Preconceptions about ordinary people are not very useful for positive information. However, preconceptions about a developer's work pattern can be excellent underlying data for development team management. According to actual experience, schedule adjustments were of great help through preconceptions about developers' development habits/patterns.
Schedule adjustment through preconceptions examined with two cases
In the case of Developer A, this friend is always bound to take longer than expected
- A usually processes shared schedules tightly or tends to be a little late. If A presents a 5-day work schedule, the manager can use this as a reference and establish a plan with a buffer of about 6 days. By reflecting this preconception, A can do his best to complete the work within the schedule without any burden, and as a result, a relationship of trust is formed.
In the case of Developer B, always take the schedule with a buffer
- Conversely, B approaches the schedule with a relaxed style. The 5 days that B mentions are likely to be kept, and in case of an urgent schedule, it is possible to explain the situation and bring a buffer to reduce the schedule slightly.
Reasons for utilizing preconceptions
- Efficient schedule adjustment: By considering delays and matching the presented schedule stably, time delays are reduced in advance until development is completed.
- Building a relationship of trust: Conversations that can embarrass developers and managers are reduced, and through a high degree of understanding, they trust each other's words (correction through preconceptions) and development can proceed based on that trust.
Reasons why it is difficult to create preconceptions
- Attention: It requires a great deal of focus and attention on each developer, from their usual development habits to their lifestyle at times.
- Experience: Experience in development and development management is essential, and all experiences from the past history of developers to the present must be recorded and remembered.
- As the number of developers increases, the management of the above two items becomes exponentially difficult.
Utilization of professional tools
In order to understand preconceptions, that is, the habits and patterns of developers, it is necessary to use professional tools:
- Real-time work status monitoring
- Analysis of individual developers' work patterns
- It helps managers to lead the team more professionally by providing effects such as improved accuracy of schedule prediction and adjustment, and gives 'experience'.
