And it is refine to each stage, it then can accurately get the size of entire project work amount.
S102：The workload of all kinds of project activities in current project is obtained using history item data sample.
It should be noted that introducing several concepts here：
WBS job analysis：It is the grouping that guiding carries out project elements with deliverable achievement, it concludes and define project
Entire every one layer of more detailed definition represented to project work of decline of working range.
Demand point：It is just divided into the smallest additions and deletions and looks into the function point for changing grade.
Specifically, the scale of project can be estimated with demand point, demand point is to be multiplied by demand by demand number
Difficulty or ease coefficient is added and obtains, if software requirement has defined, demand point, which can have in software requirements specification, to be obtained.Here,
Demand difficulty or ease coefficient：Be divided into it is difficult, in, easily, and each degree has specific numberical range.
Evaluation factor：It is the index for identifying the synthetic operation amount of current project.According to scale of the project, type is cut,
It can be according to certain algorithm（It is obtained according to coverage）Obtain the evaluation factor for newly estimating project work amount.
In this step, the above-mentioned workload that all kinds of project activities in current project are obtained using history item data sample
Including：
For every intermediate item activity：In history item data sample, the workload parameter measurement of such project activity is obtained
Value and the demand of such project activity points, obtain the historical evaluation factor of such project activity；And obtain current project

Correspondingly, being using the method that workload parameter metric and demand points obtain evaluation factor：
Demand count the urgent angle value * technical ability value * technical difficulty value * complexity value of * demand stability value * project, obtain assessment because
Son.
Wherein, the degree of demand stability value mark deviation demand stability criterion value, deviation it is more, demand is steady
It is bigger to determine angle value；The urgent angle value mark of project deviates the degree of degree of urgency standard value, more, the project degree of urgency of deviation
It is worth smaller；Technical ability value mark deviates the degree of technical ability standard value, deviation it is more, technical ability value is bigger；The technical difficulty

The assessment result of project work amount, it is preferable in the embodiment of the present invention, the urgent angle value of demand stability value, project, technical ability value,
Technical difficulty value and complexity value should all the positive numbers that are less than or equal to of value.
For example, demand stability criterion value, the urgent standard value of project, technical ability standard value, technical difficulty standard value and multiple
Miscellaneous degree standard value is 1, is guaranteed in above-mentioned calculation formula in this way, not right when a certain workload parameter metric is in standard value
As a result it has an impact.
Wherein, if demand steadiness parameter X1 value is more than or equal to 1, i.e. demand steadiness parameter X1 is greater than more than 1, says
Bright demand is more unstable, and corresponding workload is bigger, it is preferred that demand stability value is then specially X1-1, that is to say, that is used
The practical bias for deviateing demand stability criterion value 1 of demand steadiness parameter is as demand stability value.
Similarly, if the urgent parameter X2 value of project is less than or equal to 1, that is to say, that when X2 is 1, illustrate that project reaches
To the degree of urgency that should start at once, when project is less than 1, then illustrate that project is more urgent, i.e., than value 0.8 when X2 value is 0.7
Shi Gengjia is urgent, it is preferred that the urgent angle value of project is specially 1-X2.
Based on same reason, the processing of technical ability value, technical difficulty value and complexity value and the demand stability value is former
Reason is consistent, and the embodiment of the present invention repeats no more this.
