3、重要的里程碑、工程工程的本錢、投資回收、工程進(jìn)度進(jìn)展評(píng)審。C、完好的技術(shù)評(píng)審的六個(gè)步驟：預(yù)備-簡(jiǎn)要引見(jiàn)情況-閱讀被審查的文檔-開(kāi)審查會(huì)議-返工-復(fù)查。D、技術(shù)評(píng)審和管理復(fù)審，需求留意軟件錯(cuò)誤的積累和放大效應(yīng)。 4 .軟件工程根底實(shí)際關(guān)于調(diào)研和問(wèn)題定義1、管理者對(duì)管理業(yè)務(wù)的目的什么？管理者的管理需求是什么？管理者單位有哪些部門參與本次的信息化建立，各自部門的作用什么？2、當(dāng)前的管理業(yè)務(wù)系統(tǒng)是如何運(yùn)轉(zhuǎn)的？當(dāng)前管理業(yè)務(wù)系統(tǒng)的組織構(gòu)造、輸入輸出過(guò)程、資源利用情況和日常數(shù)據(jù)處置的情況是什么？當(dāng)前業(yè)務(wù)系統(tǒng)需求優(yōu)化改造的地方是哪些？3、管理者單位要求做成什么樣的系統(tǒng)？做到什么程度？詳細(xì)的要求功能、性能、可靠

4、性、平安性、嚴(yán)密性、界面、資源運(yùn)用、本錢、進(jìn)度是什么？ 5 .軟件工程根底實(shí)際4、調(diào)研方法：a、談判、訊問(wèn)要圍繞軟件目的提出問(wèn)題；b、調(diào)研前預(yù)備好調(diào)查表，調(diào)研表盡能夠詳盡；c、留意搜集客戶運(yùn)用的各種表格、有關(guān)的任務(wù)責(zé)任、任務(wù)流程、任務(wù)規(guī)范、相關(guān)的數(shù)據(jù)規(guī)范、業(yè)務(wù)規(guī)范的相關(guān)文字資料；d、調(diào)研過(guò)程中留意采用情景分析的誘導(dǎo)方式用戶表達(dá)需求；5、調(diào)研的根本戰(zhàn)略：a、首先要確定用戶的軟件開(kāi)發(fā)目的，確定系統(tǒng)的范圍，確定要訪問(wèn)的部門和人員，要了解業(yè)務(wù)，在根本范圍內(nèi)展開(kāi)調(diào)研；b、以業(yè)務(wù)為主線，搞清楚每個(gè)環(huán)節(jié)的流程關(guān)系、涉及部門、輸入輸出項(xiàng)；c、以部門為根底搞清現(xiàn)有業(yè)務(wù)、要填寫的表薄冊(cè)文檔報(bào)表等，其數(shù)據(jù)來(lái)源及去向

5、；d、能否有新技術(shù)和方法可以改良任務(wù)，用戶提出的需求用現(xiàn)有技術(shù)能否能實(shí)現(xiàn)。 6.軟件需求分析需求分析的根本概念需求分析的義務(wù)：提出完好、準(zhǔn)確、明晰、詳細(xì)的業(yè)務(wù)要求，這些要求包括：系統(tǒng)的功能性要求、性能要求、運(yùn)轉(zhuǎn)未來(lái)能夠提出的要求。需求分析的過(guò)程：采用構(gòu)造化的分析方法，面向數(shù)據(jù)流自頂向下逐漸分解求精的進(jìn)展需求分析。需求分析文檔的書寫，主要描畫系統(tǒng)的目的、系統(tǒng)的概貌、功能要求、性能要求、運(yùn)轉(zhuǎn)要求和未來(lái)能夠提出的要求 1 .軟件需求分析概念模型和規(guī)范化，常用的概念性數(shù)據(jù)模型的方法-E-R模型，表示實(shí)體和實(shí)體之間的聯(lián)絡(luò)。 2 .軟件需求分析需求分析圖形工具：層次方框圖、warnier圖、ipo圖。層次

6、方框圖，用樹(shù)形構(gòu)造的一系列多層次矩形框描畫數(shù)據(jù)的層次構(gòu)造；這種方式非常適宜于需求分析階段的需求，系統(tǒng)分析員從對(duì)頂層的信息分類開(kāi)場(chǎng)，沿著每條途徑反復(fù)細(xì)化，直到確定了數(shù)據(jù)構(gòu)造的全部細(xì)節(jié)為止。warnier圖，闡明信息的邏輯組織，它可以指出一類信息或一條信息是反復(fù)出現(xiàn)的，也可以表示特定的信息在某一類信息中有條件的出現(xiàn)。IPO是指構(gòu)造化設(shè)計(jì)中變換型構(gòu)造的輸入Input、加工Processing、輸出Output ，在需求分析階段主要用于主要算法的描畫；該工具主要用于詳細(xì)設(shè)計(jì)階段。 3 .軟件需求分析層次方框圖圖示 4 平安異常處置調(diào)度日志管理 調(diào)度統(tǒng)計(jì)分析消費(fèi)調(diào)度管理子系統(tǒng)日常調(diào)度管理 異常調(diào)度管理
