Alchemy (4): mental model of programmers

If the members of a team are all senior programmers , Is it possible to ensure that the quality and efficiency of project development are the best ？ The answer is not necessarily .

If the members of a team are all novices , Whether the development quality and efficiency of the project is “ Novice level ” Well ？ The answer is not necessarily .

Because people's inertia will breed , The broken window effect works silently behind the scenes . If no one in a team takes responsibility , Promote a compact development rhythm , Push forward the progress , Then the quality and efficiency of the project will decline casually .

even to the extent that , Sometimes the more experienced programmers , The more old-fashioned things will appear , Your suggestion will be rejected for various reasons , What happened , Will not be actively resolved . The enthusiasm of active members will also be in such an imperceptible “ Culture ” Is obliterated under the influence of . Some senior programmers seem to have good skills , But the mind is closed (CloseMindness), Clinging to “ I'm right ”,“ This is very simple , I can handle it easily ” This mentality . In this case, the team will pay the ultimate price ,Leader This risk should be identified in a timely manner . It should be understood , Whether senior or not , For one Issue, Can you articulate your solution hierarchically to other developers , Do you have a reasonable modularity problem , Do you have enough coverage tests , Do you confirm your needs with others in a timely manner . These details , It's not something to do , You respect the rules of program development , You know these interactions are just good “ Programming ” One of the . It's like writing code , The implementation of a function consists of several ordered sub steps . If you can use this kind of thinking in your development process , Give Way “ substep ” Be specific , Do not slacken off in carrying out these “ Simple ” Sub step of , Then your development is of quality .

Although the novice's technical level is not senior , There are even many elementary skills that are not familiar with , But good beginners tend to be more open-minded (OpenMindness). Good novices will modestly accept reasonable project scheduling 、 I will actively put what I have in hand issue Exterminate . well Leader Will guide the novice to adjust the priority of the task , Put one Issue【 Disassemble the alarm clock in a clear hierarchy 】, And can 【 By oral 、 written words 、 The chart clearly explains 】, This starts from the protein area to the yolk area , Let the novice keep a moderately tense rhythm to follow up the project . well Leader Be able to identify and predict what difficulties novices will block , And expect this blockage , Do pair programming with novices in time , Hand to hand in the process of solving the blocking problem , Ensure the progress , In the process of solving problems in pairs, novices can learn good programming skills 、 Habit and thought . Such a well coordinated novice team , Sometimes “ The Three Stooges , Zhuge Liang at the top ” The effect of .

Why identify experienced and novice , This is because , You don't recognize the problem , These questions will eat up your precious time . in fact , We should think that , Real senior , Should always keep “ Novice ” The mind of .
