Hints continuous improvement

Very careful assessment of the demand for the product shall be made before planning to manufacture higher quantities by the plant and adding more products in the future. The product quality shall be continuously improved upon, and its usefulness for more applications shall be found out. Feedback shall be obtained from clients by regular meetings to get a hint whether the product may become obsolete due to better/cheaper products likely to enter the market. However, there shall be no compromise on safety, environmental pollution control, product quality, and efficiency of operations during expansion of capacity or while adding new products. 

Still, there was a discrepancy of0.12 eV that continued to bother Hylleraas when he returned to Oslo in 1928. Hylleraas considered this discrepancy a serious problem. On the one hand, attaching great importance to the variational principle, he was happy to see that his calculations approached the experimental number from the right side. On the other hand, he could not see how further extensions of the Cl expansion could improve the situation much, hinting at a limit of 24.49 eV [3] - still...
