\n\t\t\t\t\t\t\t\t\t\nWe wanted to follow up our previous piece about how to grow as a data scientist <\/a>with some other skills senior data scientists should have. Our hope is to bridge the gap between business managers and technical data scientists by creating clear goals senior data scientists<\/a> can aim for. Both entities have to take on very different problems. Both benefit when they are on the same page. This is why the previous post focused so highly on communication. It seems simple, but the gap between technical and business continues to grow as new technologies keep getting piled on every year. Thus, we find it important that managers and data scientists have a clear path of expectations.\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t

\n\t\t\t\t\t\t\t\t\tWe find that is beneficial when data scientists are starting their journey that they focus heavily on the technical aspects. This means programming, queries, data cleansing, etc. However, as data scientists grow. They need to focus more on design decisions and communication with management. This will multiply the impact of the more experienced data scientists knowledge. Instead of being stuck in the day to day of coding. They can make higher level decisions and help the younger data scientists if they get stuck. More experienced data scientists benefit both themselves and their companies more when they are utilizing their experience to help make design decisions that simplify complex systems, optimize data flows, and help make decisions on what projects are most pertinent.\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t

\n\t\t\t\t\t\t\t\t\tThe role of an engineer is to simplify a task. If you have ever built or seen a Rube Goldberg<\/a> machine you will understand the idea of over engineering a simple task. Some data scientists algorithms and data systems would look more like some crazy mouse trap held together by duct tape and gum instead of an elegant but effective solution. Making simpler systems means the systems will be easier to maintain over time as well as provide future data scientists the ability to add and take away modules as needed. The next data scientist taking your position will thank you if you create a simple framework. On the other hand, if you use 3 different languages, 2 data sources, 10 algorithms and leave no documentation, then just know the future engineer is cursing your name under his breath.\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t

\n\t\t\t\t\t\t\t\t\tOne of the big values strong data experts should provide is tying together data sets that might not inherently have a primary or obvious connection. Data can represent a person or business\u2019s day to day interactions. Having the ability to find statistical patterns in this data is what allows data scientists the ability to help decision makers make wise choices. However, the data you would like to mesh together is not always on the same system or the same granularity.\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t

\n\t\t\t\t\t\t\t\t\tThose who have worked with data will know it is not always integrated together nicely in one database. Finance data is often kept separate from IT Service Management data, and outside data sources might not have the same level of aggregation. This is a problem because to find value in data sometimes requires data from other departments and systems.\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t

\n\t\t\t\t\t\t\t\t\tFor example, what if you are provided medical claims, credit card and criminal rates of neighborhoods and want to figure out how these socio-economic factors affect the patient?. Some sets of data might be on a person by person level while the others might be on a street or city level with no clear method to connect the the data sets. What is the best way to proceed? This becomes a design issue that one, must be recorded and two must be thought out.\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t

An experienced data scientist will have the intuition on how the data can be joined. Mostly because they have already tried hundreds of methods that don\u2019t work. Often times, the closer you can combine both data sets to person by person the better. So if region or city happens to be the lowest level (Lowest level refers to granularity of the data, like person level, household level, street level, city level, state level, or many other groupings ) of connection, then that would be a great place to start.\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t

\n\t\t\t\t\t\t\t\t\tData science is complex field that requires an understanding of data, statistics, programming, and subject matters. In order to grow, data scientists need to be able to simplify and distill these complexities into algorithms. They need to be able to focus more on making design decisions. This helps maximize their knowledge and experience that they have.\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t

\n\t\t\t\t\t\t\t\t\tSenior data experts provide the largest impact for both themselves and their companies when they go beyond their technical abilities. The value they bring to the table is their experience, it can help guide younger developers to make better design decisions, and help managers make better decisions on which projects will have the best ROI. In turn, this magnifies the impact of their involvement on the team.\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t
