On the basis of the embodiment of the invention disclosed above, the invention discloses a method for determining the maximum deliverable demand number in the iteration cycle under the current development team scale based on the maximum value of the construction period of each work project required to be completed by the development team in the iteration cycle and the average consumption of the demand, and the method can comprise the following steps:
step S201: the number of people per group in the current development team size is determined.
Step S202: determining the number of the iterative cycle which can deliver the demand at most under the current research and development team scale based on the number of people in each group under the current research and development team scale, the maximum value of the construction period of each work project needing to be completed by the research and development team in the iterative cycle, and the average consumption of the demand.
As an implementation, the determining the maximum number of deliverable demands for the iteration cycle at the current development team scale based on the number of people in each group at the current development team scale, the maximum number of work periods for each work project that the development team is required to complete in the iteration cycle, and the average consumption of demands may include: calculating the maximum deliverable demand number of the iteration cycle under the current research and development team scale by taking the constraint condition that the total planned construction period of each work project does not exceed the maximum value of the construction periods of each work project needing to be completed by the research and development team in the iteration cycle, the planned construction period of each work project does not exceed a first time period, the product of the consumption of each single construction period of each group of the research and development team for completing a demand and the deliverable demand number of the iteration cycle does not exceed the product of the number of people of the group in the existing research and development team and the planned construction period of the group in charge of the work project;
and the first time length is less than the maximum value of the time lengths of all the work items needing to be completed by the research and development team in the iteration period.
It should be noted that, the total planned time limit of each work item does not exceed the maximum value of the time limit of each work item to be completed by the research and development team in the iteration cycle, the planned time limit of each work item does not exceed a first time limit, the product of the consumption of each individual time limit of each group of the research and development team completing a requirement and the deliverable requirement of the iteration cycle does not exceed the product of the number of people of the group in the existing research and development team and the planned time limit of the group of the responsible work items, as a constraint condition, the planned time limit of each work item can be determined.
For ease of understanding, assume:
the maximum value of the construction period of each work project needing to be completed by the research and development team in the iteration cycle is 15 working days. The research and development team comprises a product design group, a program development group and a program test group, wherein the product design group is responsible for the work of product design, the program development group is responsible for the work of program development, and the program test group is responsible for the work of program test.
The average consumption of demand is: a requirement is completed, a single product design group in a research and development team needs 1 working day, a single program development group needs 4 working days, and a single program test group needs 2 working days.
In the current research and development team scale, 8 production design groups, 10 program development groups and 5 program test groups exist.
The first period was 10 days. The planning time limit of the three works of product design, program development and program test is x days, y days and z days respectively. At the current development team scale, the number of iterative cycle deliverable demands is N.
Then, the constraint is:
x+y+z<＝15
x<＝10
y<＝10
z<＝10
1N<＝8x
4N<＝10y
2N<＝5z
and solving the maximum value of N, namely the maximum deliverable demand number of the iteration cycle under the current research and development team scale.
The solution process may be as follows: the inequality is converted into:
N<＝8x
N<＝2.5y
N<＝2.5z
order: 8x 2.5y 2.5z
The following can be obtained: y-z-3.2 x
Substitution can obtain: x +3.2x +3.2x < (15)
The following can be obtained: x is 2.027
The following can be obtained: n8 2.027 16.216
And because N is an integer, the maximum value of N is 16, and the planning time limit of the three works of product design, program development and program test is 2 days, 6.4 days and 6.4 days respectively.
On the basis of the embodiment disclosed by the invention, the invention discloses a method for determining the minimum value of the number of groups of people in the research and development teams required by delivering a first number of demands in the iteration cycle based on the maximum value of the construction period of each work project required by the research and development teams in the iteration cycle and the average consumption of the demands, and the method can comprise the following steps:
determining a minimum number of groups of the research and development teams required for the iterative cycle to deliver the first amount of demand based on the first amount, a maximum number of work periods of each work project required for the research and development teams to complete in the iterative cycle, and the average consumption of demand.
As an implementation, the determining the minimum number of groups of the research and development teams required for the iterative cycle to deliver the first number of demands based on the first number, the maximum number of work periods for each work project required for the research and development teams to complete in the iterative cycle, and the average consumption of demands may include: determining the minimum value of the number of people in each group in the research and development team required for delivering the first number of demands in the iteration cycle by taking the constraint condition that the total value of the planned construction periods of all the work projects does not exceed the maximum value of the construction periods of all the work projects required to be completed by the research and development team in the iteration cycle, the planned construction period of each work project does not exceed the second time length, and the product of the consumption of the construction period of each group of single people for completing one demand by the research and development team and the first number does not exceed the product of the number of people in the group in the research and development team and the planned construction period of the group in charge of the work projects; and the second duration is less than the maximum of the duration of each work project needing to be completed by the research and development team in the iteration cycle.
It should be noted that the second time period may be the same as or different from the first time period. It should be noted that, in this scheme, the total planned time limit of each work item does not exceed the maximum time limit of the time limits of each work item to be completed by the research and development team in the iteration cycle, the planned time limit of each work item does not exceed the second time limit, and the product of the consumed time limit of each single person in each group in which the research and development team completes a requirement and the first number does not exceed the product of the number of people in the group in the research and development team and the planned time limit of the group in charge of the work item is taken as a constraint condition to determine the planned time limit of each work item.
For ease of understanding, assume:
the maximum value of the construction period of each work project needing to be completed by the research and development team in the iteration cycle is 15 working days. The research and development team comprises a product design group, a program development group and a program test group, wherein the product design group is responsible for the work of product design, the program development group is responsible for the work of program development, and the program test group is responsible for the work of program test.
The average consumption of demand is: a requirement is completed, a single product design group in a research and development team needs 1 working day, a single program development group needs 4 working days, and a single program test group needs 2 working days.
The first period was 10 days. The planning time limit of the three works of product design, program development and program test is x days, y days and z days respectively. The first number is N. And the minimum value of the number of the product design groups in the research and development team required by the iteration cycle delivery of the first number of demands is a, the minimum value of the number of the program development groups is b, and the minimum value of the number of the program test groups is c.
The constraint is then:
x+y+z<＝15
x<＝10
y<＝10
z<＝10
1N<＝8x
4N<＝10y
2N<＝5z
and solving the minimum value of a, b and c.
The solution process may be as follows: the inequality is converted into:
a>＝N/x
b>＝4N/y
c>＝2N/z
then U + a + b + c > -N/x +4N/y +2N/z
Order: x + y + z 15
The inequality is:
U>＝(x+y+z)*(N/x+4N/y+2N/z)/15
(vi) N x [7+ (4x/y + y/x) + (2x/z + z/x) + (2y/z +4z/y) ]/15, U being the minimum of the total number of development teams required to deliver the first number of demands for the iteration cycle;
order:
4x/y＝y/x
2x/z＝z/x
2y/z＝4z/y
the following can be obtained: x y/2 sqrt 2 z/2
x+2x+\sqrt{2}*x＝15
Obtaining by solution: x is 3.398
y＝6.796
z＝4.805
Then: original equation > (N + 7+4+2 \ sqrt {2} +4 \ sqrt {2} ]/15
＝N*[11+6*\sqrt{2}]/15
Since N is constant, N is not made 5
U > < 5 x [11+6 x \ sqrt {2} ]/15 ═ 6.495 (theoretical minimum value)
At this time: a > -N/x-5/3.398-1.471
b>＝4N/y＝20/6.796＝2.942
c>＝2N/z＝10/4.805＝2.081
The reason is that: the numbers of a, b and c are the number of people, so rounding up is needed.
The following can be obtained:
number of people in design group min (a) 2
Number of persons in the program development group min (b) 3
Number of persons in program test group min (c) 3
Namely: in the case where the first number N is 5, the minimum number of research and development teams at this time is: 8 persons.
The planning time limit of the three work of product design, program development and program test is 2.5 days, 6.7 days and 3.4 days respectively.
The method is described in detail in the embodiment disclosed in the invention, and the method of the invention can be realized by adopting devices in various forms, so that the invention also discloses a planning device for an iterative delivery mode, and the specific embodiment is given in detail below.
