When fix is painful than defect (Medicine pains more than illness)
Get to Theory
A small half cup (like that of cough syrup bottle) will contain 1 KG of water vis-a-vis around 74 mL of water. This is the practical way of informing the density concept to children, instead defining in formal physical terms like ratio of unit mass to unit volume expresses in kg/cu.m etc.
However as the child grows perception of density becomes a concept and understand the definition formally. When the child was not able to visualize concept, a direct visual demo was required as the child could not apply the density with just basic perception. However when the child becomes grown up, it will need to understand and extend the concept to broader areas and will be able to derive the density of various substance on its own use the property of density in the relevant application.
The point am trying to suggest is that quick and hot fixes in the name of Agile, will impair the long term solution/product rather than strengthen it. Here we need the help of theory and concepts. Addressing the root causes and systematically eliminating them will make the model more solid and ensure that product / service is evolving in consistent and effective manner. There are cases where the fix is taking so much effort and cost than the leaving the actual defect in the system, resulting in more CoPQ. Looking at this way also predictive capabilities if remain the focus and applied in true manner, then will ensure meeting long term objectives of all customers.
Solid grounding on basic concepts will help, in the words of great Toyota way provide the customers with what they want when they want and in the amount they want.
