Cost Models For Purchasing
Developing Cost Models is a fundamental professional purchasing skill Category Supplier Specific Item Specific
Effective cost models are needed for all approaches to Purchasing Adversarial, Strategic , Collaborative.
Best practice suggests that providing training to make cost modeling a core skill for Category Managers and Senior Buyers, with support as needed from a small number of “experts,” ultimately produces better and more sustainable results than creating a large centralized purchasing cost group.

Cost Models For Purchasing
Purchasing cost models do not need to be as complex and drill as far down into detail as traditional Cost Accounting models
Simple is better – focus on most important elements and drivers that you can actually get quality information for.
Dive into the marketplace to gather information Visits to multiple suppliers factories Industry trade events and seminars Formal and informal discussion with suppliers Lots of free information on web Look for people with long industry experience in a category that may have
been downsized but still have deep knowledge. Pay them something but could real value.
Use formal consultants as a last, high priced, resort.

Cost Drivers Broad Categories(Examples)
Adding Cost Drivers enables “what if” and more Strategic Analysis
Technology Operations Location Quality Service Level Competitive Landscape Logistics Capabilities Energy
Between categories specific drivers would change For Example Energy: Data Center concern is access to free cooling options
Semiconductor Fab concern would be reliable uninterrupted power
Steps to Create Models
1. Conduct companywide spend analysis and identify categories of spend. Typically grouping by supplier industry or technology is best.
2. Establish you total cost for each category including shipping, maintenance, service, training etc.
3. Build category models with cost drivers – take advantage of free publically available information or only for very critical categories consider paying for an industry report
4. Apply models for step 3 to your current and potential suppliers
5. Build most detailed specific service or product models for your most critical items

Where to prioritize
Cost Reduction as the GoalFocus on the high cost categories where you
currently do not have many options.
Engaging Suppliers to drive your growth and/or reduce risk as the Goal Look at how each category of spend can add
value to your most strategic business units and focus on those categories
Samples
CPOs should establish basic format and process to facilitate training and easier sharing of information within organization
Samples presented as charts which might be final product for presentation
Basic work of models takes place on relatively simple excel spreadsheets
Taken out of context and without good input even the most perfect conceptual cost model is of little value. Therefore, strive to keep things as simple as they can be.
