The stand varies upon the distance between the circular rings. Even the circular rings are replaced by the bamboo straps.

The above patterns are used by the master craftsman to make different types of baskets. In our study we have considered one of the simplest patterns for making the basket. There were novice users and the master craftsman involved in the making of the bamboo basket. The process map of making the bamboo basket is illustrated in the Fig. 3.42.

The process of bamboo basket making starts with the collection of good quality of bamboo for the baskets. The collected bamboo is then stripped into required thickness which can be used in the bamboo basket making process. The strips are then colored and dried for making the baskets. Then after they are dried they are used in the making of the basket. The basket making begins with the simple patter, in this study we have taken few simple patterns like netting pattern, continuous pattern, start pattern. Once the pattern making begins the basket takes the shape as desired by the craftsman.
The final touch up is given at the top portion of the basket carefully by the craftsman After the observation of the bamboo basket process, some of the tacit knowledge involved in its making was extracted. This is shown in the Table-3.6 below.
Table.3.6: Extraction of tacit knowledge from bamboo basket making process Steps Processes Photos/videos Task/protocols
carried by the craftsman
Knowledge type Explicit
knowledge
Implicit knowledge 1 Collection
of bamboo stems
‘We collect bamboo stems which can be easily cut and made into fibres’
The moisture content in the bamboo stems helps them to turns into fibres
The craftsman knows exactly which
bamboo stem to select 2 Stripping
of the bamboo stems
‘We are able to work on the bamboo to strip them into fibres’
The selection of bamboo stems helps them to easily work on the bamboo
The
experience of working on the bamboo stem helps in the stripping it
3 Stripping of large pieces into smaller suitable thickness
‘The large strips of bamboo are cut into medium ones’
The
requirement leads to uniform length of smaller strips
The craftsman knows what is the required size of strip which can be made to a basket without wasting the bamboo 4 Colouring
of the strips
‘Sometimes natural colours are used in the colouring’
The colours give an aesthetic look to the final design of basket
Choosing colour
5 Drying of the coloured strips
‘After colouring we dry them’
~ The required
amount of time and temperature for drying 6 Using the
dry strips to make netting pattern
‘We sometimes use water during the pattern making of the basket’
The water gives required flexibility to the bamboo strip
The craftsman knows how much is the flexibility required during working on the pattern of the bamboo basket 7 Completing
the pattern to get a shape of the basket
‘we repeat the pattern to get the final shape of the basket’
The craftsman knows the exact radius to get the pattern
Radius of turning the strips to get the required basket shape
8 Finishing the upper portion and thus the basket.
‘final basket is made by closing the opening of the basket’
The final design is prepared
Final design contains certain craftsman errors which gives an unique look to the basket After the tacit and the implicit components of the bamboo basket making process was developed the next step was to generate the tacit markers from the protocol analysis. This was used for the
digitization of the whole basket making process. Fig.3.42 shows the generation of the tacit markers.
These markers are the indicators of the patterns which are followed by the craftsman in their process in different domain. In case of the bamboo basket making process some of the tacit markers are illustrated in the Fig.3.43.
Fig.3.43: Generation of the tacit makers in the Idol making process (Source: Author generated) The features like color, shape of the basket was considered for the classification of the basket from two different regions. Shown below in the Fig. 3.44 is a geometrical representation of the basket based upon the shape of the basket.

The next Chapter deals with the analysis of the data collected from the various case studies mentioned in this chapter. For each of the case studies the different tacit as well as the explicit component of the knowledge was analyzed.
