I want to receive updates regarding this question via email.

Cogs and units sold

Cogs is directly proportional to the number of units of goods sold right? So if we have fewer sales in terms of number of units, the. cOGS should also decrease, correct?

Hi!

"Cogs is directly proportional to the number of units of goods sold right? " --> No, that's wrong! COGS is related to the number of units PRODUCED! Usually it is correlated, but it's still an important distinguishment and it shows whether a candidate is a rigorous thinker or not! 

Cheers, Sidi

P.S.: I see a couple of comments here saying that COGS includes fixed costs. From my view this is completely wrong! Cost of goods sold (COGS) refers to the direct costs of producing the goods sold by a company. This amount includes the cost of the materials and labor directly used to create the good. By contrast, fixed costs such as managerial salaries, rent, and utilities are not included in COGS. Have a look at Investopedia - the term COGS is very well explained there!

P.P.S.: If there is a delta between units produced and units sold, this indicates that the inventory stock is increasing or decreasing!

I don’t understand. In the case direct labour cost is fixed, why are you saying COGS doesn’t include fixed costs?

Direct labour is not fixed. That’s why it is direct! E. g. wages paid on base of units produced. Imagine for example agriculture workers who are harvesting asparagus and are paid based on the total weight of asparagus harvested.

Sorry but what you are saying doesn’t make sense. Direct labor cost simply means the cost is for a worker directly related to the production of a product/service. There is no reason to assume that cost should always be variable

Hi there,

If you sell fewer units, COGS (the direct cost of producing goods or services) should also decrease. However it may not decrease proportionally.

COGS may also include costs like labour, which may be fixed. When the labor cost is fixed, then selling fewer units won’t decrease proportionally the COGS, as the labour cost won’t decrease.

Hope this helps,

Francesco

It is not mandatory.

COGS can be fixed costs, variable costs (as you are expecting), or a mix of both (most likely).

If you provide more context on the specific case - we can comment better

Not proportionally, COGS very often includes some fixed cost (e.g., labour, amortization of machinery) - this portion will not change depending on the number of units sold/produced

Amortization of machinery is COGS? Seriously? Jesus...

Hi there,

Sidi is correct...COGS will change based on units produced.

Five Dysfunctions of a Team
The model of the "Five Dysfunctions of a Team" comes from the business novel of the same name by Patrick Lencioni. The author, an experienced consultant in team development, tells the story of a tech company that was once successful – until the team began to fall apart. Lencioni shows how certain patterns can hinder a team – leading to a real crisis.Especially in study projects, group work, or later in your career (especially in consulting), it’s important to recognize these dysfunctions – and actively address them. Teamwork is more than task division. It thrives on trust, clarity, and real collaboration.Here are the five main dysfunctions – and how to avoid them. The Five Dysfunctions of a TeamLack of Trust: Without trust, little happens in a team. If you hide weaknesses or uncertainties instead of addressing them openly, no real collaboration occurs. Teams that allow vulnerability perform better, learn faster, and use everyone’s strengths. Trust is the foundation – and without it, all problems follow.Fear of Conflict: It might sound strange, but good teams argue constructively. Avoiding conflict often leaves things unsaid, causing tension and frustration. Open and respectful discussions lead to the best ideas.Lack of Commitment: When decisions aren’t made clearly or collectively, commitment suffers. Why should you commit to a goal you didn’t agree on? Open discussions and clear commitments ensure everyone is truly on board.Avoidance of Accountability: Accountability works only when clearly assigned. When no one knows who’s responsible for what, the “someone else will do it” problem arises. Set clear responsibilities and hold each other accountable.Inattention to Results: What matters most is what you achieve together. If personal egos or career goals take over, focus is lost. This is crucial in consulting teams, where results are measurable. Keeping the bigger picture in mind makes all the difference. Actively Addressing the DysfunctionsBuild Trust: Openness, honesty, and vulnerability lay the foundation for trust.Promote Constructive Conflict: Respect different viewpoints and encourage open communication to turn tensions into productive debates.Make Clear Decisions and Commit to Them: Transparent decisions and commitment ensure accountability.Take Responsibility and Demand Accountability: Ensure everyone takes responsibility and holds each other accountable.Prioritize Team Goals: Put the team’s goals first and make sure personal interests don’t hinder collaboration. What Does This Mean for You as a (Future) Consultant?In consulting, success rarely happens alone. Projects are complex, require teamwork, and are often under time pressure. Without trust, suppressed conflicts, or unclear accountability, projects can fail.Lencioni’s model helps you spot these patterns early – and take action. Openness, accountability, respect, and shared goals are not just “nice to haves” but true success factors. Especially in consulting, where you work with many stakeholders.
