How good programmers face change requirements gracefully

Changing requirements is a headache for many programmers, because the most direct impact of changing requirements is a sudden increase in workload, which is undoubtedly a worse thing for us who have already had a lot of workload. However, we always hear leaders say "customer is God". When customers need to change their needs, as technicians, they must also actively meet the needs of customers, which also brings us greater work pressure. So, as a programmer, how do you gracefully respond to changing needs in order to better fit the needs of your career?
Before putting forward specific suggestions, the author believes that it is necessary to make a more detailed discussion on the demand planning and feasibility analysis of the project development.
In the life cycle of software, requirement planning is an important link. In the process of software project development, if the requirements are suddenly changed, the life cycle of the software will be disrupted, and the development process will fall into an embarrassing situation. There are also many posts on the Internet about complaining about the change of demand. The change of demand is likened to changing the curry beef fried rice to egg fried rice, and then from egg fried rice to tomato and egg fried noodles. Such changes to requirements are tantamount to pushing requirements planning all over again, making the hard work of previous developers in vain. So in order to avoid such a thing from happening, it is necessary to make the system's function "what to achieve" as a firm goal before doing development.
After the "what to achieve" is determined, the "how to achieve it" can be discussed. Experienced programmers can convert changes in customer requirements into adjustments in implementation methods, so as to avoid disrupting their own development ideas. In the process of sorting out "what to achieve", the goals that need to be achieved are standardized into documents that describe complete, clear and standardized descriptions and related performance, and of course, there are various plans for possible changes.
Having said that, how to gracefully respond to change requirements can be transformed into one of the questions of how to be a skilled and experienced programmer.
Technical Chapter - Accurate Demand Assessment and Reasonable Feasibility Analysis
Accurate requirements assessment comes from a deep understanding of requirements, how to transform ordinary people's ideas into programmers' programming ideas, which requires in-depth requirements to the design level. Not only must they politely reject unreasonable designs, but they must also be able to propose alternative and reasonable solutions. All this is done to avoid frequent changes during development. Mr. Chen from Shangxuetang pointed out that feasibility analysis can help us to better fix the demand based on the needs assessment.
The first is technical feasibility: determine that the implementation of the requirements is within the technical capabilities of the team, such as front-end, back-end, server, database developer staffing, and whether there is previous available experience, these are best to list . On this basis, you can start to sort out the architecture of the system to achieve security, maintainability, and scalability. So don't rush to write code, sort out your ideas, and the coding efficiency is higher.
The second is the controllability of risk: what if the requirements change? The best way is to extend the functions and enrich the interface without changing the architecture. Developing the reserved land allows us to deal with it freely during the development process.
There is also high-quality code: neat and beautiful, fully annotated, with good readability and reusability, even without the assistance of documents, it can be checked and modified, which can greatly improve the efficiency of the coding phase in the development cycle.
Experience chapter - calmly and calmly deal with the situations that may arise in the development process.
Calmness and calmness originate from confidence in technology. As a developer, solid technology combined with experience can be used to face various development needs in order to be sharp-eyed.
Avoid blind self-confidence and accurately locate the problem: Do not engage in development to show off your skills, avoid unnecessary obstacles for subsequent changes due to the pursuit of simplicity, such as frequent calls and multi-layer nesting, you need to be cautious. Don't get overwhelmed by your own problems until the customer asks for a change. Therefore, debugging skills are essential for good programmers.
Be good at communication and guide customers: the needs put forward by customers naturally have their reasons, so the goal of communicating with customers is to explore the boundaries of customers' needs. Sensitively capture the customer's demand point, and let the customer become a partner in our development process. Product managers are our comrades in arms, and to a certain extent, we persuade more of PMs. You must know that no software system or information system in the world is perfect, so there is no need to argue with the PM for perfection. Making the change requirement is more of an improvement of the software, so that it can be used in the development process. Cope with ease.
