I should get more tight fitting metrosexual shirts! There’s still a belly there, but its the type that ladies like… not the excessive one!

27th January 2009, 6 months ago

This is a period where I start to gung ho, gymming 3-5 times a week~!

2nd September 2008

Mmmm… just joined gym. “One day I’ll be like you, Edwin” [dreams] This was during Sheesh’s birthday!

28th May 2008, 1 year ago

Chubby, chubby. Nervous times, cuz previous sem failed “The Financial System” and “Macroeconomics”. This one, barely made it for “Business Marketing”. Very depressed then.

7th October 2007

Very testing times of my life. Turned 21 in a very “challenging” period. It is a miracle I made it through, in one [big] piece.

See the difference??

Thank you, Lukas!

But you’ll be SHOCKED when you see my photos aged 8-16 year-on-year. The shape of graph of my weight would roughly look like the growth number of facebook users over the past 12 months!!!! hahaha…

Badminton later, woo.. time to pwn some noobs. Pool will be in the agenda as always. Its not a matter of whether, but rather how frequently!

E-mail and Snail mail are EFFECTIVE in getting Donations for Charity

Mmmm… I’ll be rich! But yeah, there are limitations… the other alternative was Telephone, and I prove that its not that good if you use Telephone.

One thing that would be totally awesome would be the Internet. I aligned my APM and DMM and IC and NF knowledge to deduce that internet is the way of the future. :”)

Executive Summary

Moonlighters is a Not for Profit organization facilitating a system of giving money, food or help free to those who are in need because they are ill, poor or homeless, to provide money or help in this way. As a charitable organization, they rely on public donations to run their day-to-day activities.

During their recent mail campaign, only 5% of the donor list made a donation. On a database of 20,000 people, the net return was a paltry $10,000.

This report uses Microsoft Excel and some Statistical Analysis through Regression to find out a suitable model to explain and improve the current targeting methods. Out of the 26 variable provided, only 6-8 variables are useful in determining the amount donated. However, other demographical and socio-economical factors can help explain further on the models being used.

In short, we concluded that Mail and Email are the best ways to send promotional materials. Our ROI was between 5-8 times, whereas the potential for Telephone to convert into pledges was a very slim 2 times.

We mustn’t completely ignore the effectiveness of telephone. This is because, with a good telemarketer and an up-to-date contacts list and fact file, many people can be persuaded to contribute or donate.

Whilst the above 2 methods are good, the future lies within the Internet. With varying technologies in place, online marketing is the way of the future. Technologies such as social-networking sites like Facebook and MySpace helps links the wealthy and influential people on cyberspace. A lot of information can be displayed on a corporate website which will make the organization more transparent and relevant.

Another common promotional activity is through Blogs. Web logs or Blogs are websites created by an average Joe who loves telling the world about what has been happening. Various Web 2.0 technologies enable linking and searching of relevant and up to date sites. This introduces viral marketing where when someone learns about something interesting or beneficial, he can easily share it to the world, may it be through e-mail, Twitter, blogs, social-network sites, or social-news site. Once the awareness has been created in the blogosphere, the traditional News networks will pick it up, blowing the whole campaign to into an astronomical scale.

Introduction and Statement of the Management problem

This assignment requires us to find ways to better target our advertising campaign to obtain better returns.

A list of 20,000 records was given. We used a two-pronged attack configuration.

1. Remove all Non Donors (or people who have never donated)
We ended up with only 989 donors.
We then analysed on how best to reach them; either by Phone or Email or Mail

2. Using the same 20,000 records, we found out who can be reached; some by phone, some by e-mail and the rest by mail. We ended up with 11,067 records.

Some assumptions we have to make are:

1. Homephone is the only telecommunication option available to them. There is no mention of handphones, pagers or other methods which are common in today’s world. Therefore, these findings and models are based on Home telephone only, which not many people have nowadays.

On the same note, this could be an advantage because when a person is at home, he is usually relatively free and available to talk. On a handphone, he might be driving or having a class or meeting when the telemarketer calls.

2. Since this project is a Donation for Charity, the amount different people of different demographics gives may vary greatly. Not all donors are rich. Not all rich people are donors.

3. When disclosing information to researchers and marketers, people tend not to be entirely honest. Certain private information might be misconstrued.

4. Data might have changed between the time of capture and when the data is processed. A person might have changed job, changed house, bought a PC / phone, bought more Cars or a senior citizen might have died. To ensure a good model, the list must be current and updated.

Description of Analytical Model

Step 1: Creating dataset containing Current donors

Using the sort function to sort the Donation Column, I deleted all records with the values “0” meaning that this person did not donate to the charity.

Step 2: Variables which are useful indicators

I found that the variables Lifetime, Gifts, Average Gift, Promotions, RecentGifts, Sales, Cars, Technical are significant depending on the model used.

Years since First / Last is not that useful because donator’s behavior changes over time. In different phases of a person’s life, he might have heavier personal commitments like house and car loans, marriage or holiday expenditures. As long as a person has donated before, it is safe to assume they are willing to donate again.

It is harder to get non-donors to donate, and the Returns might not be as good.

The Major Donor Indicator was not used because only 48 records were found. There was no notable pattern observed.

Age is not a factor.

Home Phone / PC Owner / Catalog Shopper – these three variables do not affect whether or not a person donates.

MedHouseInc – Donation is voluntary. Not all donors are rich. Not all rich people are donors.

Occupation based percentages which are significant are included in the results below.

Percentage of Senior Citizens in the community did not affect the Regression results.

Education is also not a factor when targeting for donors.

Results

Basic Information

1. There are 989 Current Donors.

2. Using the CountIf function in excel, here are the results:

10,116 people can be contacted by phone
2,227 people can be reached by e-mail
1,276 of the above can be contacted by BOTH phone and e-mail

Of the 989 Current donors:

Total 989
Phone 476
Email 113
Phone & Email 58

No phone/email 458

Step 2: About the Model

As a general guide to whether or not a value is Significant, the t Stat must be greater than modulus / absolute 2. The P-value must be less than 0.05

Step 3: The models

Total Current Donor

Donations (Y) = 18.403 + 0.059 (Lifetime) – 0.542 (Gifts) + 1.317 (AvgGifts) – 2.935 (RecentGifts) + 29.483 (Sales)

By Phone

Donation (Y) = 3.998 + 2.407 (AvgGift) – 1.325 (RecentGifts) – 46.954 (Technical) + 32.577 (Sales)

By E-mail

Donation (Y) = 13.881 + 0.085 (Lifetime) + 1.201 (AvgGift) – 0.265 (Promotions) – 3.922 (RecentGifts) + 62.225 (Sales) + 33.913 (Cars)

3. Conclusion / Recommendation

When doing regression analysis, we should be careful to never assume and generalise who will donate and who would not donate. Donation is a form of free will and although the data shows that donation is wholly contributed by specific groups, we can never be too sure to assume the other specific groups will not donate later on in the future.

The reason for them not donating could be probably because it is not the right timing at the time of survey.

Therefore with this theory we should still include the other specific groups but minimize the campaign cost on these “less-value” targeted groups. As for the specific groups that have been successfully donating, we should focus more on them by focusing our attention more to them.

Pros & Cons of 3 alternative campaign strategies:

Strategy 1: Mail

After filtering the Current Donors, we are left with 989 records. These people are the ones we intend to send mail to. The total cost is $2890.

The estimated donations received using the model is $27099 which garners a profit of $24209

Strategy 2: Telephone

There are 476 people from current donors who are contactable by Telephone.

Putting in the numbers into the model developed for Telephone, we get $6324 estimated donation giving $4325 profit.

Strategy 3: E-mail

Very few people have access to a Home computer. There were 113 records found. The donations estimated is $10414 with a profit of $8858

Below is a table with further information

TOTAL COST ESTIMATED DONATIONS Profits ROI (X)
Strategy A Mail
Fixed Cost 2000
Individual cost 0.9
Count 989 2890 27099 24209 8.4

Strategy B Telephone
Fixed Cost 1500
Individual Cost 1
Count 476 2000 6324 4325 2.2

Strategy C Email
Fixed Cost 1500
Email 1
Count 113 1557 10414 8858 5.7

From the previous table, we can deduce several interesting findings:

1. Traditional Mail is still the most effective way to encourage donation, closely followed by E-mail.

This is so because a lot of information can be delivered through these two media.

A potential donor can take his time to read the material in his leisure time and make a decision whether or not to donate. There is nobody rushing him, and he would psychologically feel more generous to have the proposal in front of him before committing an amount of money to the charity.

With modern software, email and letters can be personalized with salutations.

2. Telephone is not so successful because it is not the right way to sell or market to a client / donor. The target might be busy driving, cooking, chatting with friends, busy with work or having a bathe. If they are not reachable, they are unlikely to call back. Even if they do, the response would not be that good.

In general, tele-marketers have a bad name. They are usually associated with credit card scams, fake lottery winnings and pyramid schemes as well as unsolicited spamming or request for information via surveys. People usually hate it when they receive phone calls from marketers.

A grand total of 11,067 people can be contacted either by Home Phone or E-mail.

1,587 people have been accounted for in my models.

Therefore, a total of 9480 have yet to be reached or has not made a donation.

Recommendations

A. Who to TARGET?

We have identified 9,480 people being potential targets because they have not yet donated to the charity. There is no way to categorise this group of people because we do not know how much they are willing to donate.

As said earlier, not all donors are rich. Not all rich people are donors.

B. How to campaign (which methods)?

Based on my findings, the campaign to use is Postal Mail and E-mail.

Week 1 – Send out postal mail
Week 3 – Send out phone / e-mail reminders to remind the people whose records are available

C. Various alternative mixes to get the maximum donations.

The most important asset of this charity is the amount of existing donors (or people who have donated before). This is the most valuable group because they are known to be quite generous.

Given a budget, we should allocate about 60% of available funds to entice them (the 1,587 people) to give more donation.

The balance of 40% should be targeted to the 9,480 people who are potential targets but have not yet made a donation.

Another thing to look out for is % sales in the neighbourhood. This group of people have consistently been giving generously.

4. Technical Appendices – Methods

1. Make copies of the Original Data for manipulation.

2. Clean the list using the sort function
a. Make copies of the cleaned data

3. Use the sort function again to find HomePhone = 1 and PCOwner = 1
a. Make copies of the cleaned data

4. To build a model, select Donation as (Y) and up to 16 variables at one time.

5. There are some variables which are not able to be compute, like Age. In this case, we merely remove them from our model.

6. Using t Stat > |2| and P-value < 0.05, Anova value F > 5 and significance F < 0.05 , we can evaluate whether how good the model is.

7. R square is the percentage change of Y (in this case Donation) for a unit change of X (in this case, the 6-8 different variables chosen to be Significant)

8. To calculate Estimated Donations (assuming 100% response), we just apply the X value being the Count. For example, there are 989 people who can be contacted by e-mail, so we replace X with 989 in our model.

9. Residual Plot in a regression offers a good example of what a problem-free plot should look like. There is no odd fan or curved trends in the plot, the average of the residuals is zero, and the points are equally represented about the x-axis. This residual represents the difference between the observed response variable Y and the value predicted by the regression line.

10. Line of best fit (trend line) - A line on a scatter plot which can be drawn near the points to more clearly show the trend between two sets of data.

The line of best that rises quickly from left to right is called a positive correlation.
The line of best that falls down quickly from left to the right is called a negative correlation
Strong positive and negative correlations have data points very close to the line of best fit..
Weak positive and negative correlations have data points that are not clustered near or on the line of best fit.
Data points that are not close to the line of best fit are called outliers.

Formulae

1. Use
Data | Sort | Sort By
Then Select the Field to sort by.
It doesn’t matter ascending or descending, so as long as the Zeros are separated from the Ones. We then delete the appropriate values and records accordingly.

2. Using Cell-Referencing to ensure completeness and accuracy of data

='Current Donor FINAL'!B17+'Current Donor FINAL'!B18*Master!C13+'Current Donor FINAL'!B19*Master!C13+'Current Donor FINAL'!B20*Master!C13+'Current Donor FINAL'!B21*Master!C13+'Current Donor FINAL'!B22*Master!C13

In this example, the regression output on “Current Donor FINAL” sheet is used in the Master sheet pointing to the Count (number of donors). The predicted output is extremely accurate but for analytical purposes, we round it to 3 decimal places.

=ABS('Phone REGRESSION FINAL'!B17+'Phone REGRESSION FINAL'!B18*Master!C18+'Phone REGRESSION FINAL'!B19*Master!C18+'Phone REGRESSION FINAL'!B20*Master!C18+'Phone REGRESSION FINAL'!B21*Master!C18)

Sometimes in regression, a negative value may be obtained. In this case, the Absolute or Modulus function is used

Residual Plots

If the residual plot is random (and the conditions t Stat > |2| and P-value < 0.05, Anova value F > 5 and significance F < 0.05 are met), this variable is significant

Line Fit Plot

Note that there are many “outliers” where the blue dots do not align with the pink dots.

Due to the uncertain nature of donations being unpredictable, the R-Square for all models described in this assignment is between 50-55%. This means that based on a demographic or characteristic profile of a donor, there is a coin-flip chance that he will donate to our charity and proving that my model is correct.

Here’s a graphic on what I mean by the above.

Take some time to digest the above information. Ready?

I guess it is pretty self explanatory. However, the proportion of people for different cases and scenarios might not be the same. There are close to 2 billion people born poor; right off the bat. Only 1,000,000 are born to Royalty, Prime Ministers and prominent figures.

My model might be incomplete. If you got suggestions, I’m really open to it.

But my theory remains that, hey, we are just the same.

[edited 22/04/2009 with more Information]

During my meeting with Adeline Chong, we learnt from one another a lot of things. Among the things discussed was life, business, friendships, and the one that I’m excited about, failure (phailure, phailed, phail, you get the idea).

Abit about Adeline. During her Primary 6 exam (the trials), all students were mixed up sorted alphabetically across the 4 classes in our school (Red, Green, Blue, Yellow). Due to some administrative cock up, they (actually Mr. Tiwary, the Senior Assistant) decided to put Adeline in an all boys class. I’m guessing it was the 2nd class lah (in order), so I was there cuz my name is Philip (P) and she was at the last spot since its Adeline (A). <- ok, that was being TOO specific unnecessarily. Or unnecessarily too specific!

Adeline Wept.

Upon reflection, back then it wasn’t kewl to mix with guys. Don’t know why lah, but she didn’t feel comfortable having all that attention, I guess.

The Future Queen of Brunei, now Princess Sarah [wiki: Pengiran Anak Sarah | Crown Prince of Brunei] was her classmate (thus my schoolmate). My portfolio of friends from Brunei include, a lawyer, family doctor for the royal family, someone to take care of the nutritional needs of the country as well as to control epidemics, the ministers of foreign affairs and minister of defence (tactical), we’ve got a soldier (possibly an army general), more backup doctors and dentists, a couple of engineers (mechanical and the construction type), people in IT and Telecommunications, a professional vocalist, we’ve got all our bases covered. I find myself as the advisor to the Minister of Finance (also the Sultan) on how to manage people and money.

If Brunei were to start a war with Sarawak (oil or territorial issues), we got the backend support to get it done. OK, 25% of those mentioned are Malaysians lah, but still, product of the BEST school of that time, St. Andrew’s School.

It surprises me to see some contrasting fortunes for different personality types. I for one, was quite “promising” (hehe, self praise). I was top 10 throughout Primary School and within the top half in Secondary School. 2005 I flunked Engineering Diploma, 2006 my TER for an Aussie Matriculation was a pathetic 70+ where most friends get 85 and above, mostly in the 95 and above range. I flunked Finance (twice) and skipped a semester (thats about RM 11,000 + RM 5500). Hospital bills due to this failure (long story), also 5-figures.

A playful boy (that we all know and love back in high school) ends up being a decently successful engineer. A good looking guy (said by many) became a pilot flying in Newcastle Upon Tyne somewhere in London. We’ve got lots of Aussie graduates from Monash, Perth and of course, the overhyped, overpriced Melbourne U. My IT partner for all the school IT projects didn’t persue this useless course (of IT) but went for something so canggih it blows my mind away. He’ll be the future tactician for the Brunei army.

God works in mysterious ways.

The failures. So far only a handful have shared their so-called “failures” with me. I wouldn’t call it a failure because it is just a stepping stone to success. Sounds cliche (Gail – for you Arsenal fans) but I really believe its true. God has a greater plan in store for you.

I’m speaking for myself here when I say that “everyone has a rough patch in their life, especially during tertiary education”. All the mixed emotions, hormonal and biological changes (sic boobs, man boobs included) as well as our surroundings.

According to the 5-minute presentation entitled “Do You Know”, back in 1900, they say a week’s worth of New York Times is more information that any living human being will encounter throughout his lifespan. They predict in 2009, about 4,000,000 Terabytes of unique information will be produced. Ok, so the number is skewed due to the huge Science and research databases, and all those Sarah Palin porn. But isn’t it amazing?

Everyone deserves a second chance. Being a high flier in Kindergarden and Primary School does not guarantee future success. I feel I’m lucky considering that I hit my peak in the critical stages of my life. Its like going 3-0 down on halftime to win it on penalties in the end. That’s how I feel my life is. Its all about finishing strong in life.

Aim high. Don’t settle for mediocrisy. It may sound way off but my financial goals in life is to earn 5-figures off the bat, millionaire in 24 months and billionaire in 8 years. I won’t settle for a 12 hour 6 day week stressful job paying rm 6 an hour plus benefits (once u break it down) and having to put up with shitty bosses. Heck no.

I feel that in life, we are limited by the limits we were implanted with by the rich and successful. If everyone’s a boss, who will be the employees? Who will be the garbage collectors and waiter / waitresses of the society? Who will fix our Astro, and clean up our sewerage and be our doorman and drivers and amahs?

We were born naked and equal. So too will we die naked and equal.

Life is like a game of dice. 6 possibilities, everybody on earth has an equal chance. Breaking down the math, yes, there are various variables and environmental factors. Whatever your roll was, there are about a billion people just like you. Its what you do with your life and the ways you impacted this world that will be remembered by history.

Bottom line

1. If you’ve experience a huge failure in life, pick your self up. Give yourself time and never ever give up.

2. If you’re still high flying, and everything is rosey for you, thank God for it. I believe you will be successful. But prepare yourself for failure. You can never be too prepared for that.

3. Outward appearance does not truly reflect how a person is currently feeling; the problems he is facing. In the words of The Killers – “Are we human, or are we dancers?”

4. Remove negative feelings. Go jogging, dancing or gymming. And don’t forget to reward yourself with Haagen Daaz or Carl’s Jr once a while. Open up to the world and embrace the fallen nature due to our forefathers. No one is perfect. Acknowledge that we have fallen. Acknowledge that we make mistakes. Acknowledge that we are not always right.

5. Never give up. Never lose hope. Encourage, don’t pull people down with your negativity.
