Should a Scrum Master be Technical ?

Scrum master and technical skills - an analyses 

We are aware that we need to have some skills to work in IT projects. But are we aware of what are the skills required? Who needs to acquire which skill and how to achieve the same? Software development has an origin of 1950. Yes, we have progressed from structured programming to waterfall, incremental, iterative, prototyping, spiral, v-model, rapid appln dev, agile method, XP, SAFe, LeSS, etc. 

In the above-mentioned methods, there has been a need for different skills like designing, coding, testing, etc to work on each method. We also have people who specialize in different skills and call them developers, tester, architect, and much more. 

Scrum Master with technical background

When we talk about agile methodology and scrum framework we will first talk about three roles namely the scrum master (SM), product owner (PO) and the development team (testing and developers). There is clarity in what a PO does and also we know the role of a tester and the developer. But, there is always confusion about the SM. 

Since an SM work with the technical team, should a Scrum master have technical knowledge? To what extent this person should know about coding and engineering practices? Do they just need to be facilitator? Will the technical team respect them if they do not talk about technical terms in the meetings? 

The answers to these questions can be provided if we know the pros and cons of an SM with and without technical background.

3. SM will force the team to implement things on his way and this will create issues with the team.
4. Team collaboration will reduce and few will support the SM which will lead to biased decision making.  
5. They may time box correctly but many times fail to stick on to it as they may continue expressing their ideas not allowing the team to talk. This will lead to long discussions and even daily stand up meeting exceeds 15 mins.

Scrum Master without technical background 

“No technical background” does not mean this person lacks understanding of technical skills. They may not master the engineering practices and might not have worked on coding in the past. But, they will know the knowhow of how to handle technical team, projects and facilitate the entire process.

Benefits 

1. The SM without technical awareness will ask the team many questions and that will allow the team to think. This will improve their questioning ability leading to finding the right solution. Team performance will improve. The entire team will feel motivated. They will not hesitate to share their views. Empowered team will not just work towards achieving their goal but will own the entire process and work to complete the business goal joint handily. 
2. Sticking on to time is the key to success of agile projects. SM lacking technical skill will not get involved in the technical talk and thus will remind about the timelines. The team will get back to focus. 
3. The PO will get attached to the team and SM will act as a mediator.

Disadvantages 

1. Non technical SM will accept the acceptance criteria provided by the PO which might backfire at certain instances. 
2. They may overlook the work and not give importance to detailing which leads to gap in the process and product delivery.
3. Might become YES MAN which means the SM will accept everything the team tells feeling inferior about their lack of skills. This may mislead the team or make them overconfident. 

Final decision – technical SM or Non technical SM 

Now that we have seen both sides of the coin, we have given you a picture about being a technical SM and not. Let me now explain you whether you need to be a technical person or not to grow in your career and work on agile projects. 

One need not be a hardcore technical person as the role of an SM is to guide the team, organize meetings, support PO and facilitate the entire product development process. However, a basic understanding of the technicalities will help.
