Working with producers like farmers and their successors in a practical way has one important advantage : You have to teach efficiently within a limited timeframe. This means: use the simplest definitions and programmes!

Some of the author's works:

In 2024, he analysed the German BayWa Group. The author's research was published under the headline 'Stop the "Three Activities" in IFRS 18'. Later, he researched the terms used by professional company valuers. 
Early in his career, the author was obliged to code business transactions.
In 2001, he revised - with others - a bookkeeping guide that included only plus/minus entries.

The author's first software was 'Zins Intern' (1986),  designed to analyse total interest rates for the most complex savings-and-loan packages. It ran on 32-bit computers.

Author's remarks:

'Self-financing capacity', 'cash flows 1–3', and depreciation as benchmarks were introduced by others. However, he is one of those who calculated cash flows 1–3 from the outset on the basis of adjusted key figures.

The main advantage of working practically with producers such as farmers and their successors is that teaching and consultation must be completed within a very limited timeframe. Therefore, simple definitions and programmes must be used.
