Something about Kaizen

Tư tưởng Kaizen là:
- Liên tục
- Từng tí một

Việc Kaizen nói chung:
- Gì cũng được, không hạn chế chủ đề, nội dung

Mình hơi dốt toán nên hỏi một câu:
Nếu cứ mỗi 2 tuần ta cải tiến năng suất lao động được N = 1% thì sau 1 năm năng suất lao động của ta tăng mấy lần?

1% là ít, nhưng sau 1 năm thì nó là con số khác.

Nếu

Kiro-san còn phát xít hơn:
- Đã là Kaizen thì cấm cải tiến quá nhiều ;)

Being too smart is *your* problem.

Thông minh quá cũng là vấn đề. Đây là một số biểu hiện:

1. Chán dự án
2. Không nhìn thấy tương lai
3. Anh em xung quanh thấy "ổn", trong khi mình thấy nhiều issue, rooms for improvement
4. Sếp không có tầm hình cho chính hắn, cho bạn, cho phòng/công ty
5. Công ty không thấy được giá trị của bạn
7. Không ai chỉ lối/hướng dẫn được cho mình

Vậy phải làm gì khi đó?
1. Tìm việc mới
2. Trở thành lãnh đạo
3. Làm việc 1 mình

Scrumbut: Is that good or bad

​​
Simply but, "Scrum but" means "We are using Scrum, but <however|some reasons>...".

That means, it is meant to not to be truly Scrum.

I am sorry for using the word "Scrumbut" but I don't mean to blame or insult anyone ;)

Ken Schawaber recommend​s​ replacing the word "Scrumbut" with "Scrum And.

"Scrum And" is a path to continuous improvement.
Let's say we are at Scrum+0. Let's cirle to loop PDCA and move to Scrum+1, Scrum+2 and so on.

Examples of "Scrumbut":

  1. "We use Scrum, but we don't do Retrospectives (for some projects) for every sprints"
  2. "We use Scrum, but we don't have a working software after 4 sprints"
  3. "We use Scrum, but sometimes our managers give us special tasks"

Is Scrumbut bad?
No and Yes. Scrum is an Agile toolkit and it is used as a management method. To meet our goals, adopting or transforming Agile or do what we think is needed.

"Refactoring Doesn't Improve Code Quality"

Hoang mang quá :)

(Study finds that)

"Refactoring Doesn't Improve Code Quality":
- "here is no quality improvement after refactoring treatment to the source code"
- So, what are the impacts of source code refactoring?
- It is said the source code refactoring improves maintainability and extensibility - two aspects of quality but how about the general quality?
- Do the authors of this paper understand what is source code refactoring???

What's the difference between CIO and CTO?

Câu hỏi:
- What's the difference between CIO and CTO?
-

​What they have in common:
  1. ​In both jobs, a key role is helping technologists understand what the business needs and helping the business understand what the technology can do for them.
  2. Both roles require a strong technologist with a strong grasp of business (kind of a corollary to the last point, but slightly different).
  3. Both should be strategic thinkers.
  4. Both should be excellent leaders.

How they are different:
  1. I see a CTO as primarily focused on the top line while the CIO is primarily focused on the bottom line.  There's some cross over, but I think this is a valid distinction.
  2. A CTO is primarily concerned with external products and customers while a CIO is primarily concerned with running the business (internal products and customers).
  3. In an ideal world, the CTO runs the product development organization while the CIO runs the IT organization.
  4. If you have to choose, being a strong technologist is more important for the CTO, while being a good manager is more important for the CIO.
  5. A CIO has to be operational and understand how to build repeatable processes, reliable systems, and the organization to run them.  A CTO doesn't necessarily have to have these skill if backed up by a strong operational person in the role of CIO. 

RACI and characteristics the the two roles:

Chief Information Officer

  1. Serves as the company's top technology infrastructure manager
  2. Runs the organization's internal IT operations
  3. Works to streamline business processes with technology
  4. Focuses on internal customers (users and business units)
  5. Collaborates and manages vendors that supply infrastructure solutions
  6. Aligns the company's IT infrastructure with business priorities
  7. Developers strategies to increase the company's bottom line (profitability)
  8. Has to be a skilled and organized manager to be successful


Chief Technology Officer

  1. Serves as the company's top technology architect
  2. Runs the organization's engineering group
  3. Uses technology to enhance the company's product offerings
  4. Focuses on external customers (buyers)
  5. Collaborates and manages vendors that supply solutions to enhance the company's product(s)
  6. Aligns the company's product architecture with business priorities
  7. Develops strategies to increase the company's top line (revenue)
  8. Has to be a creative and innovative technologist to be successful

What Makes a Great CTO?

Câu hỏi: What Makes a Great CTO?
Chủ đề: RACI của CTO và CIO khác nhau thế nào?

Evangelism

The CTO will serve as the company spokesperson for the product development/technology organization, demonstrating leadership in the community, with developers, partners and customers. This is often measured by establishing a university relations/recruitment program, and sponsoring or participating in at least two events per year in the developer community.​

Organization

Build an excellent organization, with a strong management team committed to developing the skills of your employees. We typically measure effectiveness here by looking at development plans for all of the employees, the retention rate, and the evaluation of the managers and the overall product organization by the rest of the company.

Delivery

Make sure this organization can rapidly, reliably and repeatedly deliver quality product to market. There are several measures of delivery, including some measure of the quantity of work delivered, the consistency and frequency of release vehicles, and the quality/reliability of the delivered/launched software. Some organizations just look at reliability here, but productivity in the sense of quantity and quality is the real key.

Architecture

Make sure the company has an architecture necessary to deliver the functionality, scalability and performance it needs to in order to compete and thrive. The measures for architecture will vary based on your business, but in general we look to track and measure headroom/infrastructure work, and measure site outages due to architectural issues.

Discovery

Make sure that the architecture and senior engineering staff are participating actively, and contributing significantly, throughout product discovery. If your engineers and architects are only being used to write software then you are only getting a fraction of the value from them you should be. We suggest you track the participation of the product development/technology organization in product discovery (both duration and coverage), and the number of innovations that are credited to the engineering/architecture participant. It is also useful, although a little sensitive, to track changes to schedule post-discovery (churn), as you are always trying to reduce churn.

"bạn không đau đầu về những người ra đi, bạn đau đầu về những người ở lại"

Giữ được nhân viên hay không, phần lớn do sếp (trực tiếp). Anh có đủ lý thuyết và kinh nghiệm về chuyện đó.


Hơn nữa, người ta nói: "bạn không đau đầu về những người ra đi, bạn đau đầu về những người ở lại". Nghĩa là, đi nhiều không phải là vấn đề, vấn đề là người ở lại có làm được việc không.


"Most people don't quit their jobs, they quit their managers"

Compare DeployGate and TestFlightApp

DeployGate:

- Japan's mixi đang dùng
- Crowd based testing
- free to try: 4 apps, 20 devices, +2 pax
- real-time testing
- Không cần SDK, device ID để test

Dùng thế nào?
- Test thử app của mình trên nhiều, nhiều thiết bị (mà bên phát triển không có)

Ghi chú thêm:
- Với apps, đặc biệt là Android based, bên phát triển không thể có đủ thời gian, công sức, tiền bạc để test trên tất cả, hoặc chí ít là nhiều thiết bị khác nhau
- Số lượng devices rất nhiều: Android 2.x, 3.x, 4.x, 5.x, iOS cũ/mới, của rất nhiều hãng khác nhau
- Người dùng thật trải nghiệm rất khác nhau
- Với dự án không có QA chuyên dụng thì nên dùng những dịch vụ test on-the-fly, crowd based

DeployGate vs. http://testflightapp.com:
- Đều dùng để test
- Nhưng mỗi dịch vụ có cách test khác nhau
- Nên phối hợp cả hai (nếu đủ kinh phí)

Giá:
https://deploygate.com/pricing
Biz plan: $120/month, 100 apps, 30000 devices, +100 pax.

Migrating from chatwork to slack (?)

Bên mình (phát triển phần mềm, hệ thống) đang xem xét chuyển công cụ chat từ Chatwork.com sang slack.com

Xin chia sẻ một số thông tin đã tìm hiểu được.

Câu hỏi và yêu cầu đặt ra là:
- Dùng công cụ nào để giúp team members (ở nhiều nơi), giao tiếp hiệu quả?
- Công cụ giao tiếp này tích hợp với các công cụ phát triển (phần mềm) khác như task management systems, content management, source code management systems
- Giao diện đơn giản, thân thiện
- Thỏa mãn nhiều đối tượng: testers, developers, product owners (non-tech đi)

Các công cụ này phải hỗ trợ cả text messaging, voice chat và screen sharing

So sánh Chatwork và Slack:

Something about Slack (versus Chatwork)

Something about Slack (versus Chatwork):

- Easy to mention people, group with @, just like FB, twitter: @peopleName, @groupName, or @all.

- (Paid) Connect customers/external partner: Get outsiders to the channels.

- Really well integration: 
   + Integrate with Jira, Trello. Change assignee on Slack.
   + Paste files on Google Drive (and dropbox). Preview/view like (like FB's file), not only showing just the links
  
- Great search engine: Better than chatwork.

- Better UI/UX than Chatwork. More Ajax.

- Great API, much better than Chatwork.

- English is more friendly with international users.

- 1B$ invested. Great potential, great investment: http://techcrunch.com/2014/10/23/slack-is-raising-another-round-at-up-to-a-1b-valuation/

- Many SepTech's members have been using Slack and they are giving very postivie feedbacks about Slack.

Google Apps Script (+Slack) versus Chatwork + Chatwork API.

Google Apps Script (+Slack) có lẽ mạnh và uyển chuyển hơn Chatwork + Chatwork API.

Ví dụ về phần mềm quản lý thời gian (giờ về, giờ đến, xin nghỉ...) bằng Google Apps Script +Slack
https://github.com/masuidrive/miyamoto

Điểm nhấn:
App này scan text có dạng:
- Ohayo
- Otsukare
- ...
và tự phân tích, sau đó đưa vào Google Drive

It is almost true that there is no dedicated QA in Facebook

A Facebook engineer confirms "It is almost true that there is no dedicated QA in FB".

QA ở FB thực hiện thế nào?
- Automated testing
- Dùng chính các công ty kết nối tới hệ thống/dịch vụ của FB để test (tích hợp)
- Nhân viên FB dùng và test luôn FB
- Test các bản pre-release chặt
- Hiện error log và xem nó, luôn và ngay, ai cũng xem

Metrics cho QA là gì
- KLOC
- Thời gian để chạy (automation test)
- Tỉ lệ thành công của users report, graphs of workflows
