Basically, it’s getting important stuff done well enough in a reasonable amount of time.  Key words: important, well enough, reasonable.  If your output is high, but it’s crap, you’re not being productive.  If you’re being a perfectionist (i.e., aiming for an impossible goal), you’re not being productive.  If your work is taking oodles of time to produce because you’re procrastinating or not taking initiative or being a perfectionist, you’re not being productive. 

What is Productivity?

4

How do you know if you’re productive?  It’s really a judgment call.  You have to know the value of the task relative to everything else you have to do, or whoever else you are working with.  Tip: To keep the first two elements in balance, focus on time.  It's finite and everyone has the same amount. 

How Do We Know?

Deadlines Work…

Productivity is literally our middle name. More importantly it is our passion, our mission; it's why we get up in the morning.

The Human Productivity Lab aims to elevate productivity to an art and a discipline.

Future success in the accelerating global market will require that enterprises develop a pragmatic focus on continual increases in productivity.

Measurement of Productivity 　　　 Indicator of Productivity [ P/ hr ]

　　　 Production [ P ]　　　 = N (kg, or ton) / hr 　　　　　　　　　　　　 × ( y × w × s ) × Hr

where, N value : no. of outputs when y = w = s = 1, Hr = 1

7

Where; ~ in average for unit period ~

　 Yield Rate[ y ]

　　　　　　 (no. of good finished)

　　 = 　　　 (no. of good finished + defects/rejects)

　　　　 　　 　　　　　 exp. 　　　　 95 pieces(95 kg)

　　　　　　　　　　　　　　　 100 pieces(100kg)

　　　　　　　　　 　　　　 y = 0.95

8

Working Rate ［ W ]

(actual working hours) =

(scheduled working hours)

exp. 650 hr ÷ 720 hr 　

w = 0.902

9

Speed Rate [ s ]　 　　　　　　　　　　　 (actual speed)

　　　　　　　　　　　　＝ 　

　　　　　　　　　　　　　　　　 (max. speed in design)　　　　　　　　　　　　　　 speed: including machine, hand-work, other operations in processes

　　　　　　　　 exp. 85 pieces(85 kg) / hr 　　　　　　　　　　　　 100 pieces(100kg) / hr 　　　　　　　　　 S = 0.85

10

Hr: Total scheduled hours

for unit period, such as,

one order from customer

　　 Exp. 　　　 24 hr × 30 days

　　　　　　　　　　　　　　 Hr = 720 hr

11

Productivity ［ P/ hr ] Calculation

Exp. When No. of Products is manufactured for 1oo hours in case 30 pieces/ hr as designed capacity,　　　 with the above-mentioned y, s, w

a. Production is calculated below, [ P ] : 30×0.90×0.85×0.95 ×100 = 2180 Pieces

b. Productivity is calculated below, [ P/ hr ] : 2180 ÷100 = 21.8 Pieces/ hr

c. Productivity rate is calculated below,　 [ P/ hr ]/ N×100(%): 21.8÷30 ×100 = 72.7(%)

12

Points to achieve high Productivity a. Enhance y by operating in the optimal conditions according to operational manuals. Enhance y by reducing any chronic errors on products. b. Enhance s by preventing machines from breakdown, small stoppages according to maintenance manuals. Enhance s by reducing the waiting time between processes.

c. Enhance w by eliminating any waste of time.

13

Data collection A. Factors for y a. Identify the scheduled number of good-finished products based on customer’s order b. Count the actual number of good-finish products and defects/ rejects

through whole production

B. Factors for s a. Identify the designed speeds on machines and hand-works b. Measure the actual speed on each item through whole production and

calculate the total speed per unit product

C. Factors for w a. Identify the scheduled hours calculated by the ideal conditions without breakdown time of machines and loss times of breakdown time of machines and loss times of other operations b. Measure the actual hours on each operation through whole production and calculate the total hours per unit product

14

Application Exp. 1. Indicator to measure the difference between before and after any action for improvement

2. Indicator to identify the bottle-neck and the critical items among processes, when the measurement on each factor will be done
