How good is your game (theory)?
The game theory is a that first created by John von Neuman and Oskar Morgenstern in the 1940s' but made famous by John Nash (watch "A Beautiful Mind", based on John Nash) in the 1950s' as the basis of creation for the modern field of Game Theory. The theory, through the use of deep mathematics and interactive models, tries to predict outcomes in complex circumstance and situations. Some applications of this theory can be seen in preparing business negotiations, analyzing future market conditions, strategic decision making, and assessing the viability of a new venture, business model, program, project, product, service or technology. But the hang up with the theory is that assumptions need to be made. In other words, a guess with a university education. The assumptions have to be made to simplify the real world because it is too complext for the theory to work propertly and with any type of precision. So if it

1 hat, 2 hat; green hat, blue hat --- Dr. Suess
If you're like me, sometimes its just better to wear a hat than to hassle with your hair in the mornings. And its a pretty easy decision: bad hair and/or lazy = hat day. But when it comes to making a decision there is more than one hat to be worn and actually there is 6 and each has a color. And honestly this is my favorite theory and I try to incorporate this into my own daily decisions. Oh and for those curious http://www.mindtools.com/pages/article/newTED_07.htm
this is the website. But instead of going through each hat, I'll let you read the article and comment on what you think. In the four years attending UMSL, I have lost count the number of projects I'm had been assigned and apart of that a decision had to be made where this theory came into play without anyone realizing it. And for those out you who took 4850 or will know what I'm talking about. But also for anyone that is apart of a company or student organization and in a decision making capacity. This theory, if followed can help those "stuck" in a one hat minded strategy to look past or try a new way of thinking, planning, or strategizing. As having been in a leadership position recently, thinking outside the box or is different degrees is vital to making decisions and keeping the company, organization, or group of people on track. But also to have different people specializing in wearing one hat each can also be helpful as then the leader can wear the blue hat (if you read the article you'll know what I'm talking about) and it then will give an organization/company exec board a number of people bringing their own degree of expertise to make a solution or decision. I look forward to your comments.

May the force (field analysis) be with you
Yea you guessed it, I am a Star Wars fan. And I'd like to talk to you about it some more but we have more important issues pressing like discussing what force field analysis is and how it has no relation to Star Wars.
OK, so force field analysis is used for looking at all the forces for and against a decision, so says
http://www.mindtools.com/pages/article/newTED_06.htm. Basically it helps enforce the forces supporting your decision and reduce the impact of oppositional forces (ie people, time constraints, lack of supplies, etc). So here we go again with another graph and possible conflict in deciding how much each force is worth to you (that seems to be a commonality lately don't you think).
Like many of the same past examples, you have a decision to make and in the example on the website, your deciding to upgrade a factory with spanky new manufacturing equipment. You judge what forces support your decision and give them a score of 1-5 and what forces oppose your decision. Going with the example, one "negative" force is the fear of the staff of the new technology with a score of 3. Now how did the decision maker come to think that score was appropriate? Did he/she take a general survey of the staff or just guess that 3 was a good guess. Also with the purchase of new equipment one has to consider the salvage cost of the equipment after it's life cycle is complete which would impact the cost, hopefully lowering the score some. So when making a large decision that is impacted by different forces with one being the time and efforts of employees and people, how do you go about determining how much of a score is warranted. And remember that when making such a large scale and impacting decision, how will it change the employees' way of life, from simple adjustment due to new tech to if layoffs need to occur. Just a thought.

Pros, Cons, and PMI
I'm still at it folks. And we have coffee up so come and join me. Here's a topic some of us might be familiar with because its been used for awhile.....a few hundred years awhile. What PMI stands for is "Plus/Minus/Interesting". Kinda simple right. Oh and it gets better. Much like a prior theory, you'll be making another table/graph. Go to http://www.mindtools.com/pages/article/newTED_05.htm
if you need help in doing this. This might actually be one, if not, the simplest decision making theory out there. So you want to make a decision you make out this graph and right down each positive, negative, and interesting (PMI) fact of a decision and get each a score. You add up the score and which ever totals out more, thats your decision. Wow and life just got easier, maybe. I know what your thinking, 'Andy, didn't we just do this one a few theories ago?'. Well yea kind of but it is different even though it does still work off the same premise. You just need to now decide how much each positive/negative/interesting point is worth. The model was based on a 1 to 5 scale but you might need to expand it to a 1 to 10 perhaps. So try it at home and get back to me if it works. I know I'm going to try it.

How deep does your Decision Tree (Analysis) go?
Whats going on everybody? So I don't know if anyone else is counting but it 4 weeks left (est. 28 days) till the semester is over and I'm graduated. Don't know about anyone else but I'm excited. Anyways on to this all important blog thing. So the $64,000 question is how deep is your decision tree? For those who have no idea what I'm talking about http://www.mindtools.com/dectree.html
should be about to help you out. The basis of the theory is to help you choose between several different action opportunities. By dong this you can see the risks, rewards, and outcomes of each decision. Sounds pretty cool, uh? Well I'll spare you the article because I'm sure you'll read it but I will pose a issue. If you have several options, and each option has several risks, rewards, and options, you might be at it all day. But it could also make a good topic for a small company meeting when a decision needs to be made. More minds at a problem might find different solutions and options to solving/making a decision. But it could also be used on a personal level I believe. Like buy a car which is what I'm going through right now. Now I can buy a car which will allow me to get to new places, around town, and no longer depend on the MetroLink and public transportation, allowing me to get a job (potentially better paying, hope so) away from the Metro. But on the other hand, not getting a car could save me money but limit my traveling to where I can get on and off a bus or train. I could make a easy decision tree for all this but again I'll spare the reader. So go out and make a decision tree for yourself and see how deep it really goes. Cheers

Grid Analysis
Hi again folks, I'm back again. I got coffee brewing up in the MIS lab so if your still awake and have nothing better to do, come join me. I have nothing better to do than blog. But enough of this shanidegans, lets get into this shall we. According to http://www.mindtools.com/pages/article/newTED_03.htm
Grid analysis can also be know as Decision Matrix, Pugh Matrix or MAUT (Multi-Attribute Utility Theory) if those ring a bell for anyone reading this. What it does is help you decide between several options. So keeping that in mind, lets set up a scenario and play a little game. Come with me to see how deep the rabbit hole really is. Wow I really need sleep. Say you want to go on vacation after you graduate UMSL (finally). You have saved up $1500 for a week stay someplace at you need help deciding where. You have narrowed it down to Las Vegas, Orlando, Hawaii, New York, Las Angeles, or a very nice stay in the St. Louis area (Ozarks included). Well you make up a grid and list the cities on the left and criteria you wish to consider up top, like price, weather, fun, places you want to see, etc. You give each city and criteria a score and weight and then total it up and the city with the highest score is your new vacation spot. I'm sure you all looked at the site and have seen the example grid. But thats about it. Of course each score is up to you and if your still unhappy with your decision, as the article suggests, giving a higher wieght to a criteria will sway your decision. Only this about this that I have a problem with is that if you don't have a definite score/wieght for each criteria, then you might spend more time deciding what each score/weight needs to go where.

Paired Comparison Analysis
Here's another one folks for those of you who are checking blogs at 11:35 pm on a Sunday. So the paired comparison analysis "helps you to work out the importance of a number of options relative to each other." http://www.mindtools.com/pages/article/newTED_02.htm
This can be very useful when objective data is not in great supply. So the best way to use it is in comparison of two things, or as the article put it, "apples with oranges". This is actually ironic because I just quit a job (for reasons I with holding) that we sold one cable/internet product and compared it against another. The firm went through price, capabilities, client support, the whole 9 yards of it. But it can also be used, of course, on a much higher decison making business level. Like when it would be better to invest more into a new advertising campaign, a piece of machinery, or whatever. But the catch is, like I stated earlier, you have no objective data. So when your priorities are a little, let's say, foggy, or are comparable in importance, paired comparison analysis is a way to help you make a decision. But you can be the judge of that.

80/20 Rule AKA Pareto Analysis
OK for those of you that don't know this rule, I'm sure you've heard of it. The premise of it is by doing 20% of work you can generate 80% of the advantage of doing the entire job. Article is at http://www.mindtools.com/pages/article/newTED_01.htm
if your wondering. The article goes on to say that you need to write out a list of changes you would like to see done. If the list is long then, group related changes and score each item depending on the relevancy to the situation and/or problem. Then take on to change that which has the highest score that you assigned because it will give you the biggest benefit when and if you solve it.
Now what I don't get is why it 20/80? Why can't it be like 25/75 or 30/70 or something else? Or even a fraction or decimal? Or maybe it might mean that, hypothetical, if a 10% amount of work was done then 90% of the entire objective perhaps? mmmmm maybe I think.
But it is useful to find out that major problem that you might be facing and if you solve, it will help you out 80% (more or less).

Data Warehouse Appliance Case Study; Evolution or Revolution?
Hello all readers, in Sauter's 3843 class and beyond. First off let me give you the site I found for which this blog will be written about: http://www.beyeresearch.com/executive/4639
The article is results of a study of data warehouse appliances within certain companies and the financial business benefits from using such a application. The writters of the study defined the purpose of a data warehouse appliance as “The enablement of high-performance data warehousing with a total cost of ownership (TCO) that provides a rapid return on investment (ROI) to the business.” But such application are not that new, having first come into exitence back in the late 1980's. But especially in today's business world, find the quickest return on investment is key, hence the use of a data warehouse application. However, the companies sequestered in the study reported that even though the application did help over all, the most money spent was on the aquisition and integration of the source data into the appplication.
The study writters went on to break down four different types of appliances that they had found:
Native data warehouse appliance where the hardware and software is tightly integrated into a single data warehouse solution. The software and hardware are not individually licensed and cannot be separated. Examples of vendors providing native data warehouse appliances include DATAllegro, Netezza, and Teradata.
Software data warehouse appliance where commercial or open source relational DBMS software is designed and/or optimized for data warehouse processing. The software supports hardware solutions purchased from one or more third-party vendors. Examples of vendors or vendors providing software data warehouse appliances include Greenplum and Sybase (Sybase IQ).
Packaged data warehouse appliance where commercial software and hardware is tuned for data warehousing, is packaged and supplied by a single vendor, and is installed and maintained as a single system. Examples of vendors providing packaged data warehouse appliances include HP (NeoView), IBM (Balanced Warehouse), and Sun/Greenplum (Data Warehouse Appliance).
Data management appliance that offloads data intensive operations from a host computer. The offloaded workload may involve operational, specialized analytics, or archival processing. Examples of vendors providing data management appliances include ParAccel and Dataupia.
With the similarity of each type, the study showed that in the business market, choosing the right type of appliance for a particular warehousing project became exhedingly difficult. However the big differenct was the capability to warehousing projects with varied workloads of simple or complex queries as well as concurrent data warehouse updates. Some distinguishing charateristics involved performance and scalibility,hardware and software reliability, flexibility for expansion, support for preferred third-party hardware and software suppliers, workload management features, and data management and utility capabilities.
I believe that as more companies really on DBMS, the need for such application will increase and become common place amoung all companies, domestic and international. And with this applications, the need for the personal and support will need to come with them thus leading to a greater need of deeper education and knowledge of such systems and applications. Put more simply, MIS/IS degrees reciepents won't have a very hard time finding jobs.
Thanks for reading.
