Calculation of labor input of creation of a software product

Table 4.3 – Qualification of the developer

Duration of work	Coefficient КР
For 2-х years	0,8
2-3 years
3-5 years	1,1-1,2
5-7 years	1,3-1,4
More then 7 лет	1,5-1,6

Costs of work of research of algorithm of the decision:

Q * B

t_u =;

S* KP (4.3)

where Q – the conditional number of operators;

KP – the coefficient depending on qualification of the developer;

B – the coefficient of increase in the expenses, connected to incompleteness of the description and need of specification and finishing, is accepted by B=1,3;

S – coefficient which is defined by complexity of the task, in this case S =85.

644,4* 1,3

t_u =;

85* 0,8

t_u =7,88 hour

Costs of work of algorithm development:

Q

t_р =;

R* KP (4.4)

where Q – the conditional number of operators;

KP – the coefficient depending on qualification of the developer;

R – coefficient which is defined by complexity of the task, in this case R=20.

644,4

t_р =;

20* 0,8

t_р =27,776 hour

Costs of work of compilation of the program for the ready flowchart:

644,4

t_п =;

50* 0,8

t_п =10,31 hour

Costs of work of independent debugging of the program:

644,4

t_отл =;

10* 0,8

t_отл =51,55 hour

Costs of work of documentation preparation in the manuscript:

644,4

t_рук =;

20* 0,8

t_рук =25,776 hour

Costs of work of editing, the printing and design of documentation are calculated on a formula:

t_док = 0,75* t_рук; (4.5)

t_док = 19,33 hour

Summary labor input of creation of the program:

Т = t_u + t_р + t_п + t_отл + t_рук + t_док; (4.6)

Т = 142,62 hour
