十八世紀工業革命的推進，使得大量生產(Mass Production)幾乎改變了各產業，為社會帶來大量的財富，隨著網際網路以及社群網站的普及化，大量生產已經無法應付日漸複雜的市場環境，而需要新的商業模式來達到突破。 隨著社群的概念興起，群眾外包的觀念也隨之廣泛應用於各種產業，而不再只限於開放原始碼的用途，逐漸被應用於T-shirt、科技業、雜誌業等等的範疇，舉凡美國Threadless.com、Innocentive等等都是應用群眾外包之成功案例。 群眾外包即是指提供平台供群眾使用，並在該平台上提供創意發想的點子，最終經由一定的表決機制發展成新產品，而非傳統商品化方式─由廠商開發製造完成新產品。 本研究探討群眾外包應用於台灣服飾業者之商品化流程，進而找出關鍵成功策略。為了有效釐清群眾外包商品化之複雜關記以及與群眾之互動細節，採用多重個案研究法，該質化的研究方法可由深度訪談產業專家，以了解發展歷程，並藉由個案廠商的角度，探討群眾外包之關鍵策略。 研究發現，群眾外包之策略是否可行有以下四個檢核點：群眾獎勵機制、仲介網路平台、評選機制以及生產與營運。首先要建立凝聚相同興趣的社群，並提供自由發揮的平台，藉由公正且有效率的評選機制選出欲生產之商品，透過有效率的生產才能順利將商品打入市場。 / As internet become more and more popular, customers become pickier because all of the information is so clear in it.
