It is beneficial to the end user , the customer organization and the development organization to identify and improve the non functional requirements of the product like performance , usability , reusability , availability etc 这才有利于最终用户、客户组织以及开发组织确定并改进诸如性能、可用性、重用性、可行性等非功能性需求。
In the sheep team example , the web services approach satisfied the functional requirements and the standardized enterprise architecture , but it failed to satisfy the non - functional performance and resource utilization requirements 在sheep团队这个例子中， web服务方法满足了功能性需求和标准化的企业体系结构，但是不能满足非功能性需求和资源利用需求。
But while it s all well and good to come up with a new , clever , simpler , prettier , or more elegant approach to solve some problem , if you don t consider non - functional requirements , then your solution may actually be useless 采取一种新颖、巧妙、更简单、更漂亮或更得体的方法来解决某种问题固然很好，但是如果您没有考虑非功能性需求，则您的解决方案可能无法取得
Problems like remoteability and scalability - as well as maintainability , speed , and flexibility to adapt to changing business needs - are nonfunctional requirements that each of us has struggled with at some point when architecting a software system 像远程能力和可伸缩性以及适合于更改业务需求的可维护性、速度和灵活性等这样的问题是我们每个人在构建软件系统时所追求的非功能性需求。
Based on this , we establish some key problems in pse development . for instance , relation of attributions in model , interface , data entry and result output . at last , we finish the prepare system design of developing pse 同时确定了模型各属性的对应关系以及接口、数据输入和计算结果输出等技术问题，分析了利用java编程基础的可能性和对非功能性需求的适用性，完成pse开发的系统设计工作。
Therefore , if requestor response time and message throughput are important non - functional requirements for the application , then consider asynchronous message exchange instead of synchronous exchange to minimize blocking and delays in the requestor s processing 因此，如果请求者响应时间和消息吞吐量是应用程序重要的非功能性需求，那么应考虑使用异步消息交换来代替同步交换以减少请求者阻塞和等待的时间。
Therefore , if throughput and minimizing memory utilization are important non - functional requirements for the application , then consider using a message format that minimizes the amount of parsing time , datatype transformation time , and dynamic memory allocation time 因此，如果对于应用程序来说吞吐量和最小内存占用是重要的非功能性需求，就要考虑使用能够减少解析时间、数据类型转换时间和动态内存分配时间的消息格式。
Therefore , if a service has a large number of concurrent requests and response time and message throughput are important non - functional requirements , then consider managing the number of threads running on a system and scaling the service to run on multiple cpus and computers 因此，如果服务有大量并发请求，而且响应时间和消息吞吐量是重要的非功能性需求，就要考虑控制系统上运行的线程数，并在多个cpu和计算机上运行服务。
The research results can be outlined as following : 1 . based on the analysis of the requirements for process industry , development , implement , and maintaining of software system project are considered . the function and performance specification , which is the aid of software system designing , are shown 本课题的研究结果和内容可概括为以下几个主要方面： 1 )分析了流程工业实时数据库系统的需求背景，从项目开发、实施、维护、质量等角度考虑系统的非功能性需求，系统地分析了实时数据库系统应当具有的功能，并给出了性能指标的要求，明确了系统设计的目标。
In designing the nm protocol , i broke the old way of designing protocol regardless the function or without function . in this new nm protocol , i clearly divide the protocol into two parts : one stand for the function and the other stand for the performance . using the protocol engineering method , i analyzed , designed and validated the protocol in formal methods 在网络管理协议的设计方面，作者突破了传统的将功能性设计和非功能性设计混为一谈直接设计开发的思想，在详细划分功能性和非功能性需求的基础上，有针对性的独立设计和开发了网络管理协议的功能性部分和非功能性部分，并在实现的过程中将两者有机的结合起来使之可以独立亦可联合的工作。
