Online Education and Interaction

Education Video

Education Video

Coursera is cool. Online Education is cool. Content is cool. But do you know what is not? The interaction. It is damn boring to stay focused in 3 hours for a video lecture. Recently, my wife and I tried our best to study Introduction to Finance and Financial Computation Econometric. The interaction environment in the normal classroom is not always interesting, it is even worse in an online course. Maybe we haven’t used all the resources we have or we haven’t tried hard enough. But to make the model more successful, interactions would be the key.

Offline watching has its benefits: people can watch anytime, anywhere and any videos you like. It sounds good until it comes to practice. People get lazy, some of them are watching half the video and have to stop to do something else. When they come back, they lose time to get into focus again. It takes more time and efforts to really focus and learn quickly with offline video.

Obviously, they are still free, I have no complaint about a specific site. What I mean is “Hey, this is my problem and may be others’ problems, hope you guys can fix it”. I think we need to give more benefits for people, as gamification and gaming theory often do, to let them spend a specific of time in their schedule to finish the video, to really focus. Maybe these sites offer some chance to chat with the professor, some small quiz that can be both challenging and rewarding.

In the long term, I really think that solving this problem is the business key and competitive advantage for any company.

Reality is Broken – Why Game Matters (part 1)

Reality Is Broken

Reality Is Broken

This book offers me a novel approach and surprising idea of thinking. I am influenced by my country’s media on how bad the game can affect people and students’ mind and how bad games are. But this book challenges my long-time sticky idea, and it does a good job. It sounds like a gamification book or articles that me can read somewhere on the Internet, but it actually gives me more than those boring theories.

Good theory of gamification
It provides me a good understand, not just the theory of gamification. How game designers think, how they plan and write stories that are attractive, human friendly and feel very personal to you. The game challenges you, the game rewards you, the game praises you and welcomes you, the game gives you chance after chance when you keep failing.

The book author makes a good comparision with the real life. The real life challenges you, no rewards, punishes you for being wrong, makes you feel like shit when you fail and noone ever cares about how you feel.

The book makes me stop here and start thinking and observing people around me more. People are worried too much about their future, their failure and their life. Games give them what people actually dream for. It actually explains to me how people are addicted to game. It is not just people want to be fun and entertain, it is normal that people are seeking for respected, value recognition and a better life.

Understanding about sociology and psychology
The book also gives a deep understanding of how Massively Multiplayer Online Game works, how it can be used to resolve real world problems. It is quite interesting for me when the author analyzes the World of WarCraft to demonstrates how gamers actually collaborate, get to know each other and together do something to achieve the goal.

Many other examples are also useful and interesting: Wikipedia is a big multiplayer online game, where people try to collaborate, edit and create better articles to achieve a big goal together. Or this fun and interesting game: FreeRice (http://freerice.com/), where you try to achieve your goal and also help to heal the world.

The author analyzes many different aspects of a game that help people to try to achieve their goal, stick to their purposes and try again and again until they got the goal. If we know how to design a good game, we can make people work together to reach one really big goal.

Education would be the next wave

This is our research about the electronic education market, as the CMU Assignment

To look at the whole report, you can read it from here:

In short, we are seeing the new trends in technology, business, politics and market landscape is moving to allow better competition and creates better platforms.

In technology, we have better network bandwidth, better cloud computing, better consuming device (ipad/iphone) and better content generation tools like iBook Author.

In business, we have seen recent trends in education, from traditional education, to distant learning with the materials downloaded/sent to you via DVD, and then to e-learning when you can get interactions with teachers in the online place. The e-education would bring it further, to help you with more interactions with the teachers, with other students, and you can study wherever and whenever you like.

Domain + Tech + Design

 

 

 

 

 

 

 

 

We can see the new hype about education, health care or photography. I believe that in this new era of technology startup, it is time that we are innovating in each industry, to transform the industry into a better format. We have technology there, we have social network there, we have better design there, in iOS or Android platform. The technology industry have gone quite far comparing to other industries like education, healthcare, design, news, food, lifestyle.

We have seen innovations in Education with Coursera, Ucademy, Khan Academy… We have seen more innovations is coming in Healthcare with Misfit Wearable…News is already transformed with iPad, iPhone, social network and how we share news together….

I agree with the article:

The only way out of this innovation gridlock is an expansion in founding team diversity. I believe the missing piece from the DNA in the founding teams of transformational companies is now the domain expert, who has deep insight into the industry they are trying to disrupt.

I think we will see more innovations in each industry, rather than just technology improvement like the last few decades with Microsoft, Google, Facebook, Apple and Amazon.

In the meantime, our project team in CMU has spent a significant amount of time to produce a quite good report on the Education Innovation.

Suggested Frameworks for iOS

Here are some suggested frameworks for iOS development, since I have used all of them quite a lot. I think they are good frameworks/libraries that you may need to know. It could save you a good amount of time in researching and reinventing the wheel.

List of Frameworks/Code Snippets for Objective-C:

iPhone Cocoa Http Server:

CocoaHTTPServer is a small, lightweight, embeddable HTTP server for Mac OS X or iOS applications.

Sometimes developers need an embedded HTTP server in their app. Perhaps it’s a server application with remote monitoring. Or perhaps it’s a desktop application using HTTP for the communication backend. Or perhaps it’s an iOS app providing over-the-air access to documents. Whatever your reason, CocoaHTTPServer can get the job done. It provides:

 

Steve Jobs: What I feel about him

Steve Jobs

Steve Jobs

I finished this book quite a time ago, but I didn’t feel to fully understand and let all the information and knowledge penetrates into my mind. There are conflicts, there are debates, there are loves and hates from everybody. It is so easy for people to judge emotionally and I didn’t think that I understand everything to start writing it out.

There are many lessons inside this book, and each single person takes his own belief from the book. I have my own lessons, hope that it is not emotionally biased and spend time thinking through it for a while.

 

 

Autocratic, it is so necessary in the success of the company. People may believe that Steve Jobs was fired due to his wrong approach of management or people favored a salesman too much more than the product guy. I think it was mainly an organization politics problem, Steve Jobs was right but he did not get enough power and networks to back him up. I believe in his autocratic, as much as I believe in Mark Zuckerberg’s autocratic system. Forecasting an uncertain future is too hard to convince everybody to follow the leader. It is wasting both time and efforts. It was a quite shock for me while reading this article. I agree with the Jeff Bezos’s style of management in this article: https://plus.google.com/112678702228711889851/posts/eVeouesvaVX

Steve Jobs is not a genius, sorry for any of his fans. I don’t underestimate his talents and efforts but no success comes overnight. He was in a hard time after leaving Apple, building NeXT and then Pixar Animation Studios. There were up and downs in his life but he chose to stick into his core value and keep moving forward with innovative ideas. He has a great mind to recognize the great ideas, a great mind on how to make a product perfect. People may say that many ideas are not original by him. If they look deeper into the product development process, there are 2 things people must understand: the possession feeling and a great care of details. I love the ways Steve Jobs take an idea as if it is his own, as if it is his baby. That’s how passion and great care for the products are made from. If the product manager doesn’t have the feeling of the product as his own. Steve Jobs took this possession to a great level, and ignores the original owner as a whole.

The last great thing that I learn from Steve Jobs is details matter, a lot. I learnt from my own product development, from writing my own book. Details matter, a lot. People may not care about how great most of your works are, but they quickly recognize your mistakes. It is part of how people’s psychology works, they would assume you need to produce a great product so the great parts are normal. And negative emotion has a bigger impact than positive emotion.

 

How Information Technology changes global supply chain?

The outsourcing trends started with manufacturing in 1990s and then this trend happened to software industry. This trend helped the software industry grow really fast, creates a lot of entrepreneurs that can only have a small fund to invest. Through freelancers and outsourcing websites, small entrepreneurs can cut cost and outsource parts of their projects to China, Vietnam or India to get their work done with almost the same quality.

 

And now, this trend has been back to manufacturing industry, where small companies and entrepreneurs can outsource the works of manufacturing to China. Do you have a good idea? No problem, you outsource to China to produce some amount of the products, as small as hundred or thousand products for a tiny cost. There is no need to have a factory and the inventory. You only need them when you have the customer orders.
This new trend will bring more innovation from anybody within the U.S., as long as you have a good idea.
Easier to access the workers
In the past, to get your idea implemented, you need to have at least hundreds of thousands dollar initially. It is also much more risky when you have to order at least tens of thousands of products so that the factory can start manufacturing your products. Lots of people fail when they do not have enough money to start or they could not sell all of their products.

Now, things have changed. Based on sites like alibaba.com, U.S. entrepreneurs could get access to a pool of talented manufacturers. These manufacturers accept to work on anything, ranging from a small contract of 100$ to 10,000$ and they could deliver your products quickly. This lowers down the barriers of entry for new entrepreneur and creates more chances for people to step in.

Alibaba business-to-business model has been a huge success, with around 500 companies do their business in alibaba.com. The revenue of the company has grown from 48 million USD in 2004 to 183 million USD in 2006 and it still keeps growing up. The platform of Alibaba allows U.S. companies to hire any Chinese manufacturer they need for a tiny cost. An instant translation service will help both of them communicate with each other accurately.

Lowering down the cost
This not just helps the entrepreneurs but also the small and medium enterprises as well. This lowers down the cost as well as the risks for any companies to invest into their new ideas.

Bdier, a graduate student at M.I.T Media Labs, quitted her job to become a new-age manufacturer. She designed a protocol for making electronic components into Lego-like bricks that could be used by anybody. She then gave the protocol design to the Chinese manufacturer to make it for her.

There are more case studies that people can work on their garage has a good design and then send it to a Chinese manufacturer to make the actual product. This could save these entrepreneurs a lot of money and they can finally create what they love.

Easier to sell and do marketing
Due to the nature of the Internet, it is now easy for a good product or idea to spread out. Facebook, Twitter, Gmail and Youtube now help companies to do viral marketing with a very small cost. People observed the success of many small companies that have cool products and do not need to spend much money on marketing.

Google, Alibaba, and then Dropbox has been successful in the same way. They make good products and then give it out for the world to try it. Then people will tell their friends, and the product grows by word-of-mouth.

Does ERP and SCM Actually Save Money?

Enterprise Resource Planning (in short, ERP) is an organization management system that uses software application to corporate different aspects of the organization, automate and utilize the information between different departments of the organization to make it perform better.  These departments include finance, customer support, supply chain management, distribution, accounting, inventory management…
In our supply chain management, we mostly focus on 3 macro processes of the supply chain framework: Customer Relationship (CRM), Internal Supply Chain (ISCM) and Supplier Relationship (SRM). These 3 supply chain frameworks help the organization to manage its customer, its own process in supply chain (inventory, tagging and accounting…) and its supplier relationship. These macro processes run on a basic framework called Transaction Management Foundation, which include basic components for finance, accounting and human resources… Figure 1 depicts how these 4 frameworks work together.

Figure 1: Frameworks for Supply Chain management

Requirements of a good SCM system
In today competitive world, a good ERP and SCM system has to support the organization with high quality information to quickly make good decisions. To achieve this goal, the information and the system must satisfy multiple requirements:

  • Information must be accurate: it is not necessary for information to be 100% correct but the general picture must be represented truly.
  • Information should not be out of date in a specific period: when managers need information the most, they should have the up-to-date information that can help them make decisions.
  • Information should be in the right format that managers can use it to quickly make the decisions. For example, information might need to be aggregated to help managers know the general state of the supply chain system.
  • Information should be shared between involved managers that help them to understand the same picture.
  • The information system should be updated whenever the business requirement changes, that helps the organization to have the correct and necessary information.
  • The system should be easy to use and requires little training for the staff to work with the system.
  • The system should run with few bugs, always available when the staff or managers need them.

These requirements do not look too hard for an organization to have its own SCM system. In practice, 75% of ERP implementations were considered a failure. This gives us a big question about why an organization could not achieve its goal in designing and implementing an ERP system.
Reasons for failures of ERP system

It is hard to measure a real success of an ERP system. The question is if the benefits the new ERP system brings is much higher than the cost and the risk that the organization has to invest in. There are multiple problems, the lack of the communication between business and IT manager, poor planning to deal with hidden cost, the lack of understanding about the risk and complexity of an IT system.

Risk and Complexity

Business managers usually underestimate the risk and the complexity of a SCM system. A current version of a simple ERP system now consists of millions of lines of code. This is too complex for any small team of people to understand the whole system.

Complexity goes along with a big number of bugs. These bugs cause a risk that managers could not see and estimate it clearly. If the system is down for a couple of hours, it is already millions lost for the company. As in Foxmeyer, 1996, the SAP’s SCM deployment did not expect to handle this level of volume of orders. “We ran some simulations but not with the level of data we have in the operating environment”, one company executive said. Foxmeyer tried to solve this problem by sending hundreds of workers to work around the issues but the underlying software kept failing in middle of the process. Totally, this bug costed Foxmeyer tens of millions of dollars.

Hidden Cost

There are many hidden costs in designing and implementing a new ERP system for the organization that managers usually do not plan for. This makes up the total cost for the implementation to be much higher than the benefits gained from the implementation. According to Jarn, M.2002, there are 5 main costs that managers usually overlook:

  • Training Cost: people usually underestimate this cost. It usually takes a while for staff to adapt from the old system to the new system, for the changing of the old process to the new process.
  • Variety forms of data: data in SCM system is usually not in a standard format. The data come from multiple suppliers and the order requests come from multiple retailers and distribution centers. This makes it very difficult for any firm to standardize this data and match same items from different suppliers. The same iPhone case can be given different descriptions, specifications when it comes from different suppliers from different countries.
  • High Consulting Cost: this usually be overlooked by the consultant and the companies. The consultant may not have enough experience to plan for the project and the project may require longer time to finish or more payment to the consultant.
  • Integration and Implementation: Consultants want to test with the real dry-run to see how it affects the system, but usually the firms don’t want people to touch in their valuable data. This makes the integration, implementation and test process much harder than it is planned.
  • Managers fail to keep the project deadline. Because it is too difficult for consultants to give a correct estimation, most of the SCM projects fail to meet their deadline.

Slow to adapt to new business requirement

Although the companies spend millions dollar on the ERP projects, they also complain that it is too difficult to modify these systems to match their new business requirements. The risks and the complexities of the systems prevent developers and consultants to move quickly with any new business changes

Rethink about Transportation Cost

The oil price is increasing everyday, the politics corruption in China gets worse, the labor cost of Chinese increases quickly and the natural disaster happened in Japan and Thailand. Suffering all above problems, now is the good time for company to think about one question: Will Outsourcing still save cost?
Will Outsourcing still save cost?
There are some significant changes to the structure of the world in the last 20 years. Firstly, we look at the new cost of global supply chain management with the changes of oil price, Chinese labor cost and natural disaster cost. The next section will discuss about the cost of losing sales, market share and brand name by delay transportation.
Oil Price

Figure 1 shows us how the oil price has behaved in the last 25 years. The best time for outsourcing was 1993-2003, where the oil price is stable and only around 40-50$. However, in the last few years, we have seen a new average oil price which is around 80$ and at sometime, the highest price is 140$, when the war in Iraq and then Libya happened.

The labor cost in China has increased 3 times since the last 7 years, going from 1500$ to 4500$. This cost has been marked into the cost of good sales for all companies.
Total Landed Cost-Saving
According to McKinsey (2008), the total landed cost for outsourcing to China has changed significantly since 2003 to 2008

These total landed cost has been affected by the increase in annual wage in China, the cost of shipping and energy. Now, company has suffered 16$ lost when outsourcing the midrange server manufacture to China.
The Effects on Sales, Customer Service and Brand
Outsourcing has a problem, you have to ship the components to the assembly line and then ship the completed products back to US to sell it. There is a cost in this delay. Transportation is usually varied and currently, the transportation has become congested that delay is come more usual. This delay leads to various problems:

  • Over stock or out of stock: this could cost the retailers money when they are over stock and have to pay more for inventories. If they are out of stock, the problem can become worse, they can lose the customer and hurt the brand name.
  • The problem of delay manufacturing. If there is a big delay happens to the factory, the workers will have nothing to do for some days and then have to work overtime in other days.
  • The probability of accident and natural disaster: when the disaster happened in Japan and Thailand, the supply chain management is broken and people need to wait for the products to come out.
  • The global gridlock: there is a traffic congestion by train, truck, ship and air recently. This leads to a delay time in transporting the products to the right place. Actually, the company also needs to rethink between cost of air and ship shipping as shown in Table 2.

  • There are some critical products that could not be delayed, especially health care system of the government. If they could not deliver the vaccine or the drug in the appropriate time, people could die. For example, in case of the heath care vaccine distribution program, the manager said:”It was clear that if a nationwide emergency, such as a bird flu epidemic, put pressure on the vaccine supply, the CDC couldn’t respond the way the public would demand”.

Recommendation
With these problems and effects on the business in the long term, this is the time we may need to rethink about the transportation and outsourcing. The real cost is increasing while the hidden cost of brand name and customer experience becomes more important in this competitive world. We need to start thinking about moving the factories out of China and move it back to near the main sales and distribution place. Mexico could be a good place for U.S. market and European Center would be a nice choice for the whole Europe market…

Company’s objective and product design

Disclaimer: This blog post is from my assignment in the Supply Chain Management course. It is copied from here

The long-term strategy of a company will reflect on how product of that company is designed, how people in the company work together to achieve the same goal. This long-term strategy brings the company ahead of other ones, creates innovation inside the company, and makes a huge profit for the company while others still suffer the economic recession.

http://www.onedesk.com/2011/05/product-strategy-tips-for-success/

Cost Cutting Innovation
IKEA
The last year was an economic recession year with unemployment above 9 percent and housing is 73 percent below the 2006 peak. Given the furniture is one of the worst categories of retail sectors, the support from government and Barack Obama in jobs help did not push this furniture sector much. In this difficult time, IKEA finds it easy to cut down the price of its products. In contrast to this move of IKEA, almost all other commodity prices increase.

Based on interviews with IKEA CEO Mikael Ohlsson, the whole company culture focuses to produce cheaper products. They set the target price for the product first, and then, by any means, to achieve that price. By improving the efficiency in product design, factory manufacturing and then distribution and delivery, it can cut a significant amount of cost.

http://noellebullock.posterous.com/?tag=ikea&page=2

However, one of the key factors is via its supply network, when it can try to use the least sustainable materials in this world. This may mean some long-term impact but that is acceptable for IKEA to reach their long-term goal: cut the price.

Tata Nano
Tata Nano has innovated a new “Open Distribution” system. This system operates by a modular design approach. Every product is designed in terms of modules, or components, which can be built and shipped separately to different assemblies around the world. This helps Tata Nano to achieve its goal.

By using this Open Distribution approach, it allows suppliers to compete for better qualities and lower price to bid for supplying. To push this even more, Tata Nano has its own internal suppliers. These suppliers need to compete fairly with the outside suppliers, so the general competition level is increased.

These innovations help these companies to move forward faster, affect all of their product designs as well as the process to manufacture the products and ship them to assemblies.

Environment Safety First

In contrast with the approach to cut the cost by all means, there are companies that focus on making value and meaningful social responsibilities. These companies also gain high returns through social values, which would enable them to follow these values in the long term.

There is a trend in designing, manufacturing and distributing new products with the most sustainable materials. These materials help companies to achieve its environmental goals.

Herman Miller
The goal of Herman Miller is explicitly stated in its website:

We put Herman Miller’s corporate environmental goal quite simply: to become a sustainable business – manufacturing products without reducting the capacity of environment to provide for future generations

That’s clear. It is the goal of all employees and all products of Herman Miller, to create a sustainable business. That is a meaningful value for everybody, so all employees are proud and happy to work at Herman Miller, to create a social value.

An example of this strategy is when they make a decision about choosing between PVP and TUP. PVP is cheaper, easier for suppliers to work on and there are multiple existing suppliers. TUP, though, is more sustainable for environment but is a new thing and few suppliers are able to provide to Herman Miller with low price. They finally choose to implement TUP since the new product, so they do not have to redesign the existing product and they can be proud about this new product.

This environmental safety first also puts them ahead of other competitors. Due to the strict environmental regulation rules of the governments in product manufacturing, their competitors find a hard time to follow what Herman Miller does.

http://www.hermanmiller.com/about-us/things-that-matter-to-us.html

It also helps Herman Miller to get the best employees for their business, which put them in a competitive advantage position comparing to other companies. The Youtube video clearly demonstrates how Herman Miller could make their employees proud of what they are doing.

These examples give us a broad view of how the company’s long-term strategy and objective affects all their business: from product design to decision-making process to the culture of the company. IKEA has chosen the price to be their competitive difference, and then ignore the environmental side of their works. However, Herman Miller focuses on building sustainable products and business. Both long-term strategies put the ahead of their competitors and make a difference in their business.
