I have observed that sometimes an architecture tends to get defined by a committee of all stakeholders (or representatives for them) rather than an architecture team. This in itself may not be bad but there are some things that seems to happen when this is the case:
First the architecture tends to be defined by a set of separate decisions that solves separate problems the stakeholders have. There is no overall vision of what the architecture should be. A lack of what Frederick P. Brooks call conceptual integrity.
Second the balancing of quality attributes seem to be an average of everything. The architecture is not really good on anything (maintainability comes to mind). On the other hand no quality attribute seems to be totally forgotten or neglected.
Third the description of the architecture is done at low level, e.g. a design or implementation level because this is what a majority of stakeholders are used to in doing their usual work.

Experiencing To Troubleshoot the Defective Fuel Pump
It sucks when the fuel pump have defect. Because your engine will have empty after how many seconds in travel. I experience this when we are traveling from our City to the Province of Cebu. After we enjoying our travel. In the Middle of Enjoying. The engine suddenly stops. What the heck. Where all shock because we don't know yet how to diagnose for troubleshooting. After we rest for an hour. And starting engine again. The engine Start. its amazing. But after a kilometer travel. Suddenly stops again. Were continuous accelerating but still empty. Until we come in our destination. After we consult in the technician. We found out that our fuel pump are defective. Need to replace.
Overhauling 3 Cylinder Engine
I was on overhauling 3 cylinders engine. First i am disassembling the Engine assembly, and then i was going to remove the oil pan. Then removing the oil strainer for the cause not to be tampered when removing another parts. Then i removed the crankshaft pulley (because there was no timing belt already). Because we buy that in aftermarket. But it still in good condition. After i remove the camshaft pulley because we are replacing the cam lobe because it was have to bad condition. It will not in standard measurement or out of his slide parts because of rust.Important of the parts or bolts to systematize. So that after you will perform overhauling. It will easily put back from where they are. After that we replace the camlobe into the head cylinder. But the stock camlobe are not long as we replace from the aftermarket engine. We replace that for the reason it will have a longer lobe than the stock. So that the distributor assembly can put after it.

My experienced while im studying
Most of the technicians don't have knowledge about automobile wiring. I studied Automotive Services National Competency II. And this only for 5 months and every topics are very important. I was willing to know about how to repair some parts of the engine. And now i know how to overhaul engines, how to grind the valves, and how to know if the the pistons are not good. Thanks to god i know all this.:)
