Why provide diverse services?

The Apple Event was held on September 7th.

Smartphones haven’t evolved much (although there are rumors that the addition of functions was intentionally suppressed to keep the price down), but I wanted an Apple Watch that fully supports underwater operation.

When I look around myself, I am completely covered with Apple products. Previously, l used both Windows and Mac as laptop, but only MacBook. There was a time when I used cheap Android smartphones, but now I’m an iPhone only user. Watch is Apple Watch after NIKE Fuel Band and Fitbit. Recently, I’ve been thinking about transferring Evernote to iCloud’s Note, which I feel has a lot of performance and functional deterioration. . .

Looking at such an environment, I remembered the churn rate of mobile.

As you know, over the years, telecom carriers have gone into banking business, electric power business, and other services that are completely unrelated to telecom services. What are your thoughts on that?

One of the main reasons for this is to prevent cancellations. There is actual data that the churn rate is lower for those who subscribe to multiple services.


Doing new business services has the aspect of diversification of management, but have you ever thought that there are services that are not so different from other companies? It’s the same service, but it’s the same company’s service, you can use a common ID, you’ll get more points, and you’ll have one bill. You often use services from the same company.

You used to see a lot of comparison sites for population coverage or communication speeds, but now we don’t see much of those comparison sites. I think it’s a matter of course and it’s no longer a point of differentiation (Although it is very difficult to build network). There is also the aspect that telecommunications carriers provide new services in order to protect their most important telecommunications business.

I once saw a famous person who was active in a certain telecommunications company make a comment that “Communication service companies should concentrate only on their original communication services” I think it is difficult to differentiate with a service that has become obsolete, and it is difficult to innovate. The iPhone has not seen any noticeable evolution these days.

when providing your own services, it may be important to think about Upsell businesses that are linked, not just a single service, but a linked.

The real goal of agile development

The real goal of agile development is “To achieve results on time as promised”

It sounds obvious, but it’s been a long time since agile development became popular, and I also participated as a product owner, looked sideways at the support activities of agile coaches, and had some experience, but I often see this goal is lost.

Specifically, we often see that agile development has an unclear output for the deadline. Therefore, some people recognize that agile development has the advantages of development flexibility, but it has the disadvantage of not achieving results on time, and we often receive such opinions. Isn’t that a mistake?

Originally, whether it is waterfall or agile, the development method is different. In the end both ways should commit output to the promised date and result to the members of the steering committee.

So why is “agile development = cannot promise a goal” ?

This is often due to the premise of a variety of limited resources in the field. For example, even if it’s clear that the number of development members is not enough or members skills in the middle of development, you can’t increase or change members due to cost and required skill. Even if tools are not sufficient, you can’t change the tools due to company security. With such a premise, even if you see behind in the process of agile development towards your goals, you can make improvements with limited resources, but you can’t do much more. Therefore, inevitably, it becomes impossible to commit to the final result.

Agile development is just one of the development methods, and it’s originally one of the elements in a big project. To complete the project, you must meet the deadline and produce output. To that end, not only you introduce agile development, but you need to prepare people, goods, and money to reach our goal. If you look at the burndown chart and the work is behind schedule, you can add human resources, introduce more effective tools, spend money on it, and so on. If nothing is done, it is naturally impossible to recover it with a delay from the plan. When introducing agile development, I feel that you don’t often talk about it from such a viewpoint.

A few years ago I had the opportunity to meet and talk to Jeff Sotherland. At that time, Jeff was also concerned about this point. When it comes to agile development, there are many people who feel the benefits of the development method, Scrum and Sprint, but they are misunderstood that they do not commit the results and may not introduce it. He is also had a clear opinion that whether it was waterfall or agile commit to output.

How is agile development around you incorporated into the project? If you are focusing only on development methods, you may be more aware of the essence of agile development if you review it from this perspective.
