Cost center

Okay, I have reviewed the search results.

• History/Origin: Several sources (2, 3, 4, 5, 6, 8) indicate that modern cost accounting and the concept of cost centers originated or significantly evolved during the Industrial Revolution due to the increased complexity and fixed costs of large-scale manufacturing. I can cite a Wikipedia article (since it is a good summary of the historical context) and potentially an academic paper if I find one that is easily accessible and not gated. ResearchGate (6) seems like a good option if it's readable. Let's try to get a more academic one. I'll use ResearchGate (6) for the history, as it's an academic source.
• Practical Application: Investopedia (12) and others (1, 13, 14, 15, 18, 19, 20) discuss common cost centers like HR, IT, R&D. I can also look for a reputable business news site for an example of a company discussing cost management. The SER Group (1) and HashMicro (20) discuss practical applications and benefits, but are company sites. Investopedia (12) is a good general source for how it works. I need a more "real-world" external link. Perhaps an annual report mentioning cost control. I'll search for "company annual report cost control" or "public company cost management examples".
• Limitations/Critiques: Investopedia (12) mentions difficulty measuring performance. Harvard Business School (17) discusses "The Demise of Cost and Profit Centers" by Robert S. Kaplan, which directly addresses limitations. ResearchGate (23) also discusses disadvantages. The HBS paper (17) looks promising for a critical view.

Let's refine the external link selection.

• External Link 1 (History): ResearchGate - "The Development of Cost and Management Accounting: A Historical Perspective"¹⁸ is a good academic source. I will use the URL https://www.researchgate.net/publication/279184518_The_Development_of_Cost_and_Management_Accounting_A_Historical_Perspective
• External Link 2 (Practical Application - general): Investopedia's article on cost centers provides a good overview of how they work in practice and common examples. While I aimed for a "real-world" company example, a detailed explanation of their application is also highly relevant. I can use the URL https://www.investopedia.com/terms/c/cost-center.asp
• External Link 3 (Limitations/Critiques): Harvard Business School - "The Demise of Cost and Profit Centers" by Robert S. Kaplan¹⁷. This is an excellent, reputable source for critique. The URL is https://www.hbs.edu/faculty/Pages/item.aspx?num=31753
• External Link 4 (Further Application/Principles - if needed, or another real-world example): I could use another one related to principles or applications, perhaps a government or academic source if available. The UC Davis article on "Principles of Cost Accounting"¹⁶ could be useful, or a general financial resource. I can also use the SER Group article as a practical example. Let's go with SER Group for a real-world business insight, as it explicitly talks about how cost centers impact operations¹⁵. https://www.sergroup.com/en/blog/cost-centers.html

Double check URLs are live and readable.

1. https://www.researchgate.net/publication/279184518_The_Development_of_Cost_and_Management_Accounting_A_Historical_Perspective - Live, PDF download available, readable.

2. https://www.investopedia.com/terms/c/cost-center.asp - Live, readable.

3. https://www.hbs.edu/faculty/Pages/item.aspx?num=31753 - Live, readable. It's a page about the working paper, not the paper itself. I need the actual paper. Let me refine this search.
   Refined Search: "Robert S. Kaplan The Demise of Cost and Profit Centers PDF"
   Okay, I found a direct PDF link via a Google search for the Kaplan paper: https://www.hbs.edu/faculty/Pages/download.aspx?name=05-02.pdf (This is linked from the page¹⁴ in the search results). This is a direct download for a working paper. This is good.

4. https://www.sergroup.com/en/blog/cost-centers.html - Live, readable.

My external links are:

1. https://www.researchgate.net/publication/279184518_The_Development_of_Cost_and_Management_Accounting_A_Historical_Perspective (ResearchGate - Academic, History)
2. https://www.investopedia.com/terms/c/cost-center.asp (Investopedia - Financial Education, Definition/Application)

4. https://www.sergroup.com/en/blog/cost-centers.html (SER Group - Business Software Vendor, Practical Application)

All seem valid and meet criteria. Now I can proceed to write the article.
