They do pretty much overlap, I would even say so much in reality, that there is no need for 2 specific NOC. Purchasers tend to be more type of strategic or commodity purchaser and then operative or logistic purchasers. First one do more setup work and first sampling of the parts and the second ones do more ordering according to the setup conditions and solving day to day issues.
Smaller companies have mixed purchasers (they will do both at a cost of any long term strategy - daily operations are time consuming).
The biggest difference I see there (apart of that strange property purchase) is the purchase of general products (I buy Huggies, Nivea cream or Chrysler spark plugs on my stock and then the seller will be reselling them. I do not buy it according to the specific demand but rather according to the general demands and trends.)
While 1225 first gets the request of the customer (or their production or engineering) and then they try to get to purchase that for the project or request that they got). And also 1225 has a bit more emphasis on the strategic setup (contracts and such).
That is why I called it B to C or B to B relationship.
And apart of 6222 you have also 1523 and 1524 - people dealing with reordering only.
So why do you need so many NOC is beyond me.
Here is how they overlap. I see like 80% of the duties that do overlap and the difference is just a nice wording but not the nature of the job duty tasks.
NO 6222
- 1. Purchase merchandise for resale by retail or wholesale establishments - retail and wholesale is aimed more for general public (B to C relationship is more common here). If there is B to B relationship, it is for so called catalogue parts that you have on stock ready to sell. (which then generates a purchasing request of the same parts for your purchasing team).
- 2. Review requirements of establishment and determine quantity and type of merchandise to purchase
- 3. Study market reports, trade periodicals and sales promotion materials and visit trade shows, showrooms, factories and product design events
- 4. Select the merchandise which best fits the establishment's requirements
- 5. Interview suppliers and negotiate prices, discounts, credit terms and transportation arrangements
- 6. Oversee distribution of merchandise to outlets and maintain adequate stock levels
- 7. Establish and maintain contact with suppliers
- 8. May supervise the work of other retail buyers.
NO 1225
- 1.Purchase general and specialized equipment, materials, land or access rights, or business services for use or for further processing by their establishment - mainly for B to B, you just do not resell whatever is available for the general public but you go and seek parts exactly for your customer (which can be either production to produced according to the released documentation, or the resell of spare parts, but these are purchased on ad hoc demand).
- 2, 3 and 4. Assess requirements of an establishment and develop specifications for equipment, materials and supplies to be purchased - same as 6222, just a bit different wording and a bit more technical review of the demand is underlined here, but in reality you need to know your product regardless what you purchase (at least a bit)
- 5. Invite tenders, consult with suppliers and review quotations - same as 6222 just split in separate lines.
- 5. Determine or negotiate contract terms and conditions, award supplier contracts or recommend contract awards - same as 6222 just split in separate lines.
- 5, 6 and 7. Establish logistics of delivery schedules, monitor progress and contact clients and suppliers to resolve problems - here for a change several tasks form 6222 are merged.
- 5 and 3. Negotiate land acquisition or access rights for public or private use, and may conduct field investigations of properties - all belongs under contracts of purchased products (a product can be anything from paper clip in the office to contractors costs to the building purchase. Depends which commodities are you dealing with). However this is on borderline with the legal department. No idea why they put so much weight on property purchasing (it is just one of many commodities you can purchase).
- 8. May hire, train or supervise purchasing clerks. - same
