What is the difference between Agile and Waterfall anyway?

Could you tell us what the difference between Agile and Waterfall?

Sure, Agile guys are super laid back, and waterfall folks are really uptight :)

No, that's not true, I know lot's of uptight agile guys too!There are many differences between Agile methods (XP, SCRUM, Crystal, etc) and traditional "waterfall" methods, and a whole book could (and should) be written about it, but there are a few things that stand out for me (these are not all inclusive by the way).

- In an Agile environment, budget and time are fixed around Releases and Iterations, and scope (within each Release) is negotiable.

- In a waterfall environment, scope is fixed and both budget and schedule are negotiable (no one wants to negotiate these, but they do).

- In an Agile environment, a complete lifecycle is executed incrementally and iteratively against a subset of requirements during each iteration, enabling both the business customer and the development staff to learn along the way. These small sets are delivered to customer in useable chunks.

- In a waterfall environment, the requirements are fixed at the beginning, extensive planning is done, and all changes are managed through a formal change control process. The entire set of requirements is completed, the code is designed, built, and tested, and then delivered.Finally . . .

- In an Agile environment, they pride themselves on focusing more on development and less on documentation (for better or worse)

- In a waterfall environment, most everything is written down, many times (for better or worse)Both of the last items are problematic, but that seems to be the behavior.

Internet Connection from BSNL Gaziabad Exchange

These days i am pretty much busy with setting up basic necessities like Telephone & Gas connection etc. Regarding Telepone, I have taken help from one of my colleague links to get the phone connected. Now i was trying to get internet connection over it. For that i have filled the form 4 times online. (YES! BSNL provides this online facilities to fill the form) But nobody care to even look at it. My maternal brother who is in BSNL Jhalandhar, told me that there is on one who knows how to read information regarding those filled forms hence they don;t care.

So i have submitted the form in person to Ghaziabad exchange at RajNagar. I have been given a number for further enquery regarding my connection. I have dialed the number today when i found that i have received few calls on my home phone during day when i reached to home in evening. After various trials i got the chance to get connected through that number. I was trying to explain my situation to him but it seems he was not interested to listen, on explaining to him, he was trying to tell me we can;t provide information in this way.

I got agitated and asked him to which way he will be able to provide information. But more interesting point was, he was suggesting me to go for AIR TEL and other companies who provide Internet. I was surprised to know that person sitting in BSNL is actually working as AIR TEL agent. I just explain him that let me know the status about my connection as i have all the necessary equipment with me, you just need to come home on Saturday to my house and get it fixed. I don;t know whether that ill-minded person actually got me or not. But i am sure that now i need to talk to my father regarding that as he is in BSNL Kanpur.

I think whatever our PM say, the only way work here is through reference. Professionalism is still faraway from government departments. :)

At ABN AMRO - Level 2 Support really works!

Finally I send my complain to level-2 support at ABN Amro Bank i.e @ 'in.quality.assurance@in.abnamro.com' on Saturday itself. Today on checking my account details online, i found that penalty charges has been reversed and amount has been credited in my account.

I had actually loosen the hope that it might work at level-2 also. But it seems that there are few who really listens even the e-mails of customer too. I like this very much. I think i can recommend this bank for few of my other friends too. :)

ABN AMRO BANK Applying Penalty on Customer Account due to their Own Mistakes

I have deposited a Cheque in the account for clearance on 17th April in NOIDA Branch. At 20th when I view the account statement online, I came to know that Rs 112.24/- have been deducted due to returning of Cheque for REASON OF POST DATED.

After doing bank by phone, I came to know through the Customer Care Staff that banking staff does not really check the date of check weather it is postdated or not.

My question here is, If bank is not doing this checking service for us, then why applying penalty charges on my account? As this error can be stopped at the Bank level itself by ensure proper verification by staff member itself.

Taking over the vehicle on delhi roads

I am driving my car since last six months, and sometime i really find little bit difficult to take over other vehicles especially Big one, like trucks, long trucks, buses etc. It does not mean that i feared to take over them but that made me nervous at that time.

The reason for this nervousness is, as i guess i think too much before crossing over any big vehicle, i see the angel, speed and space (before & after) around that vehicle i need to take over. During this whole calculation i also try not to apply break or change gear. As when i found all those things in my calculated parameter, then i normally go for crossover that vehicle.

All those big does not disturb me that much like motorbikes, as rider has lot of freedom to take any direction, hence i also need to keep in mind that too, and for that i observe his pattern of moving on the road, if he is coming towards my vehicle, i usually do not try to take over and wait till he move to other direction to keep our self safe and secure from any possible accident.

Slipping things from mind if not revised or touched

Today we encounter an error during implementation of a very small thing in current project. It took a little more time to identify the actual place of error. The reason was taking more time, as it is just being adopted from other places where it was executing fine. And we also have verified for copy-paste error :)

So after digging a lot in the complete process finally silly error place has been identified. Then i realized that as we have not worked on that functionality long time. We forgot to keep in mind the simple process of avoiding the error. More on that, we have worked on many more things in between that we almost slipped lot of many old process in this duration.

Now i am realizing why revision is important so much. :)

Calculate Account Balance

Have you ever noticed that calculating account balance might be so tedious tasks?

Few weeks back i have asked in finance dept of my company to calculate the balance for my account. Actually i noticed few months back that there is some mismatch happened with my monthly salary, hence i raised this request to that guy. Day before yesterday he was taking it in quite easy manner. But today when we need to talk on that, i can easily see the frustration and tension on his face. The reason for this was, My salary component has been changed thrice in this whole year, but account guy had not realised this earlier. :)

Now he is working on my account and asking for few minutes :) . Anyway i have no other option than to give him that many minutes he want.
