"Oh, Lao Zhao, why are you here too?"

"Hey, Bai Quanyi, you are saying this, why can't I come?"

"Okay, I won't compete with you for this, I said, how much do you know about this project?"

"How much do I know? I know as much as you know!"

Two middle-aged men in naval officer uniforms stood at the entrance of Dagang Naval Ship Academy. They looked up at the August 1st military emblem hanging in front of the college gate, and couldn't help but push their big-brimmed hats, with their expressions even more solemn.

"The last time I came back was eight years ago. I didn't expect you to be the captain of the destroyer!"

"Haha, isn't it just two years later than you?"

"Zhao Yulu, Bai Quanyi, are still rubbing at the door!"

A gray-haired soldier in his fifties walked out of the ship academy. The two people who were still quarreling before quickly stood attentively and saluted with excitement.

"chief of staff!"

Zhu Hanting raised his hand and greeted the two of them, looked them up and down, and smiled and said, "I have a good mental state, don't stand at the door, come in with me."

"Yes!" Zhao Yulu and Bai Quanyi looked at each other, followed Zhu Hanting, and walked towards the Ship Academy in a row.

Bai Quanyi and Zhao Yulu exchanged their eyes, but in the end they were still a little uncontrollable and shouted: "Report!"

"speak."

Zhu Hanting didn't look back, and the voice came over.

"Chief of Staff, this time I notified us to return to the Ship Academy, what is the mission?"

"Why, what task do you want to pick and choose?"

"Chief of Staff, I don't mean that!" Bai Quanyi was startled and quickly explained: "Isn't this how to prepare more targetedly after knowing the content of the mission?"

"Don't worry, you don't need to prepare anything." Zhu Hanting said as he walked: "Comrades from the Naval Equipment Argumentation Center, please come and provide some advice on the research and development of new equipment."

“Let’s give us advice?”

Bai Quanyi and Zhao Yulu couldn't help but look at each other, a little surprised. China's technology research and development is in the Soviet style, and it always emphasizes that people adapt to equipment rather than equipment adapt to people. As for the navy, it is even more useful. What ergonomic engineering, ease of use, etc. are never in the consciousness of technical developers. As for the front-line officers and soldiers, it is often found in the developers' own imagination.

It’s not that there is no time for users to provide advice, but it is mostly a follow-up survey that takes a while after the equipment is developed and applied. But at that time, many problems were not changed, and even if there is any opinion, they could only continue to use them. People were called over to give suggestions during the development of new equipment, which was really rare.

"Well, this task is very important." Chief of Staff Zhu Hanting nodded and said with a cautious expression: "You must be careful in cooperating with the work of scientific researchers. This project may be a leapfrog development for our Navy. If you can perform well in your work, you may have a chance in the future... It's still too far, but it's always right to do it well."

Zhu Hanting said half of the hidden sentence, and the seduced two people felt itchy. They glared at each other like a sign of separation, and nodded vigorously.

When Bai Quanyi and Zhao Yulu walked to the playground in front of the teaching building by the sea, they found that the navy had really invested a lot of money this time. In order to cooperate with the work of the R&D personnel, the crowd waiting in the playground alone was visually more than 200 people. Not only were there destroyer captains like Bai Quanyi and Zhao Yulu, but there were also visually confirmed that there were also frigates, supply ship captains and deputy captains. In addition to the captains, there were also many commanders, navigators, guns, sailors, radar, electromechanical, watches, and sonar departments. Even the military logistics and kitchen squads saw similar figures.

With the current lineup alone, you can drive the Zheng He training ship parked in the Dagang Ship Academy out.

"Okay, you guys will join the list."

"yes!"

Bai Quanyi and Zhao Yulu quickly trotted and stood in the queue, and then were surprised to see that Zhu Hanting, the chief of staff of the fleet, was standing straight at the front of the queue.

After a while, two men and women ran out of the teaching building. The man was so young that he looked in his early twenties. The woman looked quite mature, but still looked too young.

"Where are their leaders?" Bai Quanyi said with a crooked mouth and frowned in a low voice and complained to Zhao Yulu: "Our 200 people are standing under the sun, what does it mean to be like these two young people?"

"Who knows, the leader is behind? These researchers don't always have eyes on the top of their heads." Zhao Yulu curled his lips and shook his head slightly.

However, just as Bai Quanyi and Zhao Yulu looked at each other, the man and woman ran straight to Zhu Hanting and kept saying something. But no matter what they said, Zhu Hanting was always shaking his head.

"Mr. Hu, Dr. Fan, please arrange the task." Zhu Hanting stood like Song, looking ahead, and letting Hu Wenhai and Fan Xiaohong persuade him, he remained motionless.

"Chief Staff Zhu, how can we talk when you stand here-" Hu Wenhai couldn't laugh and cry: "You can't treat you as an experimental staff who cooperates with our work, right? You just stand in front and help us organize our work, isn't it good to stand in front?"

Zhu Hanting shook his head stubbornly and said with a squint: "Mr. Hu, just treat me as an ordinary soldier, and arrange the tasks as you should. Since I have inspected the foreign combat system, I dreamed that one day our country's warships will be as advanced as the United States and Britain. The future war will no longer be like ours, just knowing to aim at the target and pull the trigger. If you have strong strength and courage, you can win the battle. If you can't keep up with the development of the times, you won't even know which button to press. As the chief of staff, can I not set this example?"

Hu Wenhai and Fan Xiaohong looked at each other and smiled helplessly. What the chief of staff of the North Sea Fleet was really not something they could persuade.

Seeing that Zhu Hanting really made up his mind to participate in the development task himself, the two persuaded him for a long time, but finally had to agree.

"Let me introduce you to you. I am Hu Wenhai, this is Dr. Fan Xiaohong. From today on, we will be responsible for everyone's training and work management." Hu Wenhai stood in front of these naval officers and soldiers, and was sweating profusely in front of the scorching sun by the sea: "The task we want to perform can be said to be simple and very difficult. You don't need to go up the mountains and down the sea, nor do you need to charge in the fire of artillery fire. But it is also very difficult, because what we have to do is to completely change the previous operation mode of warships. It can even be said that we need to reconstruct the combat mode of the entire naval battle. This is the technology and combat intelligence system we want to develop."

Hu Wenhai's words made a low voice sound in the disciplined queue.

Bai Quanyi widened her eyes and glanced at Zhao Yulu in disbelief. Sure enough, she was so surprised that she couldn't stop talking about her.

"I said what happened? I asked a little kid to be our leader? What are the above thinking? Such a big kid, even the soldiers under my command think he is too young."

"I don't know, just like you, I came over after getting the order." Zhao Yulu rolled her eyes, and the two of them looked at each other speechlessly.

"stand at attention!"

Zhu Hanting shouted, and a sound of his straddle sounded, and the queue suddenly became silent.

"I'm sorry, Comrade Hu." Zhu Hanting personally saluted Hu Wenhai and said apologetically: "My naval officers and soldiers are not disciplined, so you have to worry!"

Hu Wenhai waved his hand quickly and said laughing and crying: "What did Chief of Staff Zhu say? I am a little younger. Okay, then I will continue to assign tasks next."

"This mission does not require everyone to sacrifice their lives, but we are required to start our brain cells to provide advice on the combat mode of our army's future naval battle. Under this demand, we need to learn a lot of professional knowledge from the beginning. Courses such as automation control, computer principles and software engineering will be the main learning content for everyone in the next period of time..."

Hu Wenhai's words made the naval officers and soldiers present look at each other. They were not afraid of sweating and bleeding, even if they really went to the battlefield to charge, many people would not blink.

But I have to talk about learning automation control and computer principles, as well as software engineering that I have never heard of before.

This is really a death-taking.

The academic level of the front-line officers and soldiers of the People's Liberation Army has to wait until at least the late 1990s. Before that, if you want to talk about the professional level of the ship, I believe that many naval officers and soldiers will not make any mistakes. The basic math level, the Navy will definitely look at the big brother of the Army. However, computers not only need to learn mathematics and headache-inducing electronic circuits, but also inseparable from English proficiency.

Thirty years later, college students who take the CET-4 and CET-6 are like Dui, not to mention that these naval officers and soldiers are generally in their thirties or forties, and the golden age for learning has long passed.

However, this is helpless, and the development of combat systems is not that difficult in terms of hardware. In fact, by the advanced warships developed by countries in the 1990s, especially the combat systems developed by Britain and France in the 1990s, the hardware processors used by Motorola 68000 series CPUs. Various sensors and controllers were not insurmountable for China in the 1980s.

The true essence of the combat system lies mainly in its software system. First, it is the transformation of naval military thinking, from pursuing the power of weapons to pursuing the accuracy of information. The common thin skins and large fillings of modern naval warships can put missiles that can hit the soul into World War II, and I am afraid that even the skins of the battleships will not be able to chew the skins of the battleships. This change is the change brought about by combat ideas.

In war beyond the visual range, obtaining information is better than the power of weapons. This information is not just information such as the location of local warships, but also the mastery of the status information of the entire warship.

How to organize the acquisition and analysis of battlefield information is the function of combat system software. Just like any software development process, if you want to build a modern combat system software, the first thing you need to do is to analyze the software requirements.

Normally, there are many ways to analyze software requirements. Such as interviews, questionnaires, group discussions, business processes and scenario connections, are common requirements analysis methods.

However, in the process of software development, the nightmare that programmers hate the most but cannot get rid of is the change of demand. Programmers and demand analysts are always unable to fully meet the needs of users. There are both technical reasons and demand analysis problems. Some users are clear about their needs but cannot describe them clearly, some can clearly describe them but have no idea about what specific needs, and some users' needs change three times a day. More users are not clear about what functions they have in mind. After the software is developed, they are not happy with them. There are only a very small number of considerate users who are clear about their needs and have basic software engineering knowledge, which is simply a blessing for programmers.

Unfortunately, the users of combat system software requirements are a group of naval officers and soldiers who cannot explain their needs and have no idea about how to realize information-based combat operations and have extremely strict requirements on software applications.

Hu Wenhaisi thought about it and had to use a stupid method in the face of this situation. Since the user population is so bad, we should cultivate the user quality first.

It doesn’t matter if we don’t understand the concept of information-based combat. Let’s first make up for what informatization is. Knowing what informatization can do, these naval officers and soldiers can naturally combine their own work to clearly express the functions that they hope the combat system can achieve.

It doesn't matter if we don't know how to describe the specific needs of the software. We start learning from software engineering and we will naturally know how the software implements these functions.

In the end, these naval officers and soldiers were the group of programmers’ favorite users. They not only knew their needs, but also clearly expressed the way of implementing the needs.

But the hardest thing is that these naval officers and soldiers from all over the world have learned three courses: automatic control theory, computer principles and software engineering. It is not a big problem to be a coder who has been a half-dog month after thirty years.

For these thirty or forty-year-old naval officers and soldiers whose knowledge system has been established, it is really more painful than going to the battlefield.

This is not. When the mission was issued, all of these naval officers and soldiers had a bitter face. But seeing that Chief Zhu, who was in his fifties and had commanded a torpedo boat to sink the Kuomintang Taiping frigate, did not object at all, and the others had to bite the bullet.

The English reading sounds floating out of Dagang Ship Academy every morning are a common sight, but if someone can walk into this teaching building near the sea, you will find that the people gathered on the beach in the morning were all senior naval cadres with flowers on their shoulders.

Among them, the earliest ones, the loudest reading and the most serious study, was an old man in his fifties.

"Teacher Xiao Hu, what does this mean by top-down? Is this different from the previous segments and the previous ones?"

The first training course after breakfast was software engineering taught by Hu Wenhai himself. It was said to be software engineering, but this course does not mean to train coders, nor to train how to code. Instead, it is the management course for project managers of management coders, which has little to do with program development itself. Before the "software crisis" that year, few people paid attention to this management science, and naval officers and soldiers did not need to be coders themselves. However, for naval officers and soldiers, understanding modern management science in this way can be considered a leading curve solution of Mr. Hu.

As soon as Hu Wenhai entered the door, he was stopped by Zhu Hanting. The old man in his fifties still held his notebook with respect like a student and humbly asked his own questions.

"In fact, this is not a variant of the shard-free model. This is actually two different ways of solving problems, but the execution methods are somewhat similar. When our Xinke company was managing the factory, it implemented a system called cost reversal. The method is like this. We first determine a competitive price, and then calculate the cost of the product required by this price. Based on this cost, we decide how to invest capital for production. All our measures and methods are to achieve such a clear purpose. Simply put, we set a top-level goal and then refine it layer by layer. In this process, the tasks and implementation methods at each level are clear. In fact, there is no clear overall goal and a clear way to achieve it, so we have to delegate autonomy, let the lower one set the goal and then choose the route of implementation on their own, which will bring risks and uncertainty."

"Top-down management is based on a full understanding of the entire lower-level information, analysis and prediction of the execution process, and even modeling and simulation. This is like the Liberation War that year. Why our army was able to organize battles well is based on a reliable command system and an effective mastery of grassroots information. This itself is also a sample of design and execution from top to bottom. As for the reactionaries of the Kuomintang, of course, it is impossible to achieve this point, and we can only count wherever we go."

"In fact, our new science is also learning from the old traditions."

Hu Wenhai's speech speed was as slow as possible, because Zhu Hanting would meticulously record every word he said in his notebook.

After stopping his explanation, Zhu Hanting even thoughtfully and said, "I didn't expect that there were so many statements in the revolution back then. So, it has such a great effect on helping enterprises produce?"

Hu Wenhai nodded: "It is indeed possible, but the management method has requirements for employee quality and material foundation. Process-based management does not require high management level. But to reverse the cost, an enterprise must at least be able to fully grasp all production processes. For example, the 7 billion project in Iraq. First, there are specific and clear requirements for this project, and then solve the problems involved in this project. In addition, Xinke Company is now carrying out management system reform, and the group's subordinates will add various business units. These business units are for the promotion and establishment of certain large-scale projects, and its guiding ideology can also be understood as a method of face-to-face. But the problem is that such business units need to be able to coordinate the strength of several branches and subsidiaries, which is for current state-owned enterprises..."

Hu Wenhai didn't finish his speech, but Zhu Hanting couldn't help but nodded. The barriers between domestic state-owned enterprise systems are so strict that it is very difficult to break. Just talk about the Pusan ​​localization project, what about the vice-state-level project? The agricultural machinery system has useful technologies, but because of the different systems, it can only be introduced from abroad again. The relationship between the State-owned Enterprise Corporation and the branch is even more complicated. China Shipbuilding Corporation can nominally manage all shipyards, but can it mobilize the resources of its subordinate enterprises without limit like Xinke Company?

But even so, Zhu Hanting still felt that a new world was opened in front of him.

Seeing that the chief of staff of the North Sea Fleet were so active in learning, the other naval officers and soldiers had to bite the bullet and try to digest the knowledge that was like a heavenly book.

In the morning, these naval officers and soldiers were studying, and in the afternoon, they were going to help researchers develop software.

The work on combat system software has just begun, and their afternoon job is to help researchers determine the software needs.

This process mainly uses interview and prototype methods.

There is no need to say much about the interview. We will talk face to face with users to collect demand information. The advantage of this method is that it is intuitive and convenient, but the disadvantage is that it is more emotional and not easy to quantify.

Therefore, in the development of subsystems, it is necessary to adopt a method that is easier to explore the deep needs of users.

This method is the prototype method.

Simply put, the prototype method is to quickly develop a basic version of a system using advanced software. Then, let users constantly feedback, supplement and modify during use. This method is most suitable for users with unclear needs.
To be continued...
