    --- tags: hw --- # 讀後感想 <因為自動飲料機而延畢的那一年> ## 大綱 - 共有 23 個篇章,主要在敘述作者在大四那年找了兩人一起合作開發自動製作手搖飲料機器的故事。 - 平時作者想法眾多,而且也參加過去許多競賽與經驗,打算創業開公司,於是提出做一個自動飲料機。從一開始滿腔熱血的提出點子,他們先一步步有系統性地分析一些器具的機構,如落杯器、冰塊的影響,主動利用學校及附近的商家,將其實作出來,但也是在過程中漸漸體會到現實面的問題,實作的器具不如預期、金錢、時間等等,而最大的困難為是放冰塊的部分,雖然作者和他的夥伴不斷嘗試不同的方法及測試,用漏斗、篩子,亦或彈簧的旋鈕,但還是無法順理解決,很多想像中很容易,但現實中卻有天差地別的結果。 - 屋漏偏逢連夜雨,團隊中的一人要出國,重重打擊已經精疲力竭的作者,開始懷疑自己當初的決定,也十分沮喪,不知道該怎麼繼續往前。這時卻剛好有個機會跟 jserv 聊一聊,給予他一些建議與開導,而後也與另一個同伴討論後,才漸漸重新找回目標,一步步接著往下做,也還是每個部分都會遇到問題,一一化解後,最後終於順利完成。 ## 心得 - 當去年第一次看到這篇文章時,我澎湃同感油然而生,想到去年冬天也是硬著頭皮,完成系上必修課程微算機的聖誕專案,雖然遇到的困難相比之下小很多,但是文章中的作者總有感同身受,彷彿就是那時自己。 - 前年有堂必修課程叫微算機,期末要交上一份期末專案,因為剛好是上學期,所以老師有提供一個主題叫聖誕專案,利用 MSP430 實作跟聖誕節相關的專案。 - 那時我主動去尋找六個人組隊(因為最多七個人),雖說人數上比較多,但是實作時間相對來得短,老師公布組別到死線,只剩下一個月半左右,立馬開第一次會討論要做什麼東西。我還記得當時我們天馬行空討論的洋洋灑灑的,想像圖畫得很漂亮,說要用透明的壓克力做的很大的三角錐體,但是在我跑到壓克力店跟老闆說我們要 150*150 的壓克力板,老闆按按計算機竟然說要快兩萬,而且説如果要搭起斜面,這個太大,要很厚才不會破掉,但是這樣就會很重,很危險,更何況黏接處要特別做處理,直接被老闆打臉打到腫腫的。當初討論的興高采烈,而且心想一定可以做出來讓老師嚇一跳,結果根本就是我們不懂現實,回去全部從頭討論。 - 而且我不免不認同等待硬體和材料的時間會是一個非常大的成本,我們當時訂個木材竟然都要三四天才能拿到,若是一些特殊的元件,甚至會等到三四個禮拜,明明我們的時間就已經很短了,卻要一直等待材料才能推行進度,無形也這也變成一個很大的壓力,因為每次定材料都要拿捏好數量,寧可多不要少,但是多太多,金錢上又會不允許,而且也要先思考到之後可能會需要或使用到的東西。我有聽說某一組,訂購了較高強度的雷射光組,但是等了一個月都還沒送到,他們只好直接騎摩托車去高雄物流中心拿... - 不過總整來看,雖然作者團隊真的是遇到太多困難,而且多數並不好解,但是很佩服他們沒有放棄,這樣堅持不懈,還深入分析問題的去尋找可行的方式,如果是我可能會直接放棄一些部分,而且當時我們時間真的不夠,很多決策當天晚上就要有答案,要或是不要採用,也因此捨去了蠻多東西,妥協了很多事。 - 但是我自己覺得在某些地方,作者真的有點過於追求完整,現在很多領域強調快速開發,雖然我也沒有非常了解,但是像資源和時間都有限的狀況下,這時應該要更認真看待 MVP(Minimum Viable Product;最小可行產品)這件事,雖然他有意識到,實作出來的產品一定要能幫店家省掉至少一個人力,但是這個面向可以很多,未必卡在處理冰塊這件事上會是好的現象,不過我相信經過這件事,作者學到的不只是一些實作的技巧,更多應該是不同層面在串連時的技巧和經驗。
