1) Leica operates in the competitive camera industry. New entrants are easy but brand loyalty helps Leica. Suppliers have medium power while buyers have strong power and are price sensitive in the digital age. Substitutes are weak.
2) Leica's market share declined after 2005 while competitors like Nikon and Canon grew their digital offerings. Leica is known for high quality lenses and brand image but struggles with the shift to lower priced digital cameras.
3) Leica's net income turned to losses after 2002 and expenses exceeded sales initially, though profits improved after 2005, as Leica implemented new strategies to adapt to digital trends.
