effectiveness & efficiency and the use of them

1. Discuss the difference between effectiveness & efficiency with suitable examples.

In management terms, efficiency is "doing things right" and effectiveness is doing the right things"

Effectiveness relates the input or the output to the final objectives to be achieved (the outcome)

• efficiency=quality/Input quantity
• Effectiveness=objectives/Input Quantity

In management, effectiveness relates to getting the right things done. Peter Drucker reminds us that effectiveness is an important discipline which “can be learned and must be earned.”

The effectiveness is more difficult to assess than efficiency, since the outcome is influenced political choice. The effectiveness shows the success of the resources used in achieving the objectives set.

Example:
When deploying a transport service, efficiency and effectiveness both comes together to complete the task successfully. In this scenario, effectiveness could be identified by "buying/hiring" vehicles. It means the management should understand the use of the vehicles before buy/hire them. If the management buy wrong type of vehicles to use them for transport service, will lead to bankrupt because some vehicles will not meet the requirements well and will not provide the service which has expected. Some vehicles will not enough for passengers and will make to hire more vehicles. Then it will lead to increase the staff and will make more expenses (vehicle expenses/ salaries to the staff)
Then shall we talk about the efficiency. If the transport service provide the services at unneeded times that less number of passengers using the service, the service will not make profits. So, using a timetable is a must when thinking about the efficiency. It means "doing things right".

2. Which is more important for performance? and Can managers improve both simultaneously?

Efficiency and effectiveness both comes together because both of them are connected to each other. We can't think about the effectiveness without efficiency and we can't think about the efficiency without effectiveness.

Efficiency alone will put the company on the fast track to bankrupt .

Effectiveness (efficacy) alone *may * allow the company to survive. How ever the company will not reach it's maximum potential if it is inefficient.

• Low Efficiency / High Effectiveness
• there is a right goal, but less/poor usage of resources. (leads to expansive result)

• High Efficiency / Low Effectiveness
• Inappropriate goals but right usage of resources. (leads to deliver unwanted products at lower price)

• Low Efficiency / Low Effectiveness
• Works on a wrong target and less/poor usage of resources. (leads to deliver expensive, unwanted products)

• High Efficiency /High Effectiveness
• Works on a Right goal using right resources in a right way. (delivers good/useful products at affordable price)

So, effectiveness & efficiency relates to each other by connecting inputs, outputs and outcomes.

The future computer in 10 years of time

Here is a article which I have written for a discussion forum of our BIT website.

Question:
 
Imagine that you need to order a computer in 10 years time for your personal use. What type of a computer would you expect to have by then. If you see it different from the current PCs, just indicate why you foresee such a change.


Answer:


I think the computers in 10 years of time will be very different than now. People will think about the protection of their data and availability of data. So, people will prefer to use “on line storage” than storing the files on a Hard disk drive. So, no need to use hard disks with high memory capacity. So, manufacturers will make computers without a hard disk. Most of the time, computer will be having only a “web browser” and all the softwares will be installed in the Internet. (currently google tries to do so and “Chrome-OS” will be play more role on it) Then no need to pay for the operating system and softwares because a flat rate of subscription will provide every software needs. What it means is the Internet will be essential to day to day life. So, ever computer will be having inbuilt “High speed data devices” to access to the Internet.

As a result of people live in a very busy, and communication world, people will use “Laptop” computers than now. It will help them to live their mobile life very easily. Manufacturers will make more powerful laptop computers with low weight to easily carry everywhere. “Nuclear cell” batteries will be provide more accurate electricity/current for a long time.

Now, it's not a fiction a computer without a keyboard because Apple Inc has announced a model of a computer without a keyboard. User could type using an “on-screen keyboard” from the movement of his/her eyes. Then no need to type by hand. Then the computer will only be a Screen. By 10 years time, the computer monitor will be a thin paper which could keep inside the pocket.

Artificial intelligence is the main idea of the 5th generation computers. By 10 years of time people will be able to use computer by Voice. Then no need to type anymore and people who blind could use a computer without any difficulties. People could spend their time by talking with the computer when they are lonely. Computer will be provide advices to the user when needed.
