Africans work in Small Organizations

This seems to be bad for income per capita

An Organizational Lens to Study Development

Development is about establishing large, well-run organizations

• Agriculture

• Manufacturing

• States/Government Agencies

• Military

Where does knowledge/ability to run large organization come from?

Bangladesh Garments

Bangladesh Ready-Made Garment Sectors

• Second largest export of garments (after China)

• 3000+ (mostly) domestically owned factories,

• … employing 4 Million workers,

• Approx. 40% of all manufacturing jobs

Expected to rise further, given low wages and ample margins to increase productivity (far below international standards). Yet

• 75% increase in minimum wage

• Significant instability, and …

Many observers expect Africa’s role to increase in near future !

Why Garments ?

Essentially every country that has ever industrialized started acquiring manufacturing experience in textile/garments.

We have focused on sewing sections of woven and light knit*. Why?

1. Simplest manufacturing process: the production line

1. Simplest manufacturing process: the production line

2. Studying numerous production units with 50-100 workers

3. Good ways of measuring and benchmarking productivity

So what do we do? And what do we want to learn?

What do we do?

Collect production data from several factories

Measuring productivity: Sample of raw data

One factory for one day… and other files on quality defects and absenteeism.

What do we do?

Measure Productivity

Measuring Productivity

Efficiency = Output minutes / input minutes

[# pieces * SMV] / [# operators * runtime in minutes]

Typically:

• 35- 40% in Bangladesh (best ~ 60 percent)

• 70 – 80% in China/Sri Lanka

Garments in Africa

What are the pre-requirements to develop a vibrant export oriented garment sector?

1. Favorable trade policy (AGOA, MFA*)

2. Access to inputs (cotton, fabric*)

3. Access to finance:

- Set up costs low in Cut Make Trim (CMT)

- Back to Back L/C

4. Infrastructure (Roads and Ports)

5. Electricity

6. Skilled labor force

- Operators (mostly women, learn fast)

- Line Supervisors/Line Chiefs: this is the challenge.

Good Management

Do Line Supervisors matter ?

Operators are moved with some frequency across lines, esp. when there are large numbers of absent workers or style changes

Supervisors are move much less frequently. (~7% moved over 4 months in sample from another project.)

But, Do supervisors matter? First, look at what workers say are the most important tasks of supervisors:

Characteristics were placed in overlapping groups of three, and respondents were asked to rank

them. Scored 3 if the characteristic was ranked first, 2 if second, 1 if third.

Common Understanding

1. Trust is key to well functioning relationships

2. A “common understanding” is key for trust (Gibbons and Henderson 2012)

3. Measurement (1-2 SVs + two randomly selected operators): • Now I am going tell you some things about the factory. Please tell me whether

you totally agree, somewhat agree, somewhat disagree or totally disagree.

It is OK if a worker doesn't come to work without giving any prior notice because his/her child is sick

It is OK if a worker doesn't come to work without giving any prior notice because of heavy rain

It is OK if a worker doesn't come to work without giving any prior notice because her sister is getting married.

Next Steps

1. Leverage connections with buyers (H&M, Tesco, Sainsbury), IGC and our team expertise in collecting and analyzing production data to benchmark African’s capabilities in the garment sector.

Ethiopia

2. Better understand the role of “trust” in shaping firms’ organizational choices and – ultimately – productivity in a variety of contexts in Africa

Where does trust come from? Which organizational practices promote it? Training? Information Systems?
