Implementation of Design and Testing Activities in Agile Development and Its Application Results †. †. Taku Fujii , Masayuki Tsuruharaya. This paper reports implementation and application results of design and system testing activities in an agile method, AMRM, based on 5 phases lifecycle model. AMRM was applied to 2 projects and design qualities, productivity, cumulative defects detected by testing, were measured in those 2 projects to examine the effectiveness of the implementation. A design approach to have multiple detail design and refactoring sessions after the elaboration phase is proven to be effective in giving better design qualities. Also, early application of informal system testing activities is proven to be effective to detect defects in the program codes.. 1. 䈲䈛䉄䈮ㄭᐕ㪃㩷㐿⊒ㅜ਄䈪䈱㘈ቴ䊆䊷䉵䉇ᛛⴚ䈱ᄌൻ䈮ኻ ᔕ䈚䈭䈏䉌㐿⊒䉕ⴕ䈉䈖䈫䉕⋡ᜰ䈜䉝䉳䊞䉟䊦㐿⊒ᚻᴺ 㪲㪈㪴㪃㩷㪲㪉㪴䈫๭䈳䉏䉎䉸䊐䊃䉡䉢䉝㐿⊒ᚻᴺ䈏ឭ᩺䈘䉏䈩䈇䉎㪅㩷䉝䉳䊞䉟䊦㐿⊒ᚻᴺ䈲㪃㩷㐿⊒ᣇᴺ⺰䈱ⷰὐ䈪䈲ⷐ ᳞㪃㩷 ⸳⸘㪃㩷 ታⵝ㪃㩷䊁䉴䊃䈱䉰䉟䉪䊦䉕㊀䈰䈭䈏䉌㐿⊒䉕 ㅴ䉄䉎෻ᓳဳ㐿⊒䉝䊒䊨䊷䉼䈱䋱⒳䈪䈅䉎䈏㪃㩷 ଔ୯䉇 ේೣ䉇䊒䊤䉪䊁䉞䉴䈪㐿⊒ᚻᴺ䉕ቯ⟵䈚䈩䈇䉎ὐ䈪ㅢ Ᏹ䈱෻ᓳဳ㐿⊒䊒䊨䉶䉴䈫⇣䈭䉎㪅㩷 ᧄ⺰ᢥ䈪䈲㪃㩷 ⷐ᳞㪃㩷 ⸳⸘㪃㩷 ታⵝ㪃㩷䊁䉴䊃䉕ㅢ䈛䈩േ૞䈜䉎䉸䊐䊃䉡䉢䉝䉕૞䉍 ਄䈕䉎㪈䉰䉟䉪䊦䉕෻ᓳ㩷㩿㫀㫋㪼㫉㪸㫋㫀㫆㫅㪀㩷䈫๭䈹㪅㩷㩷䉝䉳䊞䉟䊦㐿⊒䈪䈲㪃㩷 ৻⥸⊛䈮䋱࿁䈱෻ᓳ䈱ᦼ㑆䈲㪈 ㅳ㑆䈎䉌䋱䊱᦬⒟ᐲ䈮⸳ቯ䈘䉏䈩䈍䉍㪃㩷 ฦ෻ᓳ䈱ቢੌ ᤨ䈮䈠䈱෻ᓳ䈪૞ᚑ䈘䉏䈢䉸䊐䊃䉡䉢䉝䉕㐿⊒ଐ㗬⠪ 䈮䊂䊝䈪⷗䈞㪃㩷 ឭଏ䈚㪃㩷㐿⊒ଐ㗬⠪䈎䉌䈱䊐䉞䊷䊄䊋䉾䉪䉕ᓧ䉎㪅㩷䈘䉌䈮㪃㩷㐿⊒ଐ㗬⠪䈎䉌䈱䊐䉞䊷䊄䊋䉾䉪䈲ఝ వᐲ䉕⸳ቯ䈚㪃㩷 ᰴ࿁એ㒠䈱෻ᓳ䈱㐿⊒⋡ᮡ䈻䈫⚵䉂 ౉䉏䈩䈇䈒㪅㩷㩷䉝䉳䊞䉟䊦㐿⊒䈱ᄢ䈐䈭․ᓽ䈲㪃㩷㐿⊒ㅜ਄䈪䈱㘈ቴ 䊆䊷䉵䉇ᛛⴚ䈱ᄌൻ䈮ኻᔕ䈚䈭䈏䉌㐿⊒䉕ⴕ䈉䈖䈫䈪㐿⊒ଐ㗬⠪䈮䈫䈦䈩᦭↪䈭䉲䉴䊁䊛䉕ല₸⊛䈚䈎䉅䉺䉟䊛䊥䊷䈮㐿⊒䈜䉎䈖䈫䈪䈅䉎㪅㩷䈚䈎䈚䈭䈏䉌㪃㩷 ታ㓙䈮㐿 ⊒ㅜ਄䈮⊒↢䈚䈢㘈ቴ䊆䊷䉵䉇ᛛⴚ䈱ᄌൻ䈮ኻᔕ䈜䉎䈢䉄䈮䈲㪃㩷䈠䉏䉌䈱ᄌൻ䈮ኻᔕ䈜䉎䈢䉄䈱䊒䊨䉫䊤䊛. 䉮䊷䊄䈱ᄌᦝ䉕ല₸⊛䈮䈚䈎䉅ຠ⾰ૐਅ䉕᜗䈒䈖䈫䈭䈒 ⴕ䈉䈖䈫䈏ᔅⷐ䈮䈭䉎㪅㩷䈜䈭䉒䈤㪃㩷䉝䉳䊞䉟䊦㐿⊒䈱․ ᓽ䉕⊒ើ䈜䉎䈢䉄䈮䈲㪃㩷 એਅ䈱㪉 ὐ䈏⺖㗴䈮䈭䉎㪅㩷㩷 z 䊒䊨䉫䊤䊛䉮䊷䊄䈱ᄌᦝ䉕ല₸⊛䈮ⴕ䈉㩷 z 䊒䊨䉫䊤䊛䉮䊷䊄䈱ᄌᦝ䈮䉋䉎ຠ⾰ૐਅ䉕㒐䈓㩷㩷䉁䈢㪃㩷䉝䉳䊞䉟䊦㐿⊒䈪䈲㪃㩷 ৻⥸⊛䈮ᄌൻ䈻䈱ኻᔕ 䉕㊀ⷞ䈜䉎䉅䈱䈱ᦨ⚳⊛䈮䈬䈱䉋䈉䈭ᯏ⢻䈏ታ⃻䈜䉎䈎䈫䈇䈉⷗ㅢ䈚䉕㐿⊒ೋᦼ䉇㐿⊒ㅜ਄䈪㐿⊒ଐ㗬⠪䈫 ⹤䈚ว䈉䈖䈫䉕Ⓧᭂ⊛䈮ផᅑ䈚䈩䈇䈭䈇㪅㩷䈚䈎䈚䈭䈏䉌㪃㩷 ໡ᬺ⊛䈭㐿⊒䉕ᗐቯ䈚䈢႐ว䈮䈲㪃㩷 ᦨ⚳⊛䈮䈬䈱䉋䈉䈭ᯏ⢻䈏ታ⃻䈜䉎䈎䈫䈇䈉⷗ㅢ䈚䈏䈭䈇䈫㐿⊒䈏ᛚ⹺ 䈘䉏䉎䈖䈫䈲࿎㔍䈪䈅䉎㪅㩷䈜䈭䉒䈤㪃㩷䈖䈱䉋䈉䈭⷗ㅢ䈚䉕 ឭଏ䈜䉎䈖䈫䈏䉝䉳䊞䉟䊦㐿⊒䈱㪊 ⇟⋡䈱⺖㗴䈫䈭䉎㪅㩷䈖䉏䉌㪊䈧䈱⺖㗴䉕⸃᳿䈜䉎䈢䉄䈮㪃㩷 ╩⠪䉌䈲䉝䉳䊞䉟䊦㐿⊒ᚻᴺ䈮એਅ䈱㪊䈧䈱䊒䊤䉪䊁䉞䉴䉕ዉ౉䈚䈢㪘㪤㪩㪤㩷㩿㪘㪾㫀㫃㪼㩷㪤㪼㫋㪿㫆㪻㩷㪩㪼㫀㫅㪽㫆㫉㪺㪼㪻㩷㫎㫀㫋㪿㩷㪤㫆㪻㪼㫃㫀㫅㪾㪀㪲㪊㪴䈫䈇䈉㐿⊒ᚻᴺ䉕ឭ᩺䈚䈢㪅㩷㩷 z 䊤䉟䊐䉰䉟䉪䊦⋡ᮡ㩷 z ද⺞⊛䈭⸳⸘䊝䊂䊥䊮䉫㩷 z 䊁䉴䊃䈱⥄േൻ㩷㩷 એ㒠䈱┨䈪䈲㪃㩷䉁䈝㪘㪤㪩㪤䈱᭎ⷐ䉕⺑᣿䈜䉎㪅㩷 ᰴ 䈮㪘㪤㪩㪤䈱⸳⸘૞ᬺ䉕ౕ૕ൻ䈜䉎㓙䈮⠨᩺䈘䉏䈢䋲. † (ᩣ)䉥䊷䉳䉴✚⎇㩷 ᛛⴚㇱ䉸䊐䊃䉡䉢䉝Ꮏቇ䉶䊮䉺䊷. −89−.
