Military product development process - transition phase

   The development process of the approved conventional equipment is generally divided into five stages ：
   Demonstration stage （L）、 The programme phase （F）、 Engineering development stage （G）、 Design finalization stage （D） And production finalization stage （P）, Among them, the engineering development stage is the core stage of the whole development work . It is usually divided into the first sample of the project （C） Just like the project （S） Two sub stages .

1、 General principles for the transition of development work

   The basic principle of transferring equipment development to the next stage is to complete the development work specified in this stage before transferring to the next stage One stage development , The development work at this stage has not been completed , We can't cross the development stage and carry out the work of the next stage .
   According to the model development contract and general development requirements , Before carrying out the development work of each stage, we should first formulate the development task statement and detailed work plan of this development stage , Organize and carry out various research and development work according to the research and development task , After the development work , Compile and sort out the summary of development work and other design data specified in the standardization according to the standardization regulations 、 Pattern, etc .
   The model development unit negotiates with the on-site military representative , Confirm that the development work at this stage has been completed , Both sides of the military factory shall conduct internal transition review first , Then apply to the superior competent department , The superior competent department shall organize experts from all parties to hold a formal transition review meeting .
   In the transition review , Experts attending the meeting may raise some problems that remain to be solved , Relevant research and development units must solve these problems within the time limit specified by the meeting , The quality assurance department of the development unit and the on-site military representative shall follow up and inspect , When all the problems are solved , Both sides of the military factory jointly ask for instructions from the competent development department and the user department , After approval, the development work can be transferred to the next stage .

2、 Timing of transition Review

  F turn C Stage
   As a general rule , The demonstration stage and the scheme stage do not need to go through the transition Review , according to 《 Development procedure of conventional weapons and equipment 》, After the approval of the general requirements for the development of type weapon systems , That is to say L turn F Stage time . The designer shall complete the scheme stage
