Systems for Profit. Tim Lincoln (ed). John
- Wiley, 1990.
-
- Corporate IS Management: Text and Cases (3rd Ed.) James cash, et.
- al. Irwin, 1992.
-
-
- Management Information Systems: A Contemporary Perspective. (2nd
- Ed) Kenneth C. Laudon and Jane P. Laudon. McMillan, 1991.
-
- Information Systems: A Management Perspective. Addison-Wesley,
- 1992.
- ==========================
- This is a representative selection of generally better books used
- to teach end-user IS implementation in colleges and universities.
- Each of them is sensitive to the role of organizational context,
- in some way, with varying levels of attention. The attention is
- often strategic (ie, link IS and organizational strategy).
-
- A few of these books mention the term "infrastructure" (a key
- element of web models) but discuss it in 1-2 pages of a 300-500
- page exposition. Most don't use that term, but rfeer to specific
- elements of infrastructure, most commonly to training end users.
- None of them examine the issue that an organization's skill
- levels may be a key part of systems analysis: either in placing
- constraints on what kinds of systems would be appropriate to
- design or acquire .... or in making demands for significant
- organizational development re. setting conditions systematically
- shifting the skills and practices of managers, professionals and
- other system users.
-
- ------------------
- Fourth: I agree that my bibliography could include specific
- citations to the gaps that I see in contemporary books such as
- these. I had an extensive set of references to books and articlke
- which rest on discret entity models in "Defining the Boundaries
- ..." I decided to write "Behind the Tremainal" more as an
- exposition of the value of treating infrastructure as a central
- analytical construct than as an elaborate critique of the
- literature.
-
- ==================
- I appreciate your coments ... because they help me better
- understand how various readers interpret the paper.

- Best wishes,
