• Takala 2001 Phusavat and Takala 2005 Takala
  1997, describe the relations amount F and R, A
  and L, in a qualitative form
• This article attempts to describe a
  quantification of these variables.

The connection of flexibility F to C, Q, T
C cost T time Q quality
F f ( R, L, A )

• R responsiveness
• "Speed by which the system successfully fulfils
  the unanticipated requirement"
• A agility
• "Speed by with the system adapts to the optimal
  cost structure"
• L leanness
• "Minimalization waste in all responses and
  activities"

• R f(T,Q), L f(Q,C), A f(T,C)
• Starting state of analysis
• -in some moment t1 all variables Q,C,T are 100
  triangle will be always symmetric- META RAL

Pythagoras formula
Responsiveness Leanness Agility

Expression for flexibility F

If the variables Q, C, T are in lt0 100gt,
flexibility is defined in interval lt0 0.66gt.

• F0 if Q, C, T is equal 0
• F0.66 (it means 1000.66) if Q, C, T are equal
  1 (META RLA triangle)

Future research

• Law of cosine for general triangle RAL
• Vector calculation for F f (C,T,Q....)
