I once commented the entry, What Makes a Good Business Analyst by Rajan Chandras, with an easy tone, If You Can Make it Here, You Can Make it Anywhere. The standards of a good analyst conclude by Rajan, in my opinion, are somewhat of very high bars.

In the recent SASCOM Magazine, Ted Cuzzillo published a relatively moderate enty, say, The Making of An Analyst. This paper is considered the fresh graduates to be an analysts in their first job hunting. Yes, there two posts are more compatible than oppositive. Rajan’s targets are those veteran analysts with years of experience.

If You Can Make it Here, You Can Make it Anywhere: On What Makes a Good Business Analyst by Rajan Chandras

In the latest post, What Makes a Good Business Analyst?, Rajan Chandras cites some soft items from Forrester’s Business Analyst Assessment Workbook:

  • Ability to think abstractly, identify patterns, and generate ideas and solutions
  • Understanding of when and how to escalate issues or needs
  • Understanding of and ability to delivery the appropriate level of detail needed for each task
  • Interest in exploring and understanding new concepts and topic areas
  • Emotionally invested in the work
  • Ability to learn by shadowing stakeholders
  • Ability to clearly articulate technology in terms stakeholders can understand
  • Understanding of the organizational culture and its impact on processes and projects (this one seems obvious, but the latter phrase is more profound than might seem at first glance)
  • Ability to drive a decision analysis and selection process
  • Ability to recognize patterns in requirements and categorize them appropriately

What’s more, there are some suggestions by Rajan Chandras himself:

  • Know the organization’s external environment: its competitive position, current state of the industry, geographical & social factors, etc.
  • Know the organization’s internal environment: its financial position, organization culture, IT maturity, etc.
  • Adapt to the needs (your language, dress etc.), but be yourself. Imperfect, yet genuine, is fine; falsity comes through easily, and will destroy your credibility in no time.

No doubt, no boss can reject such a perfect analyst. But I’m afraid these standards are suitable for every professionals. That is to say, they create a model to explain everything. It is too universal to be served as a good filter to select the most proper analysts. She or he may more marketable in any other business line.

Data Mining in Stock Market? Is it crazy? or is it just a hopeless try? Every mentor in mathematics and finance educates us that the stock market is too chaotic and sentimental to use mathematical models. Most of all gift rock scientists are concentrated in the study of interest of rates and fixed income securities. It sounds profitable to use mathematical and statistical models to predict the price of stock, but there are little successfull stories.

I know I might hold some academic doctrines, so I have interest to monitor any effort to try to forecast stock prices using data mining techniques. Some links from a popular data mining blog , Data Mining Research, are listed as follows:

During the many years I've been looking at customer data with SAS Text Miner, I've run into a few situations where I've wondered if I need danger money and here's why:

I had an interesting experience analysing some consumer security software Web search results of the 'less than savory' kind. Colorful language is common in the younger generation (18 yrs +/- ~6 yrs) Web sites, and colorful Web sites are just plain common. An innocent search can lead you to places you never intended to go. While you are likely to come across this kind of html data for text mining/text analytics at some point (like I did), I am always pleased to see that Text Miner creates its own segment for this data and I can treat it as noise and continue my analysis focusing on analyzing more useful trends.
