CMMI評(ping)(ping)(ping)(ping)(ping)(ping)估(gu)(gu)(gu)(gu)(gu)(gu)(gu)(gu)的(de)依據雖然(ran)說是(shi)CMMI模型(xing)，但(dan)是(shi)很多評(ping)(ping)(ping)(ping)(ping)(ping)估(gu)(gu)(gu)(gu)(gu)(gu)(gu)(gu)師(shi)對模型(xing)的(de)理解(jie)并不(bu)(bu)完(wan)全一致，一定程度上還是(shi)依賴(lai)評(ping)(ping)(ping)(ping)(ping)(ping)估(gu)(gu)(gu)(gu)(gu)(gu)(gu)(gu)師(shi)個人的(de)主觀判斷。筆者(zhe)參(can)與(yu)過(guo)幾十(shi)個評(ping)(ping)(ping)(ping)(ping)(ping)估(gu)(gu)(gu)(gu)(gu)(gu)(gu)(gu)后發現(xian)，幾乎每個評(ping)(ping)(ping)(ping)(ping)(ping)估(gu)(gu)(gu)(gu)(gu)(gu)(gu)(gu)師(shi)都有其自己的(de)特點(dian)和關注(zhu)點(dian)。因此(ci)(ci)評(ping)(ping)(ping)(ping)(ping)(ping)估(gu)(gu)(gu)(gu)(gu)(gu)(gu)(gu)時能夠(gou)摸清評(ping)(ping)(ping)(ping)(ping)(ping)估(gu)(gu)(gu)(gu)(gu)(gu)(gu)(gu)師(shi)的(de)特點(dian)對順(shun)利(li)通過(guo)評(ping)(ping)(ping)(ping)(ping)(ping)估(gu)(gu)(gu)(gu)(gu)(gu)(gu)(gu)至關重要。而企(qi)(qi)業一般沒有評(ping)(ping)(ping)(ping)(ping)(ping)估(gu)(gu)(gu)(gu)(gu)(gu)(gu)(gu)師(shi)資源，對評(ping)(ping)(ping)(ping)(ping)(ping)估(gu)(gu)(gu)(gu)(gu)(gu)(gu)(gu)師(shi)知之甚(shen)少，cmmi認證(zheng)評(ping)(ping)(ping)(ping)(ping)(ping)估(gu)(gu)(gu)(gu)(gu)(gu)(gu)(gu)機構，因此(ci)(ci)企(qi)(qi)業自己找評(ping)(ping)(ping)(ping)(ping)(ping)估(gu)(gu)(gu)(gu)(gu)(gu)(gu)(gu)師(shi)進(jin)行(xing)評(ping)(ping)(ping)(ping)(ping)(ping)估(gu)(gu)(gu)(gu)(gu)(gu)(gu)(gu)，存在很大的(de)風險。而一般當評(ping)(ping)(ping)(ping)(ping)(ping)估(gu)(gu)(gu)(gu)(gu)(gu)(gu)(gu)師(shi)對企(qi)(qi)業實施CMMI情況(kuang)不(bu)(bu)了解(jie)的(de)情況(kuang)下(xia)，cmmi認證(zheng)，是(shi)不(bu)(bu)會同(tong)意進(jin)行(xing)評(ping)(ping)(ping)(ping)(ping)(ping)估(gu)(gu)(gu)(gu)(gu)(gu)(gu)(gu)的(de)。咨詢公司因為(wei)長期和評(ping)(ping)(ping)(ping)(ping)(ping)估(gu)(gu)(gu)(gu)(gu)(gu)(gu)(gu)師(shi)合(he)作(zuo)，對評(ping)(ping)(ping)(ping)(ping)(ping)估(gu)(gu)(gu)(gu)(gu)(gu)(gu)(gu)師(shi)都非(fei)常了解(jie)，評(ping)(ping)(ping)(ping)(ping)(ping)估(gu)(gu)(gu)(gu)(gu)(gu)(gu)(gu)師(shi)對咨詢顧問也非(fei)常信任，因此(ci)(ci)咨詢顧問能夠(gou)找到合(he)適(shi)的(de)評(ping)(ping)(ping)(ping)(ping)(ping)估(gu)(gu)(gu)(gu)(gu)(gu)(gu)(gu)師(shi)為(wei)企(qi)(qi)業評(ping)(ping)(ping)(ping)(ping)(ping)估(gu)(gu)(gu)(gu)(gu)(gu)(gu)(gu)，保證(zheng)評(ping)(ping)(ping)(ping)(ping)(ping)估(gu)(gu)(gu)(gu)(gu)(gu)(gu)(gu)的(de)順(shun)利(li)進(jin)行(xing)。

CMMI四(si)級(ji)(ji)(ji)，量(liang)化級(ji)(ji)(ji)。在(zai)量(liang)化管(guan)理級(ji)(ji)(ji)水(shui)平(ping)上(shang)(shang)，所有第(di)三級(ji)(ji)(ji)的(de)要求都已經達(da)到，另(ling)外(wai)，軟(ruan)件組織(zhi)的(de)項(xiang)目(mu)管(guan)理實(shi)(shi)現(xian)(xian)了數字(zi)化。通過數字(zi)化技術來(lai)實(shi)(shi)現(xian)(xian)流程的(de)穩定性，實(shi)(shi)現(xian)(xian)管(guan)理的(de)精度，降低項(xiang)目(mu)實(shi)(shi)施在(zai)質量(liang)上(shang)(shang)的(de)波動。CMMI五級(ji)(ji)(ji)，優(you)化級(ji)(ji)(ji)。在(zai)優(you)化級(ji)(ji)(ji)水(shui)平(ping)上(shang)(shang)，所有第(di)四(si)級(ji)(ji)(ji)的(de)要求都已經達(da)到，cmmi認(ren)證(zheng)評估，另(ling)外(wai)，軟(ruan)件組織(zhi)能(neng)夠充(chong)分(fen)利用信息資料，對(dui)軟(ruan)件組織(zhi)在(zai)項(xiang)目(mu)實(shi)(shi)施的(de)過程中(zhong)可能(neng)出現(xian)(xian)的(de)次品予(yu)以預防。能(neng)夠主動地改善流程，運用新技術，實(shi)(shi)現(xian)(xian)流程的(de)優(you)化。

開發(fa)和(he)應用CMMl的(de)主要原因(yin)有(you)三(san)點：一(yi)是軟(ruan)(ruan)件(jian)(jian)項目的(de)復(fu)雜(za)(za)性的(de)快速增長(chang)使過(guo)程(cheng)改進的(de)難度增大(da)，二(er)是軟(ruan)(ruan)件(jian)(jian)工程(cheng)的(de)并行與多學科組合，三(san)是實現過(guo)程(cheng)改進的(de)效(xiao)益。解決軟(ruan)(ruan)件(jian)(jian)項目的(de)過(guo)程(cheng)改進難度增大(da)問題。CMM成(cheng)(cheng)功實施(shi)以后，極大(da)地提高了軟(ruan)(ruan)件(jian)(jian)企(qi)業(ye)的(de)開發(fa)效(xiao)率(lv)和(he)軟(ruan)(ruan)件(jian)(jian)產品(pin)的(de)質量，從而也提高了軟(ruan)(ruan)件(jian)(jian)產品(pin)的(de)可靠性和(he)軟(ruan)(ruan)件(jian)(jian)產業(ye)的(de)信譽(yu)，這樣人們就(jiu)對軟(ruan)(ruan)件(jian)(jian)寄予了更大(da)的(de)希(xi)望。人們希(xi)望軟(ruan)(ruan)件(jian)(jian)能夠完成(cheng)(cheng)更多、更大(da)、更復(fu)雜(za)(za)的(de)任務。
