Learning from my own mistakes

I wish I would never make a mistake. But, that is not so. So here I am learning from my own mistakes. Though it is tough. Gives me a hard punch in my stomach. But, I have to do it. Have no choice.

To cite an example, I was asked to setup a help desk software for my company to use. I did some analysis and some trial runs. 

First one, was installed on our server but was very rudimentary. When I gave a demo to my manager. He was not too impressed. So I set onto searching more. 

Second one, was installed on cloud. It costed around $10, but we could not customize it cheap. I just informed him that am searching. But, I did tell him the cost and he was like not much.

Third one, again was installed on cloud and as i did some settings figured it was $15. Since I was on trial version I saw a similar flavor of all customization was available at a lower cost. I confirmed with the support agent and he also agreed that I should go for $25 rather than $40.

I told my manager, showed him the demo and he was all happy with it.

However, later today I found that the low cost one did not give the customization I want.  At this juncture, I hate to go back to my manager and tell him the cost. Ouch! my stomach hurts now.

Another example of today, when the team proposed a solution they gave a certain estimate based on assumptions that were never written. When this project got handed down to me for requirements, I was told nothing about those assumptions. All through the requirements things went back and forth, wire frames were designed and still no assumptions came alive. Now, when we started the design discussion some 2 months later that assumption suddenly came afloat and the blame game started. The design team/ estimation team asked me to go back and inform the customer for scope change and to pay more. 

Suddenly, it appears the whole mistake was done my me in my requirements. But, I clearly remember telling these folks that this is how the current system behaves. It appears they did not even hear it.

Not liking the day today. Nothing seems to be going as expected and I have a weird churning in my stomach and a strange shiver.  I don't want to acknowledge or say the STR*** word. I'm not in that area. I know it,

I just need to work and figure I do not make these mistakes again.
