ketika anak kuliahan mencoba memahami pertanyaan penting tentang Business Intelligence

Taken from here.

1. What happened and what is the cause?  
Find technology solutions that provide ways to identify the root cause of issues. This may include filtering or drilling into the drivers behind a specific outcome.

2. What led up to this?
By viewing statistical trend lines, you can determine whether a specific issue happened over time or abruptly. Only with trending information will you be able to accurately assess a problem.

3. If I do nothing what is likely to happen? 
Use trend lines with forecast projections to show future outcomes.

4. Is this a systemic problem or an abnormality? 
Use control charts to show how much change there is from one result to the next – for example, in quality or even sales cycle time – to see if you have a consistent process.  A lot of variance indicates a systemic issue.

5. What happened the same time last year, last quarter, last month? 
Look at the differences in the results achieved the same time last year, last quarter, last month, etc., to see if you are tracking similarly or if there is a difference indicating some change in seasonality or the process itself.

6. How does this compare to a benchmark or best practice? 
Review the difference between results being achieved in one part of your business to another, perhaps a best practice within your organization. You can also use external benchmarks to determine areas requiring improvement.

7. What are the contributors to my issue?
Here, Pareto charts can show you the percentage contribution of each result (great for applying the 80/20 rule.) Or, histograms can show the major “buckets” such as Accounts Receivable aging.

8. What would happen if I made this change? 
The beauty of truly interactive dashboards means that you can now do real-time scenario analysis that shows the result of one or more changes.

Beautiful. I think the business intelligence will more fascinate me in the near future..

ketika anak kulihan bosan melihat tampilan urutan form yang sama..

#Update!
I found out that the competition is for US only. I didnt read properly. But who care? I just dont agree with them because they allow me to choose the country. Or do you think they asked my hometown? Im still confuse. Hehe.

Below is the screenshot of the form that i want to fill-up this morning. Something silly happened. I just cant understand why people always put "country" below the "state". Then for today case, the state didnt change after i select Malaysia as the country. It still show US. Oh god..am i not eligible for the notebook?

Please Google, im one of you biggest fan (read: not cheerleader). I do critics but thats the way i show my love! :p

can you understand?

ketika anak kuliahan mempunyai opini tentang interface facebook yang baru..

The original interface

After i make a bit of space for the profile pic

What do you think?

ketika anak kuliahan bingung dengan error yang terjadi di google's search tool..

Ok, im pretty surprise about the finding. Google's search tool for custom range not working for certain date. My example shows that Google normal site cant search for result starting from October 10th, 2010 until December 6th.

I think this is weird, because Google secure site perfectly show the result starting October 10th, 2010 until December 6th.

Later on, i found that the error happen in patter. For example month is m, day is d and constraint is c. The error happen if you search the day that equal to constraints, but nothing happen if it more than constraint. What is the rule for the constraints?

c < m
if d = c
  swap m, d
  show the result
else
 show the right result
end

Do you see the pattern? I just cant understand why the swap happen. :(
To proof my silly finding, let me show the screenshot of the example. I did it few minutes ago. I hope Google can fix this asap.

My guess: they are doing maintenance, because if i type "Google" in chrome browser it will automatically redirect me to the secure google search page not the normal page.

Normal google site, i did nothing

Then i put 10/1/2010 as the date,
it should show result starting from October 10th. 2010

Error happened! :(

This is the google secure search

I was amaze with the calendar, love it!

Perfecto!! :)

Few funny facts,
# i found this by accident when i was looking for girl that i admire :p
# i mention this in twitter, but no respond from Ms. Mayer and Google admin.
# i cant find any report/submit problem menu in those very simple+elegant search page.

Hey google (if you put g instead of G, it will consider misspell), i admire you so much!! Please fix this. Hehe.

ketika anak kuliahan dengerin just a dream-nya nelly..

I was thinkin about her, thinkin about me.

Thinkin about us, what we gonna be?

Open my eyes, yeah; it was only just a dream.

So I travel back, down that road.

When she come back? No one knows.

I realize, yeah, it was only just a dream...

ketika anak kuliahan lelah berpikir tentang database

Saya memilih tidur.
Itu adalah solusi terbaik. Hehe.

Semalem, tiba-tiba ngebuka catatan ide-ide lama. NoSQL..yang artinya non relational database. Kalo search di internet dan baca dari wikipedia, katanya sih lagi ngetrend. Dari sinilah semuanya bermula. Sedikit baca (seriously, it was really hard reading) tentang BigTable, Dynamo dan akhirnya Cassandra dari Apache.

Pusing...

Oh final exam, semoga cepat berakhir....
