What are the problems encountered in traditional approach tosystem development.

Answer and Explanation:

The following problems are encountered  in following traditional methods to system development:

Low or no productivity as a result of connection lack  between customers and engineers during the development process.Another major reason is the high cost of the traditional methods and most of the time the the features developed using these methods may not be the requirement of the customer resulting in wastage of the budget. These methods are difficult to modify  and make changes to them as these are very rigid and if the changes are introduced then also the process is quite costly that will lead to wastage of resources and money.In the development phase, these processes require a lot of approvals from management side thus leading to delays.These methods are all in all inefficient, rigid, not flexible, results in delays, unproductive and lacks transparency.

answer: when the substance contain the two parts (polar and non-polar) like soap.

explanation:

soap is produced from the basic hydrolysis of ester "saponification", it is considered as a salt of hydrocarbons. the soap molecule contains the two parts: a polar group   (-coo-na+) and a non-polar group (r-hydrocarbon part). the polar group is called the head and the tail is the non-polar group. the polar group is hydrophilic in nature (water loving) and the non-polar group is hydrophobic in nature (water repelling).the polar/non-polar nature of a substance is useful that it can dissolve the non-polar substances by the polar part and also can dissolve the polar substances by the non-polar part. it commonly used in detergents and soaps.
