‘ ‘ But how many they are the enough indices for a good analysis of the reality of the companies. They affirm Santos and Barros (2005, P. 167) that: in the truth an accurate number of quotients does not exist that reflects a good analysis. Everything also depends on the necessity of the consuming user/of the information and of the depth with which if it wants to execute the work.
Matarazzo (2008), sample that has a limit between useful information, that if give to one agile interpretation and with acceptable precision and an enormous amount of data placed in enfadonhos reports and without sensible greater. When the amount of calculated countable indices is increased, does not increase the number of useful information proportionally. This can be shown more clearly by the graph to follow: Amount of GRAPHICAL 2 information P 1 251215Quantidade of indices 1? Qtde. of infomaes x qtde. of indices Source: MATARAZZO (2008, P.
149) We see that when the amount of indices increases of two for five the amount of information that if can take off in an analysis of these indices is X; however, when the amount of analyzed indices passes of 12 for 15, the amount of information is X/2, that is, it does not increase proportionally as if it could wait, in contrast, diminishes. According to Matarazzo: ‘ ‘ the evaluation of the company through indices obligatorily demands the comparison with standards and the setting of the importance relative of each ndice.’ ‘ (2008, P. 147) It is exactly what n 36,601/96 of the State Government happens in the Table of Contbeis indices (TIC) of the Decree.
