Four commonly used R & D models

In software engineering , The R & D model combines the project development process 、 Patterns and conventions of team R & D personnel and collaborative tools and systems . Several R & D models we often contact and use are ： Waterfall model 、 Incremental model 、 Iterative model / agile development 、 Spiral model . among ,

Waterfall model ： It is applicable to software systems whose requirements can be determined in advance and are not easy to change , Usually, this kind of project has a long cycle 、 It's a brand new project , And it needs to be delivered completely at one time . In outsourcing development projects , Especially suitable for waterfall model .

Iterative model / agile development ： With a more frequent rhythm and shorter update release cycle , Continuously update and iterate the products . For example, the early entrepreneurial team launched the first version MVP Try and error quickly and at low cost ; The developing entrepreneurial team has weekly rapid iterations guided by user needs or responding to market needs 、 Small step run . I think ,SaaS Products and ToC Class products are suitable for using iterative models , Continue to give users a better product experience .

Incremental model ： The incremental model is applicable to software systems with relatively stable user requirements , In other words, once the software system is released and delivered, it will be deployed and updated again, which is a very expensive project . for example , in the light of ToB Privatize the deployed project system , Or install it on the customer's intranet 、 Or the client software application on the customer's local computer . Incremental model , It is especially suitable for software systems with obvious version numbers . For example, these examples ：PhalApi Open source interface framework v2.18、 Interface master v3.13、YesDev Private deployment .

Spiral model ： It is a hybrid model of the above models , At the same time, risk control is introduced .

In terms of project collaboration ,YesDev More concise 、 More real time 、 Better to use .

Collaboration of individual projects

YesDev Based on the iterative model of agile development , It can effectively coordinate multiple short, smooth and fast projects in parallel . It also supports waterfall model 、 Incremental model 、Scrum And other research and development models .

When creating a project , You can choose the default project collaboration template , Start a new collaboration project . Default agile project template , fit 1~2 Weekly product iteration .

You can also work in the background of enterprise management , Configure your own common project templates .

After the project is created , You can efficiently coordinate multiple projects in parallel . stay YesDev, You can quickly switch to different projects , And the item menu on the left , You can quickly see the aggregated information of each project and the latest research and development trends updated in real time . You can create many projects , You can also arrange many projects , But how many projects can the team work together and in parallel at the same time ,YesDev The project aggregation information will tell you the most true situation .

In every project collaboration , The work items we perceive and often use are ： demand 、 Tasks and defects . Some students may ask , Is there any difference between the three ？ Simply speaking ,

• demand （ product -> Research and development ）： It is proposed by the product , New functions that need to be implemented and developed 、 New goals ;
• Mission （ Research and development -> Research and development ）： It is evaluated by technical R & D personnel , In order to complete the above requirements, we need to invest time and complete specific work ;
• defects （ test -> Research and development ）： It is a quality problem found and raised by testers during product acceptance .

therefore ,YesDev It provides requirements planning for project collaboration 、 Demand scheduling ability ：

Provides task collaboration 、 Agile kanban ：

Of course, there is the ability to track defects .

Collaboration of technical projects

YesDev There is another feature , It can not only manage your product requirements project , You can also manage your technical projects at the same time .

Technical projects , It refers to those initiated and proposed by the technology itself , Refactoring that does not aim to achieve business product functions 、 research 、 performance optimization 、 Technology system construction 、 Technological innovation and other projects .

Technology projects also have a big feature , Generally speaking, there is no need for test intervention , There may also be no need to publish business systems . So , In order to better distinguish between technical projects and business requirements projects , Can be in YesDev establish 2 Different working groups . One is the product research and Development Working Group , The other is the internal working group of Technology .

And then , When creating a new project , You can choose to use 【 Technical projects 】 Project template , You can also use your own customized project template . meanwhile , Adjust the color of the item to green or other colors .

Browsing 、 When collaborating and managing technical projects , The team should know ：

1、 Technical projects are compared with demand projects , There is no need for a clear time schedule , Usually, it will give way to the demand project ;

2、 Technical projects , Generally, there is no need for testers to intervene ;

3、 Technical projects , The demand initiator comes from within the technology , Products usually don't care about specific implementation ;

4、 Technical projects , Technical research is needed 、 Compile necessary technical documents and sort out relevant project materials ;

5、 Technical projects , R & D resources and time occupied , Need to synchronize other departments and report to the superior / Boss .

Project management

For technical managers , We must pay attention to both business demand projects and technical projects . If you are busy doing demand projects all day , The technical morale of the R & D team is low 、 Team growth is not obvious ; If you only do technical projects , Then the business needs are not fully guaranteed and even the research and development are disconnected . Therefore, we should coordinate and parallel the two , It's an art , It is also a project .

As a project manager , Or project leader , Need to manage multiple projects at the same time , When you are responsible for the whole , have access to YesDev Of 【 Project set 】.

One way , You can create a new project set , Then associate the existing project .

Another way , Among the major projects you have , Turn on add 【 Project set 】 modular , Then carry out project association and management .

The management effect of the project set is similar to the following ,

Commonly used 、 Rich project plug-ins

YesDev Similar to “confluence”, because YesDev Provides a wealth of project plug-ins , You can choose according to the size of your project 、 Different types of projects and participating members , Add more project plug-ins at any time .

For example, common project plug-ins , There is a project burnout map , You can see the daily project progress and remaining working hours , So that the team can launch an iterative sprint and plan the delay risk in advance .

Example 1： The development plan is just a good burnout diagram .

Contrast examples 2： The development plan is obviously ahead of the planned delivery time .

During the project report , You can use the schedule ,

You can also use the project report automatically summarized by the system , There are detailed project reports , for example ： Development schedule 、 List of requirements 、 Schedule 、 Task list 、 Problem list, etc , Can send email , You can also export Excel file .

Export project report Excel After the file is opened, you can see ： Project scheduling 、 Project requirements 、 Project tasks 、 Project questions . One copy Excel file , Fully grasp the latest project progress 、 Risks and plans .

Project brain map , It is in the way of thinking brain map , Help you summarize the overall situation of the project . From needs to tasks , Pay attention to both progress efficiency and project quality .

There are more commonly used project collaboration plug-ins , Can enter the YesDev Check use freely .

How do entrepreneurial bosses do a good job in cost accounting of R & D projects

Last , We start from the entrepreneurial boss , Or take the overall income of the project as the end , How to use YesDev To help you analyze 、 Evaluate and review , After all, I did this outsourcing project , Will you lose money in the end , If there is profit , What's the profit .

First step , After project creation , Let technology developers , Evaluate and register task man hours according to the customized needs of the project .

such , We can get in order to complete this project , How many man hours are needed .

The second step , In the background of enterprise management , Input the employment cost of each R & D personnel .

The third step , Enter the expenditure and income of the project .

Step four , Finally, in the project cost accounting , View the overall profit and loss of a single project or multiple projects .

such , You can see the specific R & D cost of the project 、 Expense and profit bills .
